<p class="has-black-color has-text-color has-link-color wp-elements-29 wp-block-paragraph"><em>This story is the second in a series about Lake Helena and getting to know a place in nature over time. If you haven’t heard <a href="https://wildwithnature.com/2024/07/01/lake-helena-shorebirds/">last month’s installment, you can start there</a>… or just jump in here!</em></p>



<p class="has-black-color has-text-color has-link-color wp-elements-30 wp-block-paragraph">It’s a night in late June at a cattail marsh along Montana’s Rocky Mountain Front. The sun set more than an hour ago, and the pale, peachy afterglow has faded to blue over the backbone of the mountains. The marsh and the dark sky above it are filled with the calls and strange winnowing sounds of a dozen Wilson’s snipes (<em>Gallinago delicata</em>). And then, from somewhere deep in the marsh, we hear it again, that strange, deep gulping sound, <em>wump–CATchum! wump–CATchum!</em>: the distinctive call of an American bittern (<em>Botaurus lentiginosus</em>).&nbsp;</p>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/07/WillowCrRes_sunrise-1024x768.jpg" alt="Pre-dawn along the Rocky Mountain Front." class="wp-image-4367" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/WillowCrRes_sunrise-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/WillowCrRes_sunrise-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/WillowCrRes_sunrise-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/WillowCrRes_sunrise.jpg 1200w" sizes="(max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Pre-dawn along the Rocky Mountain Front.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-31 wp-block-paragraph">The American bittern is a secretive heron of dense marshes, uncommonly observed in Montana, and this is the first time that anyone has reported one in this marsh. We hear the bittern calling for roughly half an hour as the sun’s last glow fades away. The next morning we hear it once again in the pre-dawn hours, starting up around 4:20 am and continuing for roughly 40 minutes. Before sunrise arrives, though, it’s become silent, a ghost of a bird hiding in the wetland.</p>



<h3 class="wp-block-heading">Bitterns at Lake Helena?</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1-1024x768.jpg" alt="Listening for bitterns before dawn at Lake Helena." class="wp-image-4368" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1-1536x1152.jpg 1536w, https://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1.jpg 2000w" sizes="(max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Listening for bitterns before dawn at Lake Helena.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-32 wp-block-paragraph"><em>If a bittern is living here among these cattails, </em>I ask myself, <em>why not at Lake Helena, 64 miles away? </em>The cattail marshes are even more extensive there. And so, four days later, I arrive at Lake Helena at 4:00 am to listen for bitterns.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-33 wp-block-paragraph">It’s a chilly, still morning with skeins of mist rising from the lake. I’m standing in waders at the edge of the cattail marsh, cupping my hands over my ears and listening intently. I can hear the clear <em>wichety wichety wichety </em>of the common yellowthroats (<em>Geothlypis trichas</em>) and the chatter of the marsh wrens (<em>Cistothorus palustris</em>). A Wilson’s snipe winnows in the distance. From time to time, I hear splashes and sounds I don’t recognize from the marsh—but no bittern.&nbsp;</p>



<p class="has-black-color has-text-color has-link-color wp-elements-34 wp-block-paragraph">A waning crescent moon is high in the southeastern sky and the mountains are black silhouettes in the distance. I’ve listened for an hour now—still no bittern. I’m getting cold. If a bittern was calling, I’m pretty sure I would have heard it. Later, I read that bitterns most often call early in the breeding season. Are there bitterns hiding in this marsh, silent now at the end of June?</p>



<h3 class="wp-block-heading">July in the marsh</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/07/12Jul_LakeHelena3-1024x768.jpg" alt="Pre-dawn sky at Lake Helena, July 12." class="wp-image-4370" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/12Jul_LakeHelena3-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/12Jul_LakeHelena3-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/12Jul_LakeHelena3-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/12Jul_LakeHelena3.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Pre-dawn sky at Lake Helena, July 12.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-35 wp-block-paragraph">I return to Lake Helena a week and a half later by kayak, arriving before sunrise on July 12. As I drift slowly through the morning darkness, I’m greeted by a cacophony in the marsh. It’s a roaring buzz, notable from hundreds of yards away. It sounds like the cattails are hosting a convention of miniature chainsaws. But as I get closer, what I find isn’t what I had been expecting, a conglomeration of red-winged blackbirds (<em>Agelaius phoeniceus</em>) or marsh wrens. Instead, it’s a massive group of bank swallows (<em>Riparia riparia</em>), easily a hundred of them, perhaps several times that many.&nbsp;</p>



<p class="has-black-color has-text-color has-link-color wp-elements-36 wp-block-paragraph">Immediately I have a suspicion about what I’m seeing. A nearby bank swallow colony has fledged, I think, and the year’s profusion of fledglings have moved on from the vertical earth bank where they spent the first three or four weeks of their life. As they forage and get ready for migration, the marsh is a safe haven for them to stop and roost for the night.&nbsp;</p>



<h3 class="wp-block-heading">Swallows and nighthawks</h3>



<p class="has-black-color has-text-color has-link-color wp-elements-37 wp-block-paragraph">The pre-dawn sky is pinkish-gray with haze from the Horse Gulch Fire, which started a few days ago in the mountains to the east and has already grown to over 7500 acres. Suddenly, at 5:27 am, the bank swallow flock erupts from the marsh without warning. A swirling cloud of noisy swallows circles over my kayak just long enough for me to snap a photo and estimate that there are at least 250 of them. And then they’re gone, scattering over the lake.</p>


<div class="wp-block-image">

<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="795" src="http://wildwithnature.com/wp-content/uploads/2024/07/coni-1024x795.jpg" alt="Common nighthawk in flight." class="wp-image-4372" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/coni-1024x795.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/coni-300x233.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/coni-768x596.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/coni-1536x1192.jpg 1536w, https://wildwithnature.com/wp-content/uploads/2024/07/coni.jpg 1800w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Common nighthawk in flight.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-38 wp-block-paragraph">As I continue to drift slowly onwards at the edge of the marsh, I think about all of the stories of the birds and other animals that use this place throughout the year. I wonder how many of these stories I haven’t even imagined. On June 19, 2023, <a href="https://ebird.org/checklist/S142140239" target="_blank" rel="noreferrer noopener">Logan Kahle was at Lake Helena in the evening</a> and observed an astounding 680 common nighthawks (<em>Chordeiles minor</em>) flying over the water, where they were presumably foraging.&nbsp;</p>



<p class="has-black-color has-text-color has-link-color wp-elements-39 wp-block-paragraph">“This was a bare minimum estimate, made in a single scan counting by 20s,” he wrote. “I have viewed many amazing nighthawk spectacles over reservoirs in the Great Basin, but this may have been the craziest.”</p>



<h3 class="wp-block-heading">Marsh wrens and marbled godwits</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="889" src="http://wildwithnature.com/wp-content/uploads/2024/07/mawr-1024x889.jpg" alt="Begging juvenile marsh wrens." class="wp-image-4373" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/mawr-1024x889.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/mawr-300x261.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/mawr-768x667.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/mawr.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Begging juvenile marsh wrens.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-40 wp-block-paragraph">Presumably Logan had no idea that evening that he would see such a massive group of nighthawks over the lake. Nor did I set out this morning with any inkling that there would be hundreds of bank swallows roosting in the marsh. Often, the most amazing moments in nature just happen, unexpected.</p>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/07/DSCN8202-1024x768.jpg" alt="Marbled godwits take a drink at the delta." class="wp-image-4382" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8202-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8202-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8202-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8202.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Marbled godwits take a drink at the delta.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-41 wp-block-paragraph">As the sun rises smoky orange over the mountains, I watch a group of three juvenile marsh wrens who give high-pitched begging calls from the edge of the wetland. They still have tufts of downy feathers on their heads, giving me the impression that they only recently got up out of bed and didn’t comb themselves. One of their parents is working overtime to stuff them with insects, hunting diligently for prey among the mud at the edge of the cattail forest.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-42 wp-block-paragraph">At the Prickly Pear Creek delta, the swamp verbena (<em>Verbena hastata</em>) is blooming, rich purple spikes against the green of the marsh. A flock of marbled godwits (<em>Limosa fedoa</em>) is circling low over the sandbar, calling. Finally they land there, gull-sized shorebirds with gently swooping, pale orange bills. They dip their bills in the shallow water and tilt their heads up, drinking.</p>



<h3 class="wp-block-heading">Hot morning at the delta</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/07/DSCN8190-1024x768.jpg" alt="A killdeer perches at the edge of a mudflat." class="wp-image-4381" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8190-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8190-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8190-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8190.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A killdeer perches at the edge of a mudflat.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-43 wp-block-paragraph">The morning sun is fierce now, its intensity increased by the water’s reflection. Most of the shorebirds at the delta today are species that nest here: spotted sandpipers (<em>Actitis macularius</em>), killdeer (<em>Charadrius vociferus</em>), and dozens of Wilson’s phalaropes (<em>Phalaropus tricolor</em>). An impressive flock of 70 American avocets (<em>Recurvirostra americana</em>) flies over but doesn’t land.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-44 wp-block-paragraph">But even though “summer” only began a few weeks ago on the human calendar, and <a href="https://wildwithnature.com/2024/07/01/lake-helena-shorebirds/" target="_blank" rel="noreferrer noopener">the May shorebirds that used these sandbars in their northbound migration towards the Arctic</a> are still a recent memory, the mosaic is already shifting. The marbled godwits—shorebirds which breed in Montana but not, as far as I know, in this urbanized valley—are one of the first hints that fall shorebird migration is already starting. But they’re not alone.</p>



<h3 class="wp-block-heading">Fall shorebird migration</h3>



<p class="has-black-color has-text-color has-link-color wp-elements-45 wp-block-paragraph">As the morning heats up and the roar of Helena Valley traffic echoes through the soundscape, punctuated by the sounds of red-winged blackbirds and a few other species, the shallow water at the delta is full of foraging shorebirds. Here, alongside the Wilson’s phalaropes, I count nine long-billed dowitchers (<em>Limnodromus scolopaceus</em>) and four western sandpipers (<em>Calidris mauri</em>).</p>


<div class="wp-block-image">
<figure class="aligncenter size-large"><img loading="lazy" decoding="async" width="1024" height="839" src="http://wildwithnature.com/wp-content/uploads/2024/07/DSCN8269-1024x839.jpg" alt="Long-billed dowitchers forage in the shallows, with a Wilson's phalarope in the background." class="wp-image-4379" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8269-1024x839.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8269-300x246.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8269-768x629.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8269.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Long-billed dowitchers forage in the shallows, with a Wilson&#8217;s phalarope in the background.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-46 wp-block-paragraph">With these two species, there’s no doubt that these birds are already migrating south. Both breed roughly 2000 miles to the northwest, where wet tundra meets the Arctic Ocean. After a compressed nesting season, by now the adults have already begun their fall migration. The juveniles will wait longer—often another month or more—before they too head south, somehow finding their way across the continent to their wintering grounds without the assistance of their parents. Some western sandpipers will spend the winter as far south as the coast of Peru.</p>

<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="768" height="1024" src="http://wildwithnature.com/wp-content/uploads/2024/07/Sparganium-768x1024.jpg" alt="The marsh of bur-reed." class="wp-image-4378" style="width:400px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/Sparganium-768x1024.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/Sparganium-225x300.jpg 225w, https://wildwithnature.com/wp-content/uploads/2024/07/Sparganium-1152x1536.jpg 1152w, https://wildwithnature.com/wp-content/uploads/2024/07/Sparganium.jpg 1200w" sizes="auto, (max-width: 768px) 100vw, 768px" /><figcaption class="wp-element-caption">The marsh of bur-reed.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-47 wp-block-paragraph">Past the delta with its shorebirds and its usual group of American white pelicans (<em>Pelecanus erythrorhynchos</em>), I decide to give myself time to slow down and notice some more of the life in this place. There are some flies buzzing along a band of sandbar willows (<em>Salix exigua</em>) that divides the lake from part of the marsh as I record a Virginia rail (<em>Rallus limicola</em>) making short, staccato calls from the wetland. Among the incredible diversity of flies in the world, I have no idea what these ones might be, nor do I try to catch one to observe it more closely and find out.&nbsp;</p>



<p class="has-black-color has-text-color has-link-color wp-elements-48 wp-block-paragraph">This patch of marsh is dominated by bur-reed (<em>Sparganium </em>sp.), an expanse of bright green spears pointing skyward, and on the bur-reed flowers I notice some other flies. These ones are bronze-colored with striking yellow bands on the abdomen, suggesting to me that they’re a species of hover fly (family Syrphidae). The flies take off before I can get a photo, but not before I notice that they’re only landing on the small, bright yellow clusters of male bur-reed flowers, which are positioned above the larger, snow-white spheres of female flowers. The hover flies must be finding pollen to feed on, I suspect.</p>



