</div>


<p class="has-black-color has-text-color wp-block-paragraph">When I left snow-covered Montana a few days ago to visit friends in Seattle, Washington, it was a sudden transition from the depths of late winter into full-fledged spring. Today, the morning sun is making the feathery branches of the western redcedars glow a soft green. It illuminates a dark-eyed junco, trilling exuberantly from the willow at the edge of the lake. All around Seattle, the dandelions are emerging like brilliant spots of sunshine among the grasses.&nbsp;</p>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img decoding="async" width="1024" height="713" src="http://wildwithnature.com/wp-content/uploads/2023/03/DSCN1735-1024x713.jpg" alt="An American wigeon grazing on the lawn at Green Lake Park." class="wp-image-2226" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1735-1024x713.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1735-300x209.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1735-768x535.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1735.jpg 1200w" sizes="(max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">An American wigeon grazing on the lawn.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">In the middle of this bustling city, <a href="https://www.seattle.gov/parks/allparks/green-lake-park" target="_blank" rel="noreferrer noopener">Green Lake Park</a> is an oasis of water and plants, humming with humans and birds. People walk, jog, and push strollers along the paved trail that circles around this urban lake. American wigeons and Canada geese graze on the lawns. Song sparrows sing from the cattails and the Himalayan blackberries along the water, and golden-crowned kinglets flit along the Douglas-fir branches, gleaning tiny invertebrates.</p>



<p class="has-black-color has-text-color wp-block-paragraph">A few days ago, the ruby-crowned kinglets started their springtime singing here. Now we can hear them all around the park, the lispy introductory notes of their song transforming suddenly into an exuberant, chattering crescendo.&nbsp;</p>



<h3 class="wp-block-heading">Connecting with the birds</h3>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="987" src="http://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_170525615.MP_-1-1024x987.jpg" alt="Roniq Bartanen discusses scaup identification at Green Lake Park." class="wp-image-2229" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_170525615.MP_-1-1024x987.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_170525615.MP_-1-300x289.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_170525615.MP_-1-768x740.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_170525615.MP_-1.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Roniq Bartanen discusses identification of scaup (a group of ducks) at Green Lake Park.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">“It’s been spring for the birds for a while,” says Roniq Bartanen.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">Roniq, a professional bird guide (<a href="https://shebirds.com/" target="_blank" rel="noreferrer noopener">find out more about her work here</a>), has been watching the birds at Green Lake for years. Today, I’m one of over 20 people who have joined her for the free monthly bird walk she leads here. It’s one of a number of these regular, urban bird walks, coordinated by <a href="https://seattleaudubon.org/" target="_blank" rel="noreferrer noopener">Birds Connect Seattle</a>. This organization &#8211; which envisions “cities where birds and people thrive” &#8211; <a href="https://seattleaudubon.org/2023/03/28/a-new-name-for-an-inclusive-future/" target="_blank" rel="noreferrer noopener">recently changed its name</a> from Seattle Audubon. The new name emphasizes all of the ways that birds connect us to each other, the landscape around us, and the larger world.&nbsp;</p>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="933" src="http://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_182942022-1024x933.jpg" alt="Red-flowering currant (Ribes sanguineum)." class="wp-image-2228" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_182942022-1024x933.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_182942022-300x273.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_182942022-768x700.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_182942022.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Red-flowering currant (<em>Ribes sanguineum</em>).</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">At Green Lake Park, the plants, too, are telling us of connection with the birds. The red-flowering currant (<em>Ribes sanguineum</em>) is in full bloom, its clusters of rich pink flowers contrasting with the unfolding, deeply textured leaves. Roniq says that, in this coastal ecosystem, it’s one of the earliest native plants to flower. In her yard, it’s been blooming for nearly a month already. The Anna’s hummingbirds, which remain around Seattle throughout the winter, often visit these striking pink blooms. Before long, the highly-migratory rufous hummingbirds will join them here as these long-distance travelers return from their winter homes in Mexico.</p>



<h3 class="wp-block-heading">More signs of spring</h3>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="864" src="http://wildwithnature.com/wp-content/uploads/2023/03/DSCN1750-1024x864.jpg" alt="A great blue heron, with its breeding-season feather plumes, at Green Lake Park." class="wp-image-2231" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1750-1024x864.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1750-300x253.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1750-768x648.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1750.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A great blue heron, with its breeding-season feather plumes, at Green Lake Park.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Over the course of our bird walk, signs of spring are all around us. And it’s not just the blooms of the dandelions and red-flowering currants. A pair of bushtits are starting to build their sock-like, hanging nest in a western redcedar. A great blue heron standing in the shallows is sporting its long, breeding-season feather plumes. At one point, I see a black-capped chickadee disappearing into the decaying end of a broken birch branch, where it presumably has its nest.</p>