<h3 class="wp-block-heading">Mudflats in miniature</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="815" height="1024" src="http://wildwithnature.com/wp-content/uploads/2024/07/DSCN8294-815x1024.jpg" alt="" class="wp-image-4375" style="width:400px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8294-815x1024.jpg 815w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8294-239x300.jpg 239w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8294-768x965.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8294.jpg 1200w" sizes="auto, (max-width: 815px) 100vw, 815px" /><figcaption class="wp-element-caption">Swamp verbena with a viceroy.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-49 wp-block-paragraph">The morning is getting hotter, and I’m almost ready to turn back. But I paddle just a little bit farther first and stop to photograph the swamp verbena. It’s flowering abundantly here at the edge between lake and marsh, just as it was at the delta. A viceroy (<em>Limenitis archippus</em>), a beautiful <a href="https://wildwithnature.com/2022/07/22/milkweed-monarchs-helena/">monarch-mimicking butterfly</a> whose larvae probably developed on the nearby sandbar willows, is perching on a swamp verbena stem. A second viceroy lands on a mudflat in miniature nearby, flexing its wings. This tiny mudflat has flies, too, but they aren’t the sort that buzz around my microphone to add their voices to a Virginia rail recording. These ones are smaller, delicate, and they glint in the sunlight in tones of metallic copper and green. I suspect they’re some kind of long-legged fly (family Dolichopodidae).</p>



<p class="has-black-color has-text-color has-link-color wp-elements-50 wp-block-paragraph">In a special place in nature such as Lake Helena, the learning is endless. Today, it’s been a huge flock of bank swallows roosting in the pre-dawn marsh. It’s been the shifting kaleidoscope of shorebirds using these mudflats and sandbars alongside massive American white pelicans. And pausing to slow down and take a closer look, I’ve seen something similar in miniature: a viceroy perching alongside dozens of tiny long-legged flies, like the insect analogs of pelicans and shorebirds on a mudflat.</p>

<p class="has-black-color has-text-color has-link-color wp-elements-51 wp-block-paragraph">I’m left feeling grateful for this habitat that supports so much life, from long-legged flies and bur-reed to bank swallows and the occasional massive concentration of foraging nighthawks. I wonder what Lake Helena will teach me next time. And I keep on imagining American bitterns in the marsh. Perhaps, if I come back on an early summer night next year, I’ll find them here, singing.</p>

<p class="has-black-color has-text-color has-link-color wp-elements-86 wp-block-paragraph"><em>Esta historia es la segunda en una serie que se trata de conocer un lugar en la naturaleza con el tiempo y del Lago Helena, un lugar especial para mí en Montana, Estados Unidos. Si no has escuchado <a href="https://wildwithnature.com/2024/07/01/playeros-lago-helena/">la primera parte, puedes empezar ahí</a>… o simplemente ¡empieza aquí en el medio! </em></p>



<p class="has-black-color has-text-color has-link-color wp-elements-87 wp-block-paragraph">Es una noche a finales de junio por un humedal de tules en la región del Rocky Mountain Front de Montana, EU. Hace más de una hora que se puso el sol. Ahora el pálido resplandor crepuscular se ha oscurecido hacia azul sobre la espina dorsal de las montañas. El humedal y el cielo están llenos de los sonidos enfáticos de una docena de agachonas norteamericanas (<em>Gallinago delicata</em>), haciendo un despliegue acústico. Y entonces, desde alguna parte profunda del humedal, volvemos a escuchar otra cosa—aquel extraño sonido, un tragar del aire, <em>¡guam–CATchan! ¡guam–CATchan!</em>—la llamada distintiva del avetoro norteño (<em>Botaurus lentiginosus</em>).&nbsp;</p>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/07/WillowCrRes_sunrise-1024x768.jpg" alt="Pre-dawn along the Rocky Mountain Front." class="wp-image-4367" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/WillowCrRes_sunrise-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/WillowCrRes_sunrise-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/WillowCrRes_sunrise-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/WillowCrRes_sunrise.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">El cielo antes del alba por el Rocky Mountain Front.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-88 wp-block-paragraph">El avetoro norteño es una garza escurridiza de humedales densos, observado con poca frecuencia en Montana. Ésta es la primera vez que alguien ha registrado a un avetoro en este humedal. Seguimos escuchándole llamar por alrededor de media hora más mientras el último brillo del sol desaparece al horizonte. Lo escuchamos otra vez la siguiente mañana en las horas antes del amanecer, empezando cerca de las 4:20 am y siguiendo por aproximadamente 40 minutos. Se calla antes de que salga el sol, un fantasma con alas escondiéndose en el humedal.</p>



<h3 class="wp-block-heading">¿Avetoros por el Lago Helena?</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1-1024x768.jpg" alt="Listening for bitterns before dawn at Lake Helena." class="wp-image-4368" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1-1536x1152.jpg 1536w, https://wildwithnature.com/wp-content/uploads/2024/07/29Jun_LakeHelena1.jpg 2000w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Escuchando por avetoros antes del amanecer por el Lago Helena. </figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-89 wp-block-paragraph"><em>Si un avetoro está habitando acá entre estos tules</em>, me pregunto, <em>¿por qué no por el Lago Helena, 103 kilómetros lejos?</em> Los humedales de tule ahí son aun más extensos. Y así es que cuatro días después vengo llegando al Lago Helena a las cuatro de la mañana para tratar de escuchar avetoros.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-90 wp-block-paragraph">Es una mañana fría y calma mientras madejas de neblina ascienden desde el lago. Estoy parado en botas de pescador al borde del humedal, escuchando atentamente. Tengo mis manos detrás de mis orejas para amplificar los sonidos. Puedo oír los cantos claros de las mascaritas comunes (<em>Geothlypis trichas</em>): <em>guichití, guichití guichití.</em> Los saltaparedes pantaneros (<em>Cistothorus palustris</em>) están parloteando estridentemente. Noto el sonido extraño de una agachona norteamericana en la distancia. De vez en cuando, oigo chapoteos y sonidos que no reconozco desde el humedal—pero no hay ningún avetoro.&nbsp;</p>



<p class="has-black-color has-text-color has-link-color wp-elements-91 wp-block-paragraph">La luna menguante está alto en el cielo al sureste y las montañas son siluetas negras en la distancia. Ya he escuchado por una hora entera—pero no he escuchado nada de un avetoro. Ya tengo frío. Y si un avetoro hubiera llamado, estoy bastante seguro de que lo habría oído. Luego, investigando más sobre los avetoros, leo que suelen llamar más al inicio de la temporada reproductiva. ¿Puede que sí hay avetoros en este humedal, ya silentes al fin de junio?</p>



<h3 class="wp-block-heading">Julio por el humedal</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/07/12Jul_LakeHelena3-1024x768.jpg" alt="Pre-dawn sky at Lake Helena, July 12." class="wp-image-4370" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/12Jul_LakeHelena3-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/12Jul_LakeHelena3-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/12Jul_LakeHelena3-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/12Jul_LakeHelena3.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">El cielo antes del amanecer por el Lago Helena el 12 de julio.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-92 wp-block-paragraph">Con el misterio del avetoro todavía no resuelto, vuelvo al Lago Helena por kayak una semana y media después, llegando antes del amanecer el 12 de julio. Mientras ando a la deriva a través de la oscuridad matutina, me encuentro con una cacofonía en el humedal. Es un zumbido tremendo que se nota a cientos de metros de distancia. Suena como si los tules fueran albergando un congreso de motosierras miniaturas. Pero mientras me acerco más, lo que encuentro no es lo que pensé, una bandada de tordos sargento (<em>Agelaius phoeniceus</em>) o saltaparedes pantaneros. En efecto, es una bandada inmensa de golondrinas ribereñas (<em>Riparia riparia</em>). Fácilmente hay cien de ellas, o tal vez varias cientas.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-93 wp-block-paragraph">Inmediatamente tengo una hipótesis sobre lo que estoy viendo. Los polluelos de una colonia cercana de golondrinas ribereñas han echado plumas, pienso, y la profusión de aves jóvenes ha dejado el barranco de tierra donde pasaron las primeras tres o cuatro semanas de su vida. Mientras forrajean y se preparan para la migración otoñal, el humedal es un lugar de refugio donde pueden pasar la noche.</p>



<h3 class="wp-block-heading">Golondrinas y chotacabras</h3>



<p class="has-black-color has-text-color has-link-color wp-elements-94 wp-block-paragraph">El cielo antes del alba tiene matices de gris y rosa por el humo del Incendio de Horse Gulch. Hace unos días que el incendio brotó en las montañas al este; ya ha crecido hasta más de 3000 hectáreas. De repente, a las 5:27 am, la bandada de golondrinas ribereñas sale del humedal sin aviso. Un remolino de golondrinas ruidosas da vueltas sobre mi kayak por un instante. Apenas logro sacar una foto y estimar que hay por lo menos 250 de ellas. Y entonces se van esparciendo sobre el lago.</p>

<p class="has-black-color has-text-color has-link-color wp-elements-95 wp-block-paragraph">Mientras sigo adelante, andando despacio por el borde del humedal, pienso en todas las historias de las aves y de los otros animales que utilizan este lugar a través del año. Me pregunto cuántas historias podría haber que ni siquiera me he imaginado. Pienso en una de la que aprendí recientemente. El 19 de junio de 2023, <a href="https://ebird.org/checklist/S142140239" target="_blank" rel="noreferrer noopener">Logan Kahle estuvo por el Lago Helena al atardecer</a> cuando observó una increíble concentración de chotacabras zumbones (<em>Chordeiles minor</em>)—680 de ellos—volando sobre el agua, presuntamente forrajeando.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-96 wp-block-paragraph">“Esto fue una estimación mínima, hecha en una sola vista, contándolos de veinte en veinte,” escribió. “He visto varios espectáculos increíbles de los chotacabras zumbones sobre embalses en la Gran Cuenca, pero puede que esto fue lo más increíble.”</p>

</div>


<p class="has-black-color has-text-color has-link-color wp-elements-97 wp-block-paragraph">Me imagino que Logan no tenía ninguna idea de que fuera a ver un grupo tan enorme de chotacabras sobre el lago aquel atardecer. Ni tampoco salí yo esta mañana con ninguna sospecha de que hubiera cientas de golondrinas posándose en el humedal. A menudo, los momentos más alucinantes en la naturaleza simplemente llegan, inesperados. </p>

</div>


<p class="has-black-color has-text-color has-link-color wp-elements-98 wp-block-paragraph">Mientras el sol sale bañado en humo, anaranjado sobre las montañas, observo un grupo de tres saltaparedes pantaneros juveniles que están mendigando con llamadas agudas desde el borde del humedal. Todavía tienen penachos de plumas suaves en la cabeza, dejando la impresión de que recién se levantaron y no se peinaron. Uno de sus padres está trabajando duro para atiborrarlos con insectos, cazando invertebrados atentamente sobre el barro al borde de este bosque de tules.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-99 wp-block-paragraph">Por el delta del Arroyo Prickly Pear, la verbena (<em>Verbena hastata</em>) está floreciendo, espigas de púrpura real contra el verde del humedal. Una bandada de picopandos canelos (<em>Limosa fedoa</em>) está volando cerca, llamando y dando vueltas a baja altura sobre el arenal. Finalmente aterrizan ahí, playeros del tamaño de una gaviota con picos anaranjados y ligeramente curvados hacia arriba. Meten los picos en el agua poco profunda e inclinan las cabezas hacia arriba, bebiendo.</p>



<h3 class="wp-block-heading">Una mañana calurosa por el delta</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/07/DSCN8190-1024x768.jpg" alt="A killdeer perches at the edge of a mudflat." class="wp-image-4381" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8190-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8190-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8190-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8190.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A killdeer perches at the edge of a mudflat.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-100 wp-block-paragraph">El sol de la mañana ya se ha puesto feroz, su intensidad aumentado por el reflejo del agua. La mayoría de los playeros que están por el delta hoy son especies que anidaron aquí: playeros alzacolita (<em>Actitis macularius</em>), chorlos tildío (<em>Charadrius vociferus</em>) y docenas de falaropos pico largo (<em>Phalaropus tricolor</em>). Una bandada impresionante de 70 avocetas americanas (<em>Recurvirostra americana</em>) vuela por encima pero no aterriza.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-101 wp-block-paragraph">Lo que se considera &#8220;el verano&#8221; sólo empezó hace unas semanas en el calendario humano. Los playeros de mayo <a href="https://wildwithnature.com/2024/07/01/playeros-lago-helena/" target="_blank" rel="noreferrer noopener">que usaron estos arenales en su migración hacia el norte</a> aún son una memoria reciente, pero el mosaico ya está cambiando. Los picopandos canelos—playeros que anidan en Montana pero no este valle urbanizado, hasta donde sé—son una de las primeras pistas que la migración otoñal de los playeros ya está comenzando. Pero no son la única pista.</p>



<h3 class="wp-block-heading">La migración otoñal de los playeros</h3>



<p class="has-black-color has-text-color has-link-color wp-elements-102 wp-block-paragraph">Mientras la mañana se pone más calurosa y el rugido del tráfico hace eco por el valle, intercalado con los sonidos de los tordos sargentos y unas especies más, veo que el agua poco profunda del delta está llena de playeros que están forrajeando. Aquí, al lado de una gran bandada de falaropos pico largo, cuento nueve costureros pico largo (<em>Limnodromus scolopaceus</em>) y cuatro playeros occidentales (<em>Calidris mauri</em>).</p>


<div class="wp-block-image">
<figure class="aligncenter size-large"><img loading="lazy" decoding="async" width="1024" height="839" src="http://wildwithnature.com/wp-content/uploads/2024/07/DSCN8269-1024x839.jpg" alt="Long-billed dowitchers forage in the shallows, with a Wilson's phalarope in the background." class="wp-image-4379" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8269-1024x839.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8269-300x246.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8269-768x629.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8269.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Los costureros pico largo forrajean en el bajío con un falaropo pico largo en el fondo. </figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-103 wp-block-paragraph">Respecto a estas dos especies, no hay ninguna duda de que ya están migrando hacia el sur. Las dos anidan aproximadamente 3500 kilómetros al noroeste, donde la tundra húmeda del Ártico limita con el Océano Ártico. Después de una temporada reproductiva condensada, los adultos ya han empezado su migración otoñal. Los juveniles esperarán hasta más tarde—típicamente por otro mes o más—antes de volar hacia el sur también. De alguna manera van a navegar a través del continente hacia sus tierras invernales sin ninguna ayuda de sus padres. Algunos playeros occidentales seguirán en la migración hasta llegar a la costa del Perú y allá pasar el invierno.</p>

</div>


<p class="has-black-color has-text-color has-link-color wp-elements-104 wp-block-paragraph">Ya he pasado por el delta con sus playeros y el grupo usual de pelícanos blancos americanos (<em>Pelecanus erythrorhynchos</em>). Ahora decido darme tiempo para pausar y notar un poco más de la vida de este lugar. Me doy cuenta de algunas moscas que están zumbando a lo largo de una franja de sauces (<em>Salix exigua</em>) que forma la divisoria entre el lago y una parte del humedal mientras grabo a un rascón cara gris (<em>Rallus limicola</em>). El rascón está dando llamadas cortas e interrumpidas desde el humedal. No tengo ni idea cuáles moscas serían éstas, entre la diversidad increíble de moscas en el mundo. Tampoco trato de capturarlas para observarlas mejor.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-105 wp-block-paragraph">Este parche del humedal está dominado por <em>Sparganium</em>, una planta relacionada al tule. Se parece a una extensión de lanzas verdes puntadas hacia el cielo, y sobre las flores del <em>Sparganium</em> noto algunas otras moscas. Éstas son de color bronce con llamativas franjas amarillas en el abdomen, lo que me sugiere que sean una especie de sírfido (moscas de la familia Syrphidae). Se echan a volar antes de que pueda tomar una foto. Pero ya me he dado cuenta de que sólo están aterrizando en las bolas pequeñas y amarillas de las flores masculinas, las cuales están arriba de las bolas más grandes y blancas de las flores femeninas. Sospecho que los sírfidos están alimentándose de polen.</p>



<h3 class="wp-block-heading">Barrizales en miniatura</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="815" height="1024" src="http://wildwithnature.com/wp-content/uploads/2024/07/DSCN8294-815x1024.jpg" alt="" class="wp-image-4375" style="width:400px" srcset="https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8294-815x1024.jpg 815w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8294-239x300.jpg 239w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8294-768x965.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/07/DSCN8294.jpg 1200w" sizes="auto, (max-width: 815px) 100vw, 815px" /><figcaption class="wp-element-caption">Una mariposa virrey se percha en la verbena.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-106 wp-block-paragraph">Ya está haciendo bastante calor y casi estoy listo para volver. Pero primero remo adelante un poquito más y me detengo para tomar fotos de la verbena. Está floreciendo en abundancia aquí al límite entre el lago y el humedal, así como estaba floreciendo también por el delta. Una mariposa virrey (<em>Limenitis archippus</em>), un insecto hermoso que se parece a la mariposa monarca, está perchada en un tallo de verbena. Sus larvas probablemente se alimentaron de los sauces nativos cercanos.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-107 wp-block-paragraph">Una segunda mariposa virrey aterriza sobre un barrizal en miniatura cerca de la verbena, flexionando sus alas. Este barrizal pequeño tiene moscas, también, pero no son el tipo que zumban por mi micrófono para añadir sus voces a la grabación de un rascón cara gris. Éstas son más pequeñas y delicadas. Brillan en la luz del sol con tonalidades de cobre y de verde metálico. Sospecho que son algún tipo de mosca de patas largas (la familia Dolichopodidae).</p>



<p class="has-black-color has-text-color has-link-color wp-elements-108 wp-block-paragraph">En un lugar especial en la naturaleza tal como el Lago Helena, el deleite de conocer sigue sin fin. Hoy ha sido una bandada enorme de golondrinas ribereñas posándose en el humedal antes del amanecer. Ha sido el caleidoscopio variable de los playeros que usan estos barrizales y arenales al lado de los masivos pelícanos blancos americanos. Y cuando me detuve para mirar más minuciosamente, vi algo similar en miniatura: una mariposa virrey posándose al lado de docenas de moscas de patas largas en un barrizal pequeño, como los insectos homólogos a los pelícanos y playeros.</p>

Me pregunto qué el Lago Helena me va a enseñar la próxima vez. Y sigo imaginando avetoros norteños en el humedal. A lo mejor, si vuelvo una noche al comienzo del verano que viene, más temprano en la estación reproductiva, voy a encontrarlos cantando aquí.</p>

</div>


<p class="has-black-color has-text-color has-link-color wp-elements-141 wp-block-paragraph">Una lluvia ligera cayó durante la noche, y la parte occidental del Lago Helena está envuelta en una neblina gris y suave mientras el sol amanece sobre las Montañas Big Belt. Desde nuestros kayaks, aparece como una bola luminosa filtrada por las nubes. Las voces de las aves están silenciadas. Casi los únicos sonidos, aparte del ruido distante del tráfico en la carretera, son el chapoteo de mi remo y el golpeteo rítmico de la manija en el extremo de mi kayak.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-142 wp-block-paragraph">Estoy siguiendo a mi mentor y amigo, el biólogo Grant Hokit, a través de la neblina, remando hacia el delta donde el Arroyo Prickly Pear desemboca en el Lago Helena. Durante esta temporada de la migración primaveral, los arenales y barrizales ahí son un lugar popular para los pájaros playeros. Varios playeros hacen escala aquí rumbo a un verano mucho más al norte, por la tundra del Ártico.</p>



<h3 class="wp-block-heading">El hábitat por el Lago Helena</h3>

<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/05/2-LH-2023-1024x768.jpg" alt="Riparian habitat along the edge of Lake Helena." class="wp-image-4264" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/2-LH-2023-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/2-LH-2023-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/2-LH-2023-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/2-LH-2023.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Hábitat ribereño en el borde del Lago Helena.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-143 wp-block-paragraph">Estoy en Helena, Montana, EU este verano, trabajando con Grant para estudiar la ecología de enfermedades en garrapatas y zancudos. Y durante mañanas como ésta, cuando no estamos trabajando, el Lago Helena—uno de los lugares más cercanos para observar una gran diversidad de aves y otros animales—nos atrae como un imán. El lago poco profundo, que mide 4.4 km de un extremo al otro, está rodeado en dos lados por estanques más pequeños y humedales extensos de tules (<em>Typha latifolia</em>) y cárices (<em>Carex </em>spp.).</p>



<p class="has-black-color has-text-color has-link-color wp-elements-144 wp-block-paragraph">Y donde el Arroyo Prickly Pear desemboca en el lago, no sólo es un buen hábitat para playeros migratorios. También crece una franja amplia de sauces nativos (<em>Salix amygdaloides</em>) con un sotobosque de rosas (<em>Rosa woodsii</em>), grosellas (<em>Ribes aureum</em>) y más sauces arbustivos (<em>Salix</em> spp.)—o sea, un excelente hábitat ribereño para un montón de animales, desde chipes amarillos (<em>Setophaga petechia</em>) hasta venados cola blanca (<em>Odocoileus virginianus</em>).&nbsp;</p>



<h3 class="wp-block-heading">Visitando un lugar especial</h3>

<p class="has-black-color has-text-color has-link-color wp-elements-145 wp-block-paragraph">Para mí como naturalista, una de mis cosas favoritas en la vida es pasar tiempo en hábitats increíbles para la vida silvestre, como el Lago Helena y sus humedales circundantes. En cualquier parte del mundo donde yo esté viviendo, intento conocer a un lugar así, un lugar en la naturaleza que esté lo más cerca posible a mi domicilio. Cuando lo visito, traigo un refrigerio, ropa para cualquier cambio del clima y mucha agua. Vengo con la intención de estar por unas horas o más. A veces me siento tan contento aquí que termino pasando todo el día.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-146 wp-block-paragraph">Me gusta ir despacio. A menudo, sentar en silencio—o ir a la deriva en un kayak—es una manera increíble de acercarnos a las aves y a los otros animales y aprender de sus vidas sin molestarlos. Y después de empezar a conocer a un lugar como éste, me encanta regresar tan frecuentemente como pueda, conociendo cómo sus humores y patrones cambian por los días y por las temporadas del año. Es algo que me da un sentido de pertenecer a la tierra. Me da esperanza ver la resistencia y la diversidad de la vida. También me da un deseo fuerte de proteger y cuidar a estas áreas especiales.</p>



<h3 class="wp-block-heading">Contando historias del Lago Helena</h3>

</div>


<p class="has-black-color has-text-color has-link-color wp-elements-147 wp-block-paragraph">El Lago Helena, si lo visito en mayo por kayak, es uno de los lugares que parece casi gritarme para contar historias sobre él. Así fue cuando lo visité la primavera pasada, el 16 de mayo de 2023, también durante una mañana neblinosa. Anduve despacio por la neblina fría, cuidadosamente para no molestar a un grupo de cisnes trompeteros (<em>Cygnus buccinator</em>) que nadaban cerca del borde del humedal, conversando entre sí en voz baja.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-148 wp-block-paragraph">Y ahora, un año después, el humedal y el lago parecen estarme llamando otra vez para compartir sus historias. Este retrato, de mi mañana en el Lago Helena el 15 de mayo de 2024, será el primero de unos cuantos. Mientras yo vuelve a visitar este lugar durante este verano, voy a preparar una serie de historias siguiendo el progreso de las estaciones acá. Y sin importar si el Lago Helena está cerca de ti o si está lejos, espero que estos retratos de vayan a inspirar. Mientras leas o escuches, te animo a pensar en tus propios lugares especiales en la naturaleza—o si no tienes un lugar así en tu vida, a lo mejor puedes buscarlo. ¿Qué similitudes hay entre tu lugar especial y el Lago Helena? ¿Qué es diferente?</p>



<h3 class="wp-block-heading">Los sonidos del humedal</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="845" src="http://wildwithnature.com/wp-content/uploads/2024/05/5-LH-Sora-Sept-2022-1024x845.jpg" alt="A sora wades at the edge of a cattail marsh, September 2022." class="wp-image-4267" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/5-LH-Sora-Sept-2022-1024x845.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/5-LH-Sora-Sept-2022-300x248.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/5-LH-Sora-Sept-2022-768x634.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/5-LH-Sora-Sept-2022.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Una polluela sora vadea al borde de un humedal de tules en septiembre de 2022. </figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-149 wp-block-paragraph">He dejado de remar por un tiempo, y escucho mientras mi kayak sigue a la deriva. Sobre el murmullo del tráfico distante, la música del humedal al oeste me alcanza a través de velos de neblina. Puedo oír los trinos estridentes y mecánicos de los saltaparedes pantaneros (<em>Cistothorus palustris</em>). Una polluela sora (<em>Porzana carolina</em>)—un ave pequeña y sigilosa de los tules—repite su nombre una y otra vez: <em>¿So–rá? ¿So–rá?</em></p>