<p class="has-black-color has-text-color wp-block-paragraph">“This is the time of year when the hormones are going, so the birds are moving fast… they’re chasing each other, they’re building nests,” Roniq says.</p>



<p class="has-black-color has-text-color wp-block-paragraph">It’s an exciting time to be walking here, sharing the wonder of the season.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Easily distracted by conversation and by so many birds, I find myself lagging behind most of the group. I’m with a few other birders, walking slowly, when we see an Anna’s hummingbird doing something that surprises me. She’s hovering near a sprawling tangle of Himalayan blackberries along the water’s edge. As we watch, she moves methodically from one blackberry leaf to the next, probing the edges of the undersides with her slender beak.&nbsp;</p>



<h3 class="wp-block-heading">The Anna&#8217;s hummingbird mystery</h3>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1007" height="1024" src="http://wildwithnature.com/wp-content/uploads/2023/03/DSCN1732_crop-1007x1024.jpg" alt="The Anna's hummingbird probing Himalayan blackberry leaves." class="wp-image-2232" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1732_crop-1007x1024.jpg 1007w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1732_crop-295x300.jpg 295w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1732_crop-768x781.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1732_crop.jpg 1200w" sizes="auto, (max-width: 1007px) 100vw, 1007px" /><figcaption class="wp-element-caption">The Anna&#8217;s hummingbird probing Himalayan blackberry leaves.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Hummingbirds are well-known for feeding on flower nectar… but the blackberries are nowhere near flowering yet. What is she doing?</p>



<p class="has-black-color has-text-color wp-block-paragraph">I already know that, besides drinking nectar, these miniature birds also feed on a variety of insects. Could this one be finding some tiny creatures to eat on the blackberry? We continue to watch with curiosity as she hovers with agility and then zooms forward to probe another blackberry leaf. She’s clearly finding something that’s of interest.</p>



<p class="has-black-color has-text-color wp-block-paragraph">“[She] literally is just going one by one, checking everything,” says fellow birder Ross McLane.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">Ross keeps watching the hummingbird while I pull my camera out and manage to get photos of her behavior. After a few minutes, she zooms off, and I walk over to take a closer look at the blackberry leaves.</p>



<h3 class="wp-block-heading">The blackberries</h3>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="908" src="http://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_171800179.MP_-1024x908.jpg" alt="Himalayan blackberry (Rubus discolor) at Green Lake Park." class="wp-image-2233" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_171800179.MP_-1024x908.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_171800179.MP_-300x266.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_171800179.MP_-768x681.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_171800179.MP_.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Himalayan blackberry (Rubus discolor) at Green Lake Park.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Himalayan blackberries (<em>Rubus discolor</em>) first came to Seattle around 1900, after fruit breeder Luther Burbank brought them to California in hopes of starting a new fruit-growing industry. The blackberries &#8211; which Burbank dubbed “Himalayan” as a marketing gimmick (they’re actually native to Armenia and Iran) &#8211; became wildly successful. They spread extensively into natural areas around Seattle and all along the Pacific Coast, offering their large, tasty fruits to anyone who could pick them. But the success of the blackberries came at a cost. Their fearsomely thorny stems, which can arch higher than my head, have crowded out many of the native plants that once grew here.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">In Green Lake Park, a group called the <a href="https://greenseattle.org/" target="_blank" rel="noreferrer noopener">Green Seattle Partnership</a> is actively managing the Himalayan blackberry, removing patches of it by hand and replanting native species, such as goldenrod and red-flowering currant.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">To learn more about the blackberries and the restoration work, I interviewed Ash Lehto, who works as a Stewardship Coordinator for the nonprofit <a href="https://forterra.org/" target="_blank" rel="noreferrer noopener">Forterra</a> and is part of the Green Seattle collaboration.</p>



<p class="has-black-color has-text-color wp-block-paragraph">“Our relationship to blackberry is very complex in the Seattle area,” she told me.&nbsp;</p>



<h3 class="wp-block-heading">A complicated plant</h3>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="803" src="http://wildwithnature.com/wp-content/uploads/2023/04/PXL_20230315_171713210-1024x803.jpg" alt="A tangle of Himalayan blackberry along the edge of Green Lake." class="wp-image-2294" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/04/PXL_20230315_171713210-1024x803.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/04/PXL_20230315_171713210-300x235.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/04/PXL_20230315_171713210-768x602.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/04/PXL_20230315_171713210.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A tangle of Himalayan blackberry along the edge of Green Lake.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">On one hand, the blackberry acts like a &#8220;bully,&#8221; growing so fast and forming such dense thickets that it tends to push out other species. On the other hand, it’s a popular plant for wildlife. It provides cover for rabbits and manages to grow in some of the most inhospitable places in Seattle. And it&#8217;s not just rabbits that the blackberry supports.</p>