<p class="has-black-color has-text-color has-link-color wp-elements-150 wp-block-paragraph">Puedo escuchar el canto <em>conca–riiii</em> de los tordos sargentos (<em>Agelaius phoeniceus</em>) y varias otras voces familiares en la distancia. Las grullas grises (<em>Antigone canadensis</em>) empiezan a dar sus llamadas lindas y graves. Me pregunto si están cerca del nido que encontramos hace unos días, una plataforma camuflada de tules al borde del agua.</p>



<h3 class="wp-block-heading">Pelícanos blancos americanos y avocetas americanas</h3>

</div>


<p class="has-black-color has-text-color has-link-color wp-elements-151 wp-block-paragraph">Una bandada de pelícanos blancos americanos (<em>Pelecanus erythrorhynchos</em>) aparece adelante de nosotros a través de la niebla, mostrándonos la ubicación del arenal principal del delta. Conforme nos acercamos, casi dejamos de remar y cambiamos nuestro rumbo para mantener la distancia y pasar por los pelícanos, respetando su espacio. Con el tiempo vamos a acercarnos más a una parte del arenal, pero vamos a hacerlo poco a poco, tranquilos, atentos al comportamiento de las aves. Así vamos a poder observar los playeros forrajeando sólo unos metros de nuestros kayaks, sin preocupación. Los pelícanos siempre requieren más espacio, pero ellos también van a permitirnos acercarnos hasta cierto punto. Como siempre con la observación de la vida silvestre, nuestra primera prioridad es respetar a los animales y minimizar cualquier molestia a ellos.</p>

</div>


<p class="has-black-color has-text-color has-link-color wp-elements-152 wp-block-paragraph">Los sonidos del humedal se escuchan más fuertes ya, y una avoceta americana (<em>Recurvirostra americana</em>) está llamando, un <em>¡pik! ¡pik! ¡pik! </em>insistente mientras ella vadea por el agua poco profunda cerca del arenal. La avoceta está cazando a tientas, arrastrando el pico por el agua para buscar invertebrados. Las avocetas americanas se han observado por todo el verano por este lago y aparentemente anidan acá, aunque registros definitivos de anidación en este sitio son escasos.</p>



<h3 class="wp-block-heading">Playeros en el arenal</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1200" height="900" src="http://wildwithnature.com/wp-content/uploads/2024/05/8-1024x768.jpg" alt="The black-bellied plover." class="wp-image-4270" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/8-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/8-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/8-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/8.jpg 1200w" sizes="auto, (max-width: 1200px) 100vw, 1200px" /><figcaption class="wp-element-caption">El chorlo gris.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-153 wp-block-paragraph">La niebla se ha levantado, retrocediendo al sur donde un banco denso de nubes todavía está cubriendo las áreas aguas arriba por el Arroyo Prickly Pear. Una manada de gaviotas pico anillado vuela sobre nosotros, llamando fuertemente. De vez en cuando seguimos escuchando la avoceta americana. Y ahora un chorlo gris (<em>Pluvialis squatarola</em>) empieza a llamar, un <em>¿piuiii? </em>claro e insistente que sigue repitiéndose. El chorlo, un ave hermosa en su plumaje reproductivo de negro y blanco, es uno de aquellos playeros que están rumbo al Ártico. Allá va a anidar en un paisaje intensamente estacional que nunca he visitado, esparcido con sauces diminutos y brezos.</p>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="855" src="http://wildwithnature.com/wp-content/uploads/2024/05/9-1024x855.jpg" alt="A least sandpiper forages close to our kayaks." class="wp-image-4271" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/9-1024x855.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/9-300x251.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/9-768x641.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/9.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Un playero diminuto forrajea cerca de nuestros kayaks. </figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-154 wp-block-paragraph">Ya hemos llegado al borde del arenal, todavía dando mucho espacio a los pelícanos. Un grupo de playeros diminutos (<em>Calidris minutilla</em>) se ha acercado a nosotros y está forrajeando dentro de unos metros de nuestros kayaks. De vez en cuando parlotean con exuberancia mientras agarran invertebrados de la arena. Como el chorlo gris—que sigue silbando en el fondo—los playeros diminutos son migrantes rumbo al norte. Van a anidar a través de una amplia variedad de praderas boreales y árticas, llenas de brezos y cárices.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-155 wp-block-paragraph">De repente el chorlo gris se echa a volar, silbando fuertemente mientras nos pasa volando. Un chorlo semipalmeado (<em>Chardrius semipalmatus</em>)—otro migrante rumbo al norte que estaba forrajeando cerca—sigue al chorlo gris, dando unas llamadas chirriantes. </p>



<h3 class="wp-block-heading">Desde los barrizales hasta el humedal</h3>

</div>


<p class="has-black-color has-text-color has-link-color wp-elements-156 wp-block-paragraph">Ya hemos estado sentados en silencio por un buen tiempo, observando el arenal y los bajos y barrizales adyacentes. Cuánto tiempo, no sé—¿una hora? ¿Dos? Entre los playeros migrantes que están descansado y forrajeando aquí, encontramos dos playeros zancones (<em>Calidris himantopus</em>), aves grises con patas largas que se alimentan metódicamente en agua tan profunda como pueden alcanzar sus patas. Ésta es la primera vez que alguien ha registrado la presencia de esta especie por el Lago Helena durante la primavera, y estoy emocionado que hayamos podido anotar esta observación. Cada registro de las aves migratorias o de todo tipo de vida silvestre aumenta nuestro conocimiento de este lugar, ayudándonos a entender su importancia y protegerlo.</p>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/05/11-LH-1024x768.jpg" alt="Habitat at the edge of the marsh." class="wp-image-4273" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/11-LH-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/11-LH-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/11-LH-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/11-LH.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">El hábitat al borde del humedal.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-157 wp-block-paragraph">Después de un rato más, remo adelante hacia el borde del humedal. El hábitat aquí es increíble—y la oleada de canto que ahora me rodea lo refleja. Estanques poco profundos con tules y cárices se mezclan con bosquecillos densos de sauces. Puedo reconocer las voces individuales en el coro de las aves: saltapared pantanero, rascón cara gris (<em>Rallus limicola</em>), agachona norteamericana  (<em>Gallinago delicata</em>), tordo cabeza café (<em>Molothrus ater</em>), mascarita común (<em>Geothlypis trichas</em>), tordo sargento, chipe amarillo (<em>Setophaga petechia</em>), ganso canadiense mayor (<em>Branta canadensis</em>) y huilota común (<em>Zenaida macroura</em>).</p>



<h3 class="wp-block-heading">Saltaparedes pantaneros y polluelas soras</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/05/12-MAWR-Apr-2020-1024x768.jpg" alt="A marsh wren, photographed in April 2020." class="wp-image-4274" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/12-MAWR-Apr-2020-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/12-MAWR-Apr-2020-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/12-MAWR-Apr-2020-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/12-MAWR-Apr-2020.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Un saltapared pantanero, fotografiado en abril de 2020. </figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-158 wp-block-paragraph">Pero la voz más aparente es la del saltapared pantanero, cantando sus trinos mecánicos y disonantes que sólo saltaparedes pantaneros machos cantan. Hace dos días que observé otro macho recolectando la pelusa del tule y cargándola hacia su nido en forma de pelota, tejida entre los tallos de tule del año pasado. Mientras los playeros están haciendo escala aquí rumbo al corto verano ártico, muchas de las aves reproductivas del humedal ya están más adelantadas en su ciclo estacional.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-159 wp-block-paragraph">Desde un parche denso de tules al lado del agua abierta, una polluela sora empieza a llamar otra vez, muy cerca de mí. <em>¿So–ra? ¿So–ra? </em>llena mis oídos, esta voz típica del humedal del Lago Helena. Más en la distancia un rascón cara gris, otra ave reservada del humedal, está dando sus llamadas <em>gidic, gidic, gidic</em>.</p>

<p class="has-black-color has-text-color has-link-color wp-elements-160 wp-block-paragraph">El Lago Helena está calificado como un Área Importante Para Aves por <a href="https://www.birdlife.org/" target="_blank" rel="noreferrer noopener">BirdLife International</a>: un sitio reconocido por su importancia por la conservación de aves. Hoy, al estar aquí, esta calificación no es ninguna sorpresa. Mientras remos de vuelta y pasamos por el delta, una brisa suave ha empezado desde el este, empujando olas pequeñas que se estrellan contra el arenal. Los pelícanos todavía están ahí, perchados junto con cuatro especies de gaviotas y un grupo mezclado de charranes de Forster (<em>Sterna forsteri</em>) y charranes comunes (<em>Sterna hirundo</em>).&nbsp;</p>



<p class="has-black-color has-text-color has-link-color wp-elements-161 wp-block-paragraph">Hemos pasado casi seis horas aquí esta mañana, y sería fácil quedarnos más tiempo aún. Pero todavía hay trabajo de oficina por hacer, y el viento nos está sugiriendo que pudiera ser la hora de irnos. Pero mientras me siente en la oficina, escribiendo y editando este retrato, sé que el Lago Helena sigue aquí. Sé que voy a regresar a visitarlo una y otra vez. Y cada vez que lo visito, me va a recordar de qué tan abundante puede ser la vida y me va a enseñar algo nuevo. Y espero que, por cualquier parte del mundo que estés, haya un lugar especial cerca de ti también.</p>

<p class="has-black-color has-text-color has-link-color wp-elements-190 wp-block-paragraph"><strong>May 15, 2024</strong></p>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/05/1-LH-1024x768.jpg" alt="The sun rises through the fog over Lake Helena." class="wp-image-4262" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/1-LH-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/1-LH-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/1-LH-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/1-LH.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">The sun rises through the fog over Lake Helena.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-191 wp-block-paragraph">A light rain fell during the night, and the west end of Lake Helena is wrapped in a gentle gray fog as the sun rises above the Big Belt Mountains. From our kayaks, it appears as a luminous ball filtered through the clouds. The voices of the birds are hushed. Almost the only sounds, besides the distant traffic noise from the interstate, are the splashing of my paddle and the rhythmic banging of the carrying handle at the end of my kayak.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-192 wp-block-paragraph">I’m following my mentor, fellow biologist, and friend Grant Hokit through the fog, pointed towards the delta where Prickly Pear Creek empties into Lake Helena. During this season of spring migration, the sandbars and mudflats at the mouth of the creek are a local hotspot for shorebirds, many of them heading towards a summer much farther north on the Arctic tundra.&nbsp;</p>



<h3 class="wp-block-heading">Wildlife habitat at Lake Helena</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/05/2-LH-2023-1024x768.jpg" alt="Riparian habitat along the edge of Lake Helena." class="wp-image-4264" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/2-LH-2023-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/2-LH-2023-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/2-LH-2023-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/2-LH-2023.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Riparian habitat along the edge of Lake Helena.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-193 wp-block-paragraph">I’m in Helena, Montana this summer, working with Grant to study disease ecology in ticks and mosquitoes. And on mornings like this one, when we aren’t working, Lake Helena—one of our closest local spots to observe a great diversity of birds and other wildlife—is drawing us like a magnet. The shallow lake, which spans over two and a half miles from end to end, is surrounded on two sides by smaller ponds and extensive wetlands of cattails and sedges.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-194 wp-block-paragraph">And where Prickly Pear Creek spills into it, there’s not only good habitat for migratory shorebirds but also a broad band of peachleaf willows (<em>Salix amygdaloides</em>) with an understory of Wood’s rose (<em>Rosa woodsii</em>), golden currant (<em>Ribes aureum</em>), and other shrubby willow species (<em>Salix</em> spp.)—in short, an excellent riparian habitat for animals ranging from yellow warblers (<em>Setophaga petechia</em>) to white-tailed deer (<em>Odocoileus virginianus</em>).&nbsp;</p>



<h3 class="wp-block-heading">Visiting a special place</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/05/3-LH-1024x768.jpg" alt="Grant Hokit kayaks ahead of me across Lake Helena through the mist." class="wp-image-4265" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/3-LH-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/3-LH-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/3-LH-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/3-LH.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Grant Hokit kayaks ahead of me across Lake Helena through the mist.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-195 wp-block-paragraph">As a naturalist, one of my favorite things in life is spending time in incredible wildlife habitats like Lake Helena and its surrounding wetlands. Wherever I live, I try to find at least one place like this, as close to home as I can. Whenever I visit, I bring snacks, layers, and plenty of water and I plan to spend at least a few hours. Sometimes I’m so happy to be out here that I end up spending the whole day. </p>



<p class="has-black-color has-text-color has-link-color wp-elements-196 wp-block-paragraph">I like to go slowly. Often, sitting quietly—or drifting slowly in a kayak—is an amazing way to get close to birds and other animals and to learn about their lives without disturbing them. And after I’ve started to get to know a place like this, I love returning to it whenever I can, seeing how its moods and patterns change from day to day and from season to season. It’s something that gives me a sense of belonging on the earth, a sense of hope for the resilience and diversity of life, and a compelling desire to protect and nurture these special areas.</p>



<h3 class="wp-block-heading">Telling stories of Lake Helena</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/05/4-LH-1024x768.jpg" alt="Trumpeter swans along the shore of Lake Helena in May 2023." class="wp-image-4266" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/4-LH-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/4-LH-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/4-LH-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/4-LH.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Trumpeter swans along the shore of Lake Helena in May 2023.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-197 wp-block-paragraph">Lake Helena is one of those places that, when I come here in May by kayak, seems to shout to me to tell stories about it. That’s how it was when I went there last spring, on May 16, 2023, a foggy morning as well. I drifted slowly through the chilly mist, being careful not to disturb the group of trumpeter swans (<em>Cygnus buccinator</em>) who were paddling near the edge of the marsh, talking quietly among themselves.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-198 wp-block-paragraph">And now, a year later, the marsh and lake seem to be calling to me once again to share their story. This portrait, from my morning at Lake Helena on May 15, 2024, will be the first of several. As I visit this place again throughout the summer, I’ll be preparing a series of stories following the seasonal progression here. And whether Lake Helena is near to you or far away, I hope that these portraits will inspire you. As you read or listen, I encourage you to think about your local special places in nature—or if you don’t have a spot like this in your life, to see if you can find one. What is similar between Lake Helena and your special place? What is different?</p>



<h3 class="wp-block-heading">The soundscape of the marsh</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="845" src="http://wildwithnature.com/wp-content/uploads/2024/05/5-LH-Sora-Sept-2022-1024x845.jpg" alt="A sora wades at the edge of a cattail marsh, September 2022." class="wp-image-4267" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/5-LH-Sora-Sept-2022-1024x845.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/5-LH-Sora-Sept-2022-300x248.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/5-LH-Sora-Sept-2022-768x634.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/5-LH-Sora-Sept-2022.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A sora wades at the edge of a cattail marsh, September 2022.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-199 wp-block-paragraph">I’ve stopped paddling for a little while, listening as my kayak drifts. Over the constant rumble of distant traffic, the music of the marsh soundscape to the west reaches me through shrouds of mist. I can hear the harsh, mechanical trills of the marsh wrens (<em>Cistothorus palustris</em>). A sora (<em>Porzana carolina</em>)—a small, secretive bird of the cattails—calls its name over and over: <em>so–ra? so–ra?</em> </p>



<p class="has-black-color has-text-color has-link-color wp-elements-200 wp-block-paragraph">I can hear the <em>konk–a–ree</em> song of the red-winged blackbirds (<em>Agelaius phoeniceus</em>) and so many other familiar, fainter voices. And then the sandhill cranes (<em>Antigone canadensis</em>) start their beautiful, deep-throated calling. I wonder if they’re near the nest we found a few days ago, a camouflaged platform of cattails at the water’s edge.</p>



<h3 class="wp-block-heading">American white pelicans and American avocets</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/05/6-LH-1024x768.jpg" alt="A water tower gleams through the dissipating fog behind the American white pelicans on the sandbar." class="wp-image-4268" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/6-LH-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/6-LH-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/6-LH-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/6-LH.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A water tower gleams through the dissipating fog behind the American white pelicans on the sandbar.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-201 wp-block-paragraph">A shoal of American white pelicans (<em>Pelecanus erythrorhynchos</em>) looms ahead of us through the cool mist, showing us the location of the main sandbar of the delta. As our kayaks glide closer, we slow our paddling drastically and change course to keep our distance and float past, respecting the pelicans’ space. Eventually we’ll get closer to a portion of the sandbar, but we’ll do so slowly, quietly, attentive to the behavior of the birds. In this way, we’ve been able to watch sandpipers foraging within yards of our boats, unconcerned. The pelicans always require more space than that, but they too allow us to approach relatively close. As always with wildlife observation, our number one priority is to respect the animals and keep any disturbance to a minimum.</p>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="844" src="http://wildwithnature.com/wp-content/uploads/2024/05/7-LH-1024x844.jpg" alt="An American avocet feeds in the shallows at the delta." class="wp-image-4269" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/7-LH-1024x844.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/7-LH-300x247.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/7-LH-768x633.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/7-LH.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">An American avocet feeds in the shallows at the delta.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-202 wp-block-paragraph">The marsh sounds are louder now, and an American avocet (<em>Recurvirostra americana</em>) is calling, an insistent <em>peek! peek! peek!</em> as it wades through the shallow water near the sandbar. The avocet is hunting by feel, sweeping its bill through the water in search of invertebrates. American avocets have been observed throughout the summer at Lake Helena and apparently nest here, though definitive records of avocets breeding at this site are scarce.</p>



<h3 class="wp-block-heading">Shorebirds at the sandbar</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1200" height="900" src="http://wildwithnature.com/wp-content/uploads/2024/05/8-1024x768.jpg" alt="The black-bellied plover." class="wp-image-4270" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/8-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/8-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/8-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/8.jpg 1200w" sizes="auto, (max-width: 1200px) 100vw, 1200px" /><figcaption class="wp-element-caption">The black-bellied plover.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-203 wp-block-paragraph">The fog has lifted, receding south of us where a dense cloudbank is still covering the areas upstream along Prickly Pear Creek. A flock of ring-billed gulls flies right over us, calling loudly. From time to time we hear the American avocet again. And then a black-bellied plover (<em>Pluvialis squatarola</em>) begins calling, a clear and insistent <em>peeowee?</em> that it repeats, over and over. The plover, a gorgeous bird in its black-and-white breeding plumage, is one of those shorebirds that’s bound for the Arctic, where it will nest in an intensely seasonal landscape I’ve never visited, dotted with dwarf willows and heathers.&nbsp;</p>

</div>


<p class="has-black-color has-text-color has-link-color wp-elements-204 wp-block-paragraph">By now we’ve drifted in to the edge of the sandbar, still giving the pelicans plenty of space. A group of tiny least sandpipers (<em>Calidris minutilla</em>) has approached us and is foraging within a few feet of our kayaks. From time to time they chatter exuberantly as they pick invertebrates from the sand. Like the black-bellied plover—which is still whistling in the background—the least sandpipers are northbound migrants. They’ll nest across a wide range of boreal and arctic meadows, filled with sedge and heather.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-205 wp-block-paragraph">Suddenly the black-bellied plover launches into the air, whistling loudly as he flies past. A semipalmated plover—another northbound migrant that was feeding close to us—follows the black-bellied plover, giving a few creaky sounds.&nbsp;</p>



<h3 class="wp-block-heading">From the mudflats to the marsh</h3>

</div>


<p class="has-black-color has-text-color has-link-color wp-elements-206 wp-block-paragraph">We&#8217;ve sat quietly for a long time observing the sandbar and the adjacent mudflats and shallows. How long, I don’t know—one hour? Two? Among the migrating shorebirds resting and foraging here today, we find two stilt sandpipers (<em>Calidris himantopus</em>), long-legged gray birds that feed methodically in water as deep as they can wade. It’s the first time this species has been recorded at Lake Helena in the spring, and I’m pleased that we can make this observation. Each record of migratory birds and other wildlife adds to our knowledge of this place, helping us understand how important it is and protect it.</p>

</div>


<p class="has-black-color has-text-color has-link-color wp-elements-207 wp-block-paragraph">Eventually, I paddle on towards the edge of the marsh. The habitat here is incredible—and the swell of birdsong that surrounds me now reflects that. Shallow pools with cattails and sedges mix with dense, bushy willow thickets. I can recognize the individual voices in the chorus of birds: marsh wren, Virginia rail (<em>Rallus limicola</em>), Wilson’s snipe (<em>Gallinago delicata</em>), brown-headed cowbird (<em>Molothrus ater</em>), common yellowthroat (<em>Geothlypis trichas</em>), red-winged blackbird, yellow warbler (<em>Setophaga petechia</em>), Canada goose (<em>Branta canadensis</em>), mourning dove (<em>Zenaida macroura</em>). </p>



<h3 class="wp-block-heading">Marsh wrens and soras</h3>

<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2024/05/12-MAWR-Apr-2020-1024x768.jpg" alt="A marsh wren, photographed in April 2020." class="wp-image-4274" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2024/05/12-MAWR-Apr-2020-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2024/05/12-MAWR-Apr-2020-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2024/05/12-MAWR-Apr-2020-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2024/05/12-MAWR-Apr-2020.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A marsh wren, photographed in April 2020.</figcaption></figure>
</div>


<p class="has-black-color has-text-color has-link-color wp-elements-208 wp-block-paragraph">But the most apparent is the marsh wren, singing his jarring, mechanical trills that only male marsh wrens sing. Two days ago, I watched a different male gathering cattail fluff and carrying it to his ball-shaped nest, woven among last year’s cattail stems. As the shorebirds are stopping over here on their way to the short Arctic summer, many of the marsh birds are already farther along in their seasonal cycle.</p>



<p class="has-black-color has-text-color has-link-color wp-elements-209 wp-block-paragraph">From a dense stand of cattails at the edge of the open water, a sora begins calling again, very close to me. <em>So–ra?, so–ra? </em>fills my ears, this classic voice of Lake Helena’s marsh. Farther away, a Virginia rail, another secretive marsh bird, is giving its <em>gidick, gidick, gidick</em> calls.</p>

<p class="has-black-color has-text-color has-link-color wp-elements-210 wp-block-paragraph">Lake Helena is designated as an Important Bird Area by <a href="https://www.birdlife.org/" target="_blank" rel="noreferrer noopener">BirdLife International</a>: a site specially recognized for its value for bird conservation. Being out here today, that designation is no surprise. As we paddle back past the delta, a light breeze is picking up from the east, pushing up small waves that crash rhythmically against the sandbar. The pelicans are still here, perching alongside four species of gulls and a mixed group of Forster’s terns (<em>Sterna forsteri</em>) and common terns (<em>Sterna hirundo</em>).&nbsp;</p>



<p class="has-black-color has-text-color has-link-color wp-elements-211 wp-block-paragraph">We’ve spent almost six hours out here this morning, and we could happily stay longer. But there’s office work to be done still, and the wind is nudging us that it might be time to leave. But while I sit inside, writing and editing this story, I know that Lake Helena is still there. I know I’ll be back to visit it again, and each time it will remind me how abundant life can be and teach me something new. And I hope that, wherever in the world you are, there’s a special place like this near you, too.</p>

<p class="has-black-color has-text-color wp-block-paragraph">They’re like a flurry of snow in the Montana summer. American white pelicans: massive white birds with chunky orange bills and black wingtips. On the sandbar where Prickly Pear Creek empties into Lake Helena, it’s common to see dozens of them, soaking up the sun more than 30 miles from the nearest nesting colony, on Canyon Ferry Lake. And although visitors to the state are often surprised that Montana, so far from the coast, has pelicans, they’re actually a common sight in the summer.</p>



<p class="has-black-color has-text-color wp-block-paragraph">American white pelicans breed among the prairies, deserts, and forests of the western North American interior, from California and Colorado to Alberta and Manitoba. Across this diverse geographical expanse, they nest in dense colonies, choosing islands within certain marshes or lakes that provide some protection from predators. The nests, often spaced just a few feet apart, can number a thousand or more in a colony.&nbsp;</p>



<h3 class="wp-block-heading">Gregarious living</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="833" src="http://wildwithnature.com/wp-content/uploads/2023/04/234911361-1024x833.jpg" alt="A group of American white pelicans soaring over Helena, Montana." class="wp-image-2318" style="width:512px;height:undefinedpx" srcset="https://wildwithnature.com/wp-content/uploads/2023/04/234911361-1024x833.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/04/234911361-300x244.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/04/234911361-768x625.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/04/234911361.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A group of American white pelicans soaring over Helena, Montana.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">It’s not just nesting, either: almost every aspect of American white pelican life involves groups. They soar in groups, their nine-foot wingspans outstretched as they circle high over mountains and valleys on sun-warmed plumes of air. They fish in groups, commonly traveling 30 miles or more from their nesting colonies to chase carp and other fish in shallow lakes and wetlands. And they migrate in groups, fleeing the cold winters and the bitter winds of the interior prairie to congregate at the edge of the ocean from California and Mexico south to Nicaragua, or around the Gulf of Mexico from Yucatan to Florida.</p>