<p class="has-black-color has-text-color wp-block-paragraph">“Birds really like these plants &#8211; they like the flowers and they like the fruits,” Ash told me.</p>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="762" src="http://wildwithnature.com/wp-content/uploads/2023/03/PXL_20220814_170206343-1024x762.jpg" alt="Thimbleberry (Rubus parviflorus), one of the native plants whose tasty fruits offer similar benefits to those of Seattle's blackberries." class="wp-image-2235" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20220814_170206343-1024x762.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20220814_170206343-300x223.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20220814_170206343-768x572.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20220814_170206343.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Thimbleberry (Rubus parviflorus), one of the native plants whose tasty fruits offer similar benefits to those of Seattle&#8217;s blackberries.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">That&#8217;s why, whenever the Green Seattle group decides to remove a patch of Himalayan blackberry, they focus on replacing it with native plants that offer similar benefits (and also <a href="http://wildwithnature.com/2023/03/24/montana-native-plants-for-birds/" target="_blank" rel="noreferrer noopener">provide much better habitat for native insects</a>). Among these native plants, Ash mentions that salmonberry (<em>Rubus spectabilis</em>) and thimbleberry (<em>Rubus parviflorus</em>) offer summer fruits for people and wildlife. Snowberry (<em>Symphoricarpos</em> <em>albus</em>) fruits stick around through the winter, offering a later-season food source for the birds. Meanwhile, species like the red-flowering currant offer spring flowers for hummingbirds and bees.</p>



<p class="has-black-color has-text-color wp-block-paragraph">It&#8217;s not just about fruits and flowers, though. To feed the birds, insects are essential &#8211; and to support them, we need native plants. Ed Dominguez, Lead Naturalist at the <a href="https://sewardpark.audubon.org/" target="_blank" rel="noreferrer noopener">Seward Park Audubon Center</a> and another partner with Green Seattle, told me more about restoring bird habitat in Seattle&#8217;s urban parks. </p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;The indigenous plants are the ones the insects select,&#8221; Ed reiterated. And, once again, those same insects are critical food for migrating and nesting birds. </p>



<p class="has-black-color has-text-color wp-block-paragraph">Among some of Ed&#8217;s favorite native plants for restoration projects are beaked hazelnut (<em>Corylus cornuta</em>), osoberry (<em>Oemleria cerasiformis</em>), salal (<em>Gaultheria shallon</em>), and wild ginger (<em>Asarum caudatum</em>).</p>

<p class="has-black-color has-text-color wp-block-paragraph">In Green Lake Park, gradually removing many of the blackberries will benefit plant diversity &#8211; and the birds and insects. But in the meanwhile, this hummingbird is showing a lot of interest in the blackberry patch. Why?&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">Up close, the Himalayan blackberry leaves are rough, like sandpaper. They’re paler below, with a few curved prickles along the midrib. When I hold one up for a closer look, the sun shines through it, lighting up a fine pattern of reticulated veins.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph"><em>Was the hummingbird hunting aphids?</em> I wonder. But when I check the undersides of the leaves, I see neither aphids, nor other insects, nor anything else that catches my attention. The mystery remains.</p>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">When I catch up with the main group, I ask Roniq about the hummingbird’s behavior. Has she seen anything like this before?</p>



<p class="has-black-color has-text-color wp-block-paragraph">In addition to the insect-hunting idea, Roniq suggests spiderweb-gathering as another possible explanation. Anna’s hummingbirds commonly use spiderwebs &#8211; along with lichens and mosses &#8211; to construct their nests, she tells me. And for these year-round Pacific Northwest birds, the nesting season is already in full swing.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">“Anna’s hummingbirds nest earlier than a lot of other birds &#8211; they’ve been nesting since February,” Roniq continues.</p>