<p class="has-black-color has-text-color wp-block-paragraph">None of this is out of the ordinary. It’s just the wonderful, striking yearly rhythm of our American white pelicans, these flamboyant fishers of inland marsh and ocean coast. But what <em>is</em> out of the ordinary is to find a pelican &#8211; this social bird of the Montana summer &#8211; somehow surviving an inland winter among the ice.</p>



<h3 class="wp-block-heading">A winter surprise</h3>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">That’s exactly what I saw on March 1, 2023. I was at <a href="http://wildwithnature.com/2022/09/01/spokane-bay/" target="_blank" rel="noreferrer noopener">Spokane Bay</a> near Helena with photographers <a href="https://www.leaf-images.com/" target="_blank" rel="noreferrer noopener">Lea Frye</a> and Rachel Ritacco, looking for wildlife where spring-fed Spokane Creek empties into west-central Montana’s Hauser Lake.</p>



<p class="has-black-color has-text-color wp-block-paragraph">“They don’t all read the books,” said Lea.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">She was referring to the American white pelican in front of us. The week before, a cold front had brought several days of frigid temperatures to Montana, with lows of -13°F. But there was no denying the existence of this bird, with its unmistakable, faded orange bill, here a month before any pelicans should have arrived.</p>



<p class="has-black-color has-text-color wp-block-paragraph">The huge white bird glided smoothly across the small patch of open water at the inlet to the bay. Behind it, a solid barrier of ice spanned the inlet, moaning and grumbling in protest at the gradually-warming March weather.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph"><em>Why was this pelican here now?&nbsp;</em></p>



<p class="has-black-color has-text-color wp-block-paragraph">“Maybe he just has a really good food supply that we don’t know about,” Lea said.</p>



<p class="has-black-color has-text-color wp-block-paragraph">On this relatively mild day, the local, year-round songbirds were heralding the approach of spring. Song sparrows sang cheerfully from the gray and tan cattails in the marsh. Townsend’s solitaires whistled and trilled exuberantly from the junipers on the reddish hills. We could hear the black-capped chickadees whistling their springtime <em>fee-bee</em> song.</p>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">As we approached the area of the bay where the pelican was still swimming, an impressive flock of mallards leapt into the air, a thousand or more of them. Flashing their shimmery green heads and blue wing patches, they retreated to a more distant patch of water. But the pelican remained on the bay, swimming placidly. Was it injured?</p>



<p class="has-black-color has-text-color wp-block-paragraph">We watched as the massive bird unfurled its broad, black-tipped wings and flapped, rising into low flight for about 50 yards before landing again near the mouth of the creek. If the pelican’s flight was impeded by an injury, it wasn’t evident to us.</p>

<p class="has-black-color has-text-color wp-block-paragraph">Researching it later, I learned that the Spokane Bay pelican had been here for much of the winter. Grant Hokit had seen it on December 21, when the air temperature was -17°F. Fed by warm springs welling up from underground, the mouth of Spokane Creek was still open. With a probe, Grant determined that the water temperature six feet down was still a mild 47°F.</p>



<p class="has-black-color has-text-color wp-block-paragraph">“The pelican was perched on a log on the west side of the mouth,” Grant wrote me. “It looked frigid with its head tucked under its wing. I wasn’t sure it was alive and didn’t want to disturb it but it did lift its head at one point. I couldn’t see any sign of injury but it was pretty inactive.”</p>



<h3 class="wp-block-heading">American white pelicans in winter</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="936" src="http://wildwithnature.com/wp-content/uploads/2023/04/DSCN1642-1024x936.jpg" alt="The pelican resting along the shore at Spokane Bay." class="wp-image-2320" style="width:512px;height:undefinedpx" srcset="https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1642-1024x936.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1642-300x274.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1642-768x702.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1642.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">The pelican resting along the shore at Spokane Bay.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">A month later, Garrett Carlson saw the pelican again. It was still there in mid-February, near the open water where Grant had seen it on that frigid day in December. And now, at the beginning of March, the pelican remained. Whether it was starving or thriving was difficult to say &#8211; but it was clear that it had survived the worst of the cold season. In fact, this was the third winter in a row that local birders had found a lone pelican overwintering at Spokane Bay.</p>



<p class="has-black-color has-text-color wp-block-paragraph">As unusual as this seemed at the time, it turns out that the Spokane Bay pelican isn’t the only one to overwinter like this in the frigid North American interior. To be sure, the vast majority of the estimated 450,000 American white pelicans on the continent migrate to warmer climates for the winter. But the Spokane Bay observations are not entirely isolated. In Montana, the occasional (mostly solitary) pelican has been seen off and on over recent winters at a handful of locations, including the Missouri River below Fort Peck Reservoir and Hauser Dam as well as Giant Springs State Park in Great Falls.</p>



<h3 class="wp-block-heading">Winter fishing</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="791" src="http://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-1024x791.jpg" alt="The pelican swimming in the open water at Spokane Bay." class="wp-image-2321" style="width:512px;height:undefinedpx" srcset="https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-1024x791.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-300x232.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-768x593.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-1536x1187.jpg 1536w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-2048x1582.jpg 2048w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">The pelican swimming in the open water at Spokane Bay.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">What do these sites all have in common? They’re water bodies associated with springs, outflow from a dam, or some other condition that maintains open water through bitterly cold weather. If a fish-eating pelican is going to survive a mid-continent winter, this is clearly the sort of place it wants to be.</p>



<p class="has-black-color has-text-color wp-block-paragraph">I talked with Scot Bealer, an avid angler who has worked as a fishing guide and a biologist, to learn more about how warm spots like these might affect winter fishing opportunities for pelicans.</p>



<p class="has-black-color has-text-color wp-block-paragraph">“Springs are a thermal attractant to fish,” he told me.&nbsp;</p>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">Patches of unseasonably warm water may support additional aquatic insects, drawing in trout, carp, and other species.</p>



<p class="has-black-color has-text-color wp-block-paragraph">“In Colorado, I have seen fish absolutely stack up in places like that,” Scot continued.</p>



<p class="has-black-color has-text-color wp-block-paragraph">And it’s not just in Montana that pelicans will sometimes overwinter in places like these. Shortly after I saw the early-March pelican at Spokane Bay, Alberta birder and photographer John Reasbeck got in touch with me. He told me that at southern Alberta’s Frank Lake, 280 miles northwest of Spokane Bay, an American white pelican with an injured right wing had stayed through much of the winter. In this case, a pipe that discharged treated wastewater into the lake was the source of the warmer-than-usual water. (Find more of that story <a href="https://byrdpyx.com/blogs" target="_blank" rel="noreferrer noopener">on his blog</a>.) In fact, it was the third winter in a row that a pelican with a wing injury &#8211; which John suspected was the same individual &#8211; had overwintered there.</p>



<h3 class="wp-block-heading">Goodbye, Elsa</h3>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">John named the pelican Elsa and visited her frequently through the winter. He watched her swimming, preening, and catching fish below the wastewater pipe. In January, in spite of her injury, Elsa began flying, exercising her massive wings as she flapped over the icy lake. Finally, on January 31, she flew away.</p>



<p class="has-black-color has-text-color wp-block-paragraph">“She flew right by me at Frank Lake,” John wrote me. “Then she banked to the left and I never saw her again. I’ve been saying ‘her,’ but we don’t really know for sure. We do know that she is on the small side as compared with other pelicans. Males are usually larger. So, we’re guessing female. Besides, with Elsa having survived so many days with -30°C [-22°F] temperatures, it just seemed fitting to give her the name of the princess from <em>Frozen</em>.”</p>



<h3 class="wp-block-heading">Surviving the cold</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="964" src="http://wildwithnature.com/wp-content/uploads/2023/04/DSCN1622-1024x964.jpg" alt="The pelican standing in shallow water at Spokane Bay." class="wp-image-2322" style="width:512px;height:undefinedpx" srcset="https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1622-1024x964.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1622-300x283.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1622-768x723.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1622.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">The pelican standing in shallow water at Spokane Bay.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">What is going on with these overwintering white pelicans? Several of the Montana birds, like Elsa in Alberta, have had wing injuries. A pelican that spent the winter of 2012-2013 at Giant Springs State Park, for example, had an injured left wing. Great Falls birder Beth Hill wrote me that she never saw this bird catch fish successfully. It seemed to get thinner and thinner and eventually disappeared, in the spring as the migrating pelicans were starting to return. Beth suspects this bird died. But there have also been others, such as this winter’s Spokane Bay bird, that seem to be capable fliers with no evidence of an injury.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Are all of these unusual, inland overwinterers just surviving, making the most of a brutal winter in the few patches of relatively warm water that might just allow them to make it? Are they pushing the limits of starvation, just barely getting to spring alive? Or are some of them thriving, maintaining good condition and saving themselves the effort of migrating?</p>



<p class="has-black-color has-text-color wp-block-paragraph">Without actually capturing these overwintering birds and checking their condition, it’s hard to know for sure. But when I asked Allison Begley, Avian Conservation Biologist with Montana Fish, Wildlife, and Parks, for her thoughts on the pelican question, she had some intriguing suggestions. Allison pointed me towards <a href="https://www.researchgate.net/publication/327942314_Changes_in_abundance_productivity_and_distribution_of_western_American_White_Pelicans_Pelecanus_erythrorhynchos_1981-2014" target="_blank" rel="noreferrer noopener">the work of Colleen Moulton and her collaborators</a>. These Idaho biologists took a careful look at decades of observations of pelican breeding populations across western North America &#8211; and they found some interesting trends.</p>



<h3 class="wp-block-heading">Shifting northward?</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="905" src="http://wildwithnature.com/wp-content/uploads/2023/04/234803131-1024x905.jpg" alt="An American white pelican flies over Lake Helena in May." class="wp-image-2370" style="width:512px;height:undefinedpx" srcset="https://wildwithnature.com/wp-content/uploads/2023/04/234803131-1024x905.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/04/234803131-300x265.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/04/234803131-768x679.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/04/234803131.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">An American white pelican flies over Lake Helena in May.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">From California to Montana, it turns out, the western population of American white pelicans has been shifting its breeding range northward since the 1970s. In part, it&#8217;s been a response to water shortages at previously-used breeding sites in California. The range shift also reflects the formation of new breeding colonies farther north, perhaps in response to the warming climate. Could the handful of pelicans overwintering in the north be related, a response to milder winters? </p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;I certainly think it&#8217;s interesting to speculate,&#8221; Allison told me. </p>



<p class="has-black-color has-text-color wp-block-paragraph">Now, with the arrival of spring, the pelicans are returning. Moving northward from Mexico in groups, some of them ride thermals <a href="https://wildlife.utah.gov/news/wildlife-blog/428-the-paths-of-pelicans.html" target="_blank" rel="noreferrer noopener">to an unbelievable 33,000 feet</a>, where the air is frigid and airliners cruise by. Already they&#8217;re starting to show up again at the recently-thawed wetlands of the interior, hunting suckers and carp. Soon they&#8217;ll be raising another generation of young. </p>



<p class="has-black-color has-text-color wp-block-paragraph">As the weather turns cold again this fall, will all of them leave? Will the intrepid handful of pelicans that spend the winter at Spokane Bay, Frank Lake, and other unfrozen sites increase over time? Keep your eyes open for winter pelicans &#8211; and let me know what you see. And in the years ahead, hopefully some more answers will emerge.</p>

<p class="has-black-color has-text-color wp-block-paragraph">Son como una ráfaga de nieve en el verano de Montana, EE.UU. Pelícanos blancos americanos: son masivas aves blancas con gruesos picos anaranjados y puntas negras en las alas. En el banco de arena donde el Arroyo Prickly Pear desemboca en el Lago Helena, es común ver docenas de ellos, absorbiendo el calor del sol. Están más de 30 millas lejos de la colonia de anidación más cerca, en el Lago Canyon Ferry. Y aunque visitantes al estado se sorprenden a ver que Montana, tan lejos de la costa, tenga pelícanos, realmente son comunes acá en el verano. </p>



<p class="has-black-color has-text-color wp-block-paragraph">Los pelícanos blancos americanos (<em>Pelecanus erythrorhynchos</em>) pasan la estación reproductiva entre las praderas, los desiertos, y los bosques del interior oeste de Norteamérica, desde California y Colorado hasta Alberta y Manitoba. En varios lugares dentro de esta gran extensión geográfica, anidan en colonias densas. Escogen islas dentro de ciertos humedales o lagos que provean algún nivel de protección de los depredadores. Los nidos, a menudo separados por sólo unos pies, pueden ascender a mil o más en una colonia.</p>

<p class="has-black-color has-text-color wp-block-paragraph">No es sólo anidar: casi cada aspecto de la vida de los pelícanos blancos americanos envuelva grupos. Vuelan en grupos, sus envergaduras de nueve pies desplegadas mientras circunvuelan alto sobre las montañas y los valles sobre columnas de aire calentado por el sol. Pescan en grupos. A menudo viajan 30 millas o más desde las colonias para perseguir carpas y otros peces en lagos y humedales. Y migran en grupos, huyendo los inviernos fríos y los vientos amargos de la pradera interior. Se congregan entonces al borde del océano, desde California y México hasta Nicaragua o en el Golfo de México desde Yucatán hasta Florida.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Nada de esto es insólito. Sólo es el maravilloso ritmo anual de nuestros pelícanos blancos americanos, estos pescadores ostentosos del humedal interior y la costa marina. Pero lo que sí <em>es</em> insólito es encontrar un pelícano &#8211; esta ave gregaria del verano de Montana &#8211; sobreviviendo un invierno interior, de alguna manera, entre el hielo.</p>

<p class="has-black-color has-text-color wp-block-paragraph">Eso es exactamente lo que vi el 1 de marzo de 2023. Estaba cerca de <a href="http://wildwithnature.com/2022/09/01/spokane-bay/" target="_blank" rel="noreferrer noopener">la Bahía de Spokane</a> con las fotógrafas <a href="https://www.leaf-images.com/" target="_blank" rel="noreferrer noopener">Lea Frye</a> y Rachel Ritacco, buscando la vida silvestre. El Arroyo Spokane, alimentado por un manantial, desemboca acá en el Lago Hauser, en la parte central del oeste de Montana.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Es que no todos ellos leen los libros,&#8221; dijo Lea.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">Refería al pelícano blanco americano frente a nosotros. La semana antes, una frente de frío había traído varios días de temperaturas frígidas a Montana, con mínimos de -13°F. Pero no pudimos negar la existencia de esta ave, con su inconfundible pico de anaranjado borroso. Estaba acá un mes antes de que ningunos pelícanos debían haber llegado. </p>



<p class="has-black-color has-text-color wp-block-paragraph">La enorme ave blanca se deslizaba suavemente por el parche pequeño de agua no congelada en la entrada a la bahía. Detrás de ella, una barrera sólida de hielo cubría la bahía. El hielo gemía y se quejaba en protesta al clima gradualmente calentando de marzo.</p>



<p class="has-black-color has-text-color wp-block-paragraph"><em>¿Por qué el pelícano estaba acá ahora?&nbsp;</em></p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Tal vez tenga una buena provisión de comida de la que no sabemos,&#8221; dijo Lea. </p>



<p class="has-black-color has-text-color wp-block-paragraph">En este día relativamente templado, las locales aves cantoras que suelen quedarse todo el año anunciaban el acercamiento de la primavera. Gorriones cantores (<em>Melospiza melodia</em>) cantaban alegremente desde las totoras grises y bronceadas del humedal. Clarines norteños (<em>Myadestes townsendi</em>) silbaban y trinaban con exuberancia de los juníperos en las colinas rojizas. Podíamos oír los carboneros cabecinegros (<em>Poecile atricapillus</em>) silbando su canto primaveral, <em>fee-bee</em>.</p>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">Cuando nos acercamos al área de la bahía donde el pelícano seguía remando, una bandada impresionante de patos de collar (<em>Anas platyrhynchos</em>) saltó en el aire, un mil o más de ellos. Destellando las relucientes cabezas verdes y las manchas azules en las alas, se retiraron a un parche más grande de agua no congelada en la distancia. Pero el pelícano se quedó sobre la bahía, remando tranquilo. ¿Estaba herido?</p>



<p class="has-black-color has-text-color wp-block-paragraph">Miramos mientras el ave masiva desplegó sus amplias alas con la puntas negras y batió, elevándose para volar a baja altura por 50 yardas antes de aterrizar otra vez cerca de la desembocadura del arroyo. Si alguna herida impedía el vuelo del pelícano, no lo pudimos ver.</p>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">Después, investigándolo más, aprendí que el pelícano de la Bahía de Spokane había estado acá por gran parte del invierno. Grant Hokit lo había visto el 21 de diciembre, cuando la temperatura del aire era de -17°F. Alimentado por los manantiales tibios surgiendo de la tierra, la desembocadura del Arroyo Spokane se mantenía no congelada. Con una sonda, Grant determinó que la temperatura del agua seis pies bajo la superficie era de unos agradables 47°F.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;El pelícano se posaba en un tronco caído al lado oeste de la desembocadura,&#8221; Grant me escribió. &#8220;Parecía frígido, con la cabeza metida bajo la ala. Yo no estaba seguro que aún estuviera vivo y no quería molestarlo, pero en algún momento levantó la cabeza. No pude ver ninguna señal de una herida, pero quedaba bastante inactivo.&#8221;</p>



<h3 class="wp-block-heading">Los pelícanos blancos americanos en el invierno</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="936" src="http://wildwithnature.com/wp-content/uploads/2023/04/DSCN1642-1024x936.jpg" alt="The pelican resting along the shore at Spokane Bay." class="wp-image-2320" style="width:512px;height:undefinedpx" srcset="https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1642-1024x936.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1642-300x274.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1642-768x702.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1642.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">El pelícano descansando en la orilla de la Bahía de Spokane.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Un mes después, Garrett Carlson lo vio al pelícano otra vez. Todavía estaba ahí en medio febrero, cerca del agua no congelada donde Grant lo había visto durante el día frígido de diciembre. Y ahora, al comienzo de marzo, el pelícano aún se quedaba. Si estaba prosperando o muriendo de hambre era difícil saber &#8211; pero estaba claro que había sobrevivido lo peor de la estación fría. De hecho, esto fue el tercero invierno consecutivo en el que pajareros locales habían encontrado un solo pelícano pasando el invierno en la Bahía de Spokane.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Tan inusual que parecía en el momento, resulta que el pelícano de la Bahía de Spokane no es el único que ha pasado el invierno así en el interior frígido de Norteamérica. Ciertamente, la gran mayoría de los 450.000 pelícanos blancos americanos que se estima que hay en el continente migran a lugares más calurosos durante el invierno. Pero las observaciones en la Bahía de Spokane no son completamente aisladas. En Montana, un pelícano ocasional (y generalmente solitario) ha sido visto de vez en cuando en inviernos recientes en unos lugares, incluso el Río Missouri bajo el Embalse Fort Peck y <a href="http://wildwithnature.com/2023/02/03/muerte-por-aguila/" target="_blank" rel="noreferrer noopener">la Presa de Hauser</a> y también el Parque de los Manantiales Gigantes en Great Falls. </p>



<h3 class="wp-block-heading">Pescando en el invierno</h3>

<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="791" src="http://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-1024x791.jpg" alt="The pelican swimming in the open water at Spokane Bay." class="wp-image-2321" style="width:512px;height:undefinedpx" srcset="https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-1024x791.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-300x232.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-768x593.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-1536x1187.jpg 1536w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1636-2048x1582.jpg 2048w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">El pelícano en la Bahía de Spokane.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">¿Qué tienen todos estos lugares en común? Son masas de aguas asociadas con manantiales, el desagüe de una presa u otra condición que mantenga el agua no congelada a través de los tiempos de intenso frío. Si un pelícano, dependiendo de los peces, fuera a sobrevivir un invierno en el interior del continente, esto es claramente el tipo de lugar en el que querría estar. </p>



<p class="has-black-color has-text-color wp-block-paragraph">Hablé con Scot Bealer, un pescador ávido que ha trabajado como guía de pesca y biólogo, para aprender más. ¿Cómo podrían afectar lugares templados como estos a los pelícanos respecto a las oportunidades invernales para pescar?</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Los manantiales son un atractivo térmico para peces,&#8221; me dijo.</p>


<div class="wp-block-image">

</div>


<p class="has-black-color has-text-color wp-block-paragraph">Parches de agua extemporáneamente cálidos podrían mantener a una abundancia de insectos acuáticos, atrayendo a truchas, carpas y otras especies de peces.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;En Colorado, he visto peces congregándose muchísimo en lugares así,&#8221; Scot aseguró. </p>



<p class="has-black-color has-text-color wp-block-paragraph">Y no es sólo en Montana que los pelícanos a veces pasen el invierno en lugares así. Pronto después de que vi el pelícano en la Bahía de Spokane, el pajarero y fotógrafo John Reasbeck me contactó. Me dijo que había estado un pelícano con la ala derecha herida que se quedó por mucho del invierno en el Lago Frank del sur de Alberta, Canadá, 280 millas al noroeste de la Bahía de Spokane. En este caso, una cañería que descargaba tratadas aguas residuales en el lago era la fuente del agua más cálida que lo usual. (Lee más de aquella historia <a href="https://byrdpyx.com/blogs" target="_blank" rel="noreferrer noopener">en su blog</a>.) De hecho, fue el tercero invierno consecutivo en el que un pelícano con la ala herida &#8211; John sospechaba que era el mismo individuo &#8211; había pasado el invierno allá. </p>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">John llamó el pelícano Elsa y la visitó frecuentemente a través del invierno. La vio nadando, acicalándose y atrapando peces aguas abajo de la cañería de aguas residuales. En enero, a pesar de su lesión, Elsa empezó a volar, ejerciendo sus alas masivas mientras batía sobre el lago helado. Finalmente, el 31 de enero, se fue volando. </p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Ella voló por mí sobre el Lago Frank,&#8221; John me escribió. &#8220;Entonces se inclinó a la izquierda y nunca jamás la vi. He estado diciendo ‘ella,’ pero realmente no sabemos de veras. Lo que sí sabemos es que ella es más pequeña en comparación con otros pelícanos. Los machos suelen ser más grandes. Por eso, estamos adivinando que sea una hembra. Además, dado que Elsa sobrevivió tantos días con temperaturas de -30°C [-22°F], pareció apto darle el nombre de la princesa de la película <em>Frozen</em>.&#8221;</p>



<h3 class="wp-block-heading">Sobreviviendo el frío</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="964" src="http://wildwithnature.com/wp-content/uploads/2023/04/DSCN1622-1024x964.jpg" alt="The pelican standing in shallow water at Spokane Bay." class="wp-image-2322" style="width:512px;height:undefinedpx" srcset="https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1622-1024x964.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1622-300x283.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1622-768x723.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/04/DSCN1622.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">El pelícano en el agua poco profunda en la Bahía de Spokane.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">¿Qué pasa con estos pelícanos que pasan el invierno en el frío? Algunos de los individuos en Montana, como Elsa en Alberta, tuvieron alas heridas. Un pelícano que sobrevivió el invierno de 2012-2013 en el Parque de los Manantiales Gigantes, por ejemplo, tenía la ala izquierda herida. La pajarera Beth Hill, de Great Falls, me escribió que nunca vio esta ave pescar con éxito. Pareció volverse más y más flaca y finalmente desapareció, en la primavera cuando los pelícanos migratorios empezaban a volver. Beth sospecha que esta ave murió. Pero han habido otros, como el pelícano de este invierno en la Bahía de Spokane, los cuales parecen ser muy capaces de volar, sin ninguna evidencia de una lesión. </p>



<p class="has-black-color has-text-color wp-block-paragraph">¿Estos individuos inusuales sólo están sobreviviendo, tratando de aguantar el clima brutal en los escasos parches de agua relativamente tibia que quizá les dejaran salir bien? Están tocando los límites de la hambre, apenas llegando vivos a la primavera? O ¿algunos están prosperando, manteniendo buena condición y evitando la dificultad de migrar?</p>



<p class="has-black-color has-text-color wp-block-paragraph">Sin capturar estas aves por el invierno y revisar su condición, es imposible saber de veras. Pero cuando le pregunté a Allison Begley, una Bióloga de la Conservación de las Aves con Montana Fish, Wildlife and Parks, tuvo unas sugerencias intrigantes. Allison me dirigió a <a href="https://www.researchgate.net/publication/327942314_Changes_in_abundance_productivity_and_distribution_of_western_American_White_Pelicans_Pelecanus_erythrorhynchos_1981-2014" target="_blank" rel="noreferrer noopener">los estudios de Colleen Moulton y sus colegas</a>. Estos biólogos en Idaho examinaron atentamente las observaciones a través de décadas de las poblaciones reproductivas de pelícanos en la parte oeste de Norteamérica &#8211; y encontraron algunas tendencias interesantes.</p>



<h3 class="wp-block-heading">¿Moviéndose hacia el norte?</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="905" src="http://wildwithnature.com/wp-content/uploads/2023/04/234803131-1024x905.jpg" alt="An American white pelican flies over Lake Helena in May." class="wp-image-2370" style="width:512px;height:undefinedpx" srcset="https://wildwithnature.com/wp-content/uploads/2023/04/234803131-1024x905.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/04/234803131-300x265.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/04/234803131-768x679.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/04/234803131.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Un pelícano blanco americano sobrevuela el Lago Helena en mayo.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Resulta que, desde California hasta Montana, la población occidental de pelícanos blancos americanos ha estado cambiando su extensión reproductiva hacia el norte desde los años 1970. En parte, es una respuesta a la escasez de agua en colonias previamente usadas en California. El cambio en extensión también refleja la formación de adicionales colonias reproductivas más al norte, tal vez en reacción al clima volviéndose más cálido. ¿Podría ser que el manojo de pelícanos que pasan el invierno en el norte también sea relacionado, una reacción a los inviernos más tibios?</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Pienso que definitivamente es interesante especular,&#8221; Allison me dijo.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Con la llegada de la primavera, los pelícanos ya están regresando. Moviendo en grupos de México para el norte, algunos de ellos dan vueltas sobre las térmicas <a href="https://wildlife.utah.gov/news/wildlife-blog/428-the-paths-of-pelicans.html" target="_blank" rel="noreferrer noopener">hasta una altura increíble de 33.000 pies</a>, donde el aire se mantiene frígido y los aviones comerciales vuelan. Algunos ya empiezan a aparecer en los humedales recientemente descongelados del interior, cazando matalotes y carpas. Pronto van a estar criando a otra generación de pelícanos jóvenes. </p>



<p class="has-black-color has-text-color wp-block-paragraph">Cuando el clima se vuelva frío otra vez este otoño, ¿todos los pelícanos van a irse? ¿Aumentará con el tiempo el manojo intrépido que pasan el invierno en la Bahía de Spokane, el Lago Frank y otros sitios no congelados? Mantén los ojos abiertos para pelícanos invernales &#8211; y déjame saber lo que veas. Y en los años que vienen, espero que algunas respuestas vayan a emerger.</p>

<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2022/09/DSCN0546-1024x768.jpg" alt="Mallards at the algae-covered mouth of Spokane Creek." class="wp-image-1074" style="width:512px;height:384px" srcset="https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0546-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0546-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0546-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0546.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Mallards swimming at the algae-covered mouth of Spokane Creek.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">The sun is hot on this midday at the end of summer, but the breeze carries a cool hint of fall. A delta of bright green algae marks the mouth of Spokane Creek where it flows lazily into the bay on Hauser Lake. Twenty mallards are swimming slowly away from me, following the shallow blue channels that wind among the algae. A lone female hooded merganser is swimming alongside them. Otherwise, the bay is empty of waterfowl.</p>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="873" src="http://wildwithnature.com/wp-content/uploads/2022/09/DSCN0536-1024x873.jpg" alt="American white pelicans swimming at the edge of Spokane Bay among the reflections of the reddish late-summer leaves of the golden currant (Ribes aureum)." class="wp-image-1075" style="width:512px;height:437px" srcset="https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0536-1024x873.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0536-300x256.jpg 300w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0536-768x655.jpg 768w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0536.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">American white pelicans swimming at the edge of Spokane Bay among the reflections of the reddish late-summer leaves of the golden currant (Ribes aureum).</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Earlier, I had watched two pelicans swimming placidly along the far shore, where the steep hills of pink-orange shale rise up. Three sandhill cranes were circling over the bay, their throbbing calls echoing off of the slope. </p>



<p class="has-black-color has-text-color wp-block-paragraph">The cranes have landed now. They’re foraging quietly among the rushes and cattails near the mouth of the creek, picking methodically among the damp vegetation.</p>



<h3 class="wp-block-heading">Early migrants</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="888" src="http://wildwithnature.com/wp-content/uploads/2022/09/DSCN0568-1024x888.jpg" alt="A drab fall yellow-rumped warbler foraging in a cottonwood." class="wp-image-1078" style="width:512px;height:444px" srcset="https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0568-1024x888.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0568-300x260.jpg 300w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0568-768x666.jpg 768w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0568.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A drab fall yellow-rumped warbler foraging in a cottonwood.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Fall migration is already underway. The shorebirds were some of the earliest to migrate &#8211; <a href="https://ebird.org/region/US-MT-049/media?yr=all&amp;m=#semplo" target="_blank" rel="noreferrer noopener">since the end of July</a>, they’ve been passing through the Helena Valley. But now, the songbirds are beginning to move, too. Here at Spokane Bay this morning, the native cottonwoods (<em>Populus</em> sp.) and the non-native crack willows (<em>Salix fragilis</em>) along the water are full of yellow-rumped warblers. Yellow-rumps are breeding birds of the conifer forest. Seeing them here, in riparian habitat along the lake, it’s clear that they’re already migrating. Their <em>spic</em> calls fill the trees as they flit from leaf to leaf, hunting insects.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Occasionally I also hear the sharper <em>chip</em> calls of a Wilson’s warbler. These furtive birds nest along mountain streams and beaver ponds. Now they’re beginning to migrate, too. They’re much less common than the yellow-rumps today, though. This morning I’ve counted just five of them, scattered in the trees and shrubs around the bay. At the same time, I’ve counted 40 yellow-rumps.</p>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="945" src="http://wildwithnature.com/wp-content/uploads/2022/09/DSCN0573-1024x945.jpg" alt="A yellow warbler foraging in a cottonwood." class="wp-image-1079" style="width:512px;height:473px" srcset="https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0573-1024x945.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0573-300x277.jpg 300w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0573-768x708.jpg 768w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0573.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A yellow warbler foraging in a cottonwood.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">We’re still near the start of this fast-moving season of transition. Here at Spokane Bay, many of our summer breeding birds are sticking around. Spotted towhees mew from the dry, shrubby slopes. A western wood-pewee sings his lazy, descending slur from the crack willows. Several gray catbirds mew from dense shrubs near the stream. A few of the yellow warblers that probably nested here this summer are still around, hunting insects in the cottonwoods.</p>



<h3 class="wp-block-heading">Into the hills</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="828" src="http://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_183922542-1024x828.jpg" alt="Broom snakeweed (Gutierrezia sarothrae) blooming in the grassland." class="wp-image-1081" style="width:512px;height:414px" srcset="https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_183922542-1024x828.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_183922542-300x243.jpg 300w, https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_183922542-768x621.jpg 768w, https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_183922542.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Broom snakeweed (Gutierrezia sarothrae) blooming in the grassland.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">In the grassland on the hills, the clattering crepitations of grasshoppers, red-winged and yellow-winged, fill the air. The broom snakeweed (<em>Gutierrezia sarothrae</em>) is in full bloom now. The dotted blazing star (<em>Liatris punctata</em>) is almost done flowering, while rubber rabbitbrush (<em>Ericameria nauseosa</em>) is just beginning.</p>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="888" src="http://wildwithnature.com/wp-content/uploads/2022/09/DSCN0556-1024x888.jpg" alt="A pinyon jay - one of five in this flock - perching in a Rocky Mountain juniper (Juniperus scopulorum)." class="wp-image-1080" style="width:512px;height:444px" srcset="https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0556-1024x888.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0556-300x260.jpg 300w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0556-768x666.jpg 768w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0556.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A pinyon jay &#8211; one of five in this flock &#8211; perching in a Rocky Mountain juniper (Juniperus scopulorum).</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">By now I’ve climbed nearly to the ridgeline, hiking through the bright yellow clumps of broom snakeweed and the tufts of the bunchgrasses. Suddenly, in the distance, I hear a chorus of strange calls. They remind me vaguely of Clark’s nutcrackers, but each call is like a question mark. It slurs strongly upwards and then drops off again.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">Then I see them, sailing over the bay in an undulating line, heading for a Rocky Mountain juniper (<em>Juniperus scopulorum</em>) below me. They’re pinyon jays, dusty blue from their beaks to their tail feathers. They land in the juniper, making more of their questioning calls, then continue to a more-distant ponderosa pine. I manage to get a bad recording of them calling in the distance, a nasal <em>wee-ow</em> above the constant conversation of the wind and the grasses.</p>



<h3 class="wp-block-heading">Pinyon jay biology</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="804" src="http://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_184622097-1024x804.jpg" alt="The dry, hilly shale habitat where I saw the pinyon jays." class="wp-image-1084" style="width:512px;height:402px" srcset="https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_184622097-1024x804.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_184622097-300x236.jpg 300w, https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_184622097-768x603.jpg 768w, https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_184622097.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">The dry, hilly habitat where I saw the pinyon jays.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">I’ve been watching for pinyon jays since I first arrived in Helena six years ago. And over those years of casual looking, they’ve always eluded me. Around Helena, the Scratchgravel Hills and the nearby Forestvale Cemetery are the places where birders see them most frequently. But even there, a pinyon jay sighting is never a sure thing. And in the Spokane Bay area, across the Helena Valley from the Scratchgravel Hills, it’s been 22 years since anyone has reported pinyon jays.</p>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="768" src="http://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_162452005-1024x768.jpg" alt="Spokane Bay, bordered by shaly grassland with scattered junipers." class="wp-image-1086" style="width:512px;height:384px" srcset="https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_162452005-1024x768.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_162452005-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_162452005-768x576.jpg 768w, https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_162452005-1536x1152.jpg 1536w, https://wildwithnature.com/wp-content/uploads/2022/09/PXL_20220830_162452005.jpg 1800w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Spokane Bay, bordered by shaly grassland with scattered junipers.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Pinyon jays are birds of the interior west. They’re usually associated with pinyon pines, whose seeds they harvest and cache for food. But interestingly, although we don’t have pinyon pines in Montana, we do have pinyon jays. According to the excellent reference <a href="https://www.buteobooks.com/product/BBMT.html" target="_blank" rel="noreferrer noopener"><em>Birds of Montana</em></a>, these birds are residents in much of the state east of the continental divide, where they’re associated with ponderosa pine and limber pine-juniper forests.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">Without pinyon pines in Montana, what do pinyon jays eat? <em>Birds of Montana</em> suggests that our local pinyon jays probably eat pine seeds, too &#8211; just not pinyon pines. But pine seeds aren’t the entire diet. <em>Birds of Montana </em>also relays some observations made over a century ago in far-eastern Montana, near Fallon. There, ornithologist Ewen Cameron saw pinyon jays flipping over cow pies to hunt beetles. During the winter, he watched them feeding on juniper berries.</p>



<h3 class="wp-block-heading">Why I write</h3>


<div class="wp-block-image">
<figure class="alignright size-large is-resized"><img loading="lazy" decoding="async" width="1024" height="837" src="http://wildwithnature.com/wp-content/uploads/2022/09/DSCN0565-1024x837.jpg" alt="A sandhill crane foraging in the marsh." class="wp-image-1085" style="width:512px;height:419px" srcset="https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0565-1024x837.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0565-300x245.jpg 300w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0565-768x628.jpg 768w, https://wildwithnature.com/wp-content/uploads/2022/09/DSCN0565.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A sandhill crane foraging in the marsh.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">From the completely unexpected pinyon jays to the first migrating warblers, it’s been a good day for birds. Today, Spokane Bay has reminded me, once again, why I write. I write because I love being out here. The stories are different every day, and I want to share them with you. Today it’s the cranes bugling over the marsh, the mallards and a hooded merganser swimming at the mouth of the creek. It’s the warblers feeding in the willows, the broom snakeweed covering the hillsides with gold, and the possibility of pinyon jays landing, unexpected, in a juniper.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">Being out here gives me a sense of wonder and lets me feel grounded in the place where I live. When I’m here, I’m connected to the changing of the seasons through my eyes, my ears, and my bones. And no matter how much I may be doubting &#8211; questioning my purpose, despairing at all that seems wrong in the world &#8211; somehow, after sitting out here, a measure of hope and awe always comes seeping back in. I hope that these stories do the same for you.</p>