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

</div>


<p class="has-black-color has-text-color wp-block-paragraph">Indeed, even during my short visit to Seattle, the nesting of the hummingbirds has already become a common theme. A few days before, I found a nest in West Seattle’s <a href="https://www.seattle.gov/parks/allparks/schmitz-preserve-park" target="_blank" rel="noreferrer noopener">Schmitz Park</a>, an urban patch of old-growth forest that has survived a century and a half of logging and house-building. That day, it was the movement that showed me the nest: a tiny whirring flash of green as the Anna&#8217;s hummingbird dove from a branch towards the forest floor. As I watched carefully, she levitated towards the canopy once again. Then, suddenly, the movement stopped. And where she stopped was her nest, a tiny cup of mosses and lichens on top of a gently sloping alder branch.&nbsp;</p>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="834" src="http://wildwithnature.com/wp-content/uploads/2023/03/DSCN1779-1024x834.jpg" alt="Male Anna's hummingbird." class="wp-image-2239" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1779-1024x834.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1779-300x244.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1779-768x625.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1779.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Male Anna&#8217;s hummingbird.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">After Roniq mentions the spiderwebs, I take another look at my photos of that nest. Now that I’m paying attention, I can see the glint of the spider silk this female has woven through the wall of her nest.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">As I’ve started getting to know the plants and creatures of Seattle’s urban spaces, the Anna’s hummingbirds &#8211; like the Himalayan blackberries &#8211; are proving to be my frequent companions. Over the last half-century, these tiny, iridescent birds have become beloved residents of Seattle’s neighborhoods and gardens. (If you see a hummingbird in the city in mid-winter, before the migratory rufous hummingbirds return in March or April, it’s very likely this species.) But surprisingly, the Anna’s hummingbirds &#8211; like the vigorous blackberries that sprawl through Green Lake Park and greet multitudes of motorists along the I-5 &#8211; are relative newcomers to the area.&nbsp;</p>



<h3 class="wp-block-heading">Adapting to the urban landscape</h3>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="852" src="http://wildwithnature.com/wp-content/uploads/2023/03/DSCN1773-1024x852.jpg" alt="A male Anna's hummingbird visits willow (Salix sp.) flowers in Union Bay Natural Area." class="wp-image-2240" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1773-1024x852.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1773-300x250.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1773-768x639.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1773.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A male Anna&#8217;s hummingbird visits willow (Salix sp.) flowers in Union Bay Natural Area.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Anna’s hummingbirds arrived in Seattle in the 1960s. Originally they were birds of California’s coastal region, where they would start nesting when the late-winter rains triggered the blooming of the local currants (<em>Ribes </em>spp.). But with the growth of cities along the West Coast, these four-gram hummingbirds started finding that neighborhoods were an acceptable substitute for the southern California chaparral. Where houses, gardens, and hummingbird feeders had replaced the old-growth forests, Anna’s hummingbirds began to find a home in the urban landscape of the coastal Northwest. Now, just like Himalayan blackberry, Anna’s hummingbirds are a well-established part of Seattle’s urban landscape.&nbsp;</p>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">It’s just half an hour after we notice the Anna’s hummingbird probing the blackberry leaves in Green Lake Park that we find the day’s first hummingbird nest. Once again, it’s the female’s movements that show us the nest, a miniature cup resting on top of the horizontal branch of a white pine. She stays on her nest briefly, then departs again. On the other side of the paved trail from the white pine, 22 birders have their binoculars and cameras raised. Everything else is momentarily forgotten as we gape at the miniature nest, in awe of the magic of spring.</p>



<h3 class="wp-block-heading">Well-hidden nests</h3>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="960" src="http://wildwithnature.com/wp-content/uploads/2023/03/DSCN1748-1024x960.jpg" alt="The Anna's hummingbird nest in the white pine." class="wp-image-2242" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1748-1024x960.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1748-300x281.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1748-768x720.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1748.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">The Anna&#8217;s hummingbird nest in the white pine.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Even to sharp eyes, the nest blends in very well, a tiny cup on the branch of the white pine.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">“I have it now, but it took me forever to find it,” says Rayne Wilder.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Its sides are fluffy with what appears to be cattail down, blended with mosses, lichens, and the telltale glint of spiderwebs. If we hadn’t seen the hummingbird’s movement, we would have walked right past it without noticing.</p>



<p class="has-black-color has-text-color wp-block-paragraph">“It blows my mind that it’s so small,” says Ross McLane. “I can’t imagine there are babies in there.”</p>



<p class="has-black-color has-text-color wp-block-paragraph">Farther down the trail, someone notices another Anna’s hummingbird. This one is still in the middle of the nest-building process, carrying material to the spreading limb of a large Douglas-fir. It’s tempting to keep watching her: nest-building is a fascinating process. But it’s also an especially sensitive time for the birds, and Roniq encourages us all to move along and leave the hummingbird in peace.</p>



<p class="has-black-color has-text-color wp-block-paragraph">“We are in their territory, they’re not in ours,” she reminds us.</p>

<p class="has-black-color has-text-color wp-block-paragraph">It’s been an incredible morning at Green Lake, full of the exuberance of spring. The air around us has been filled with the melodies of the song sparrows and the occasional bubbling trills of a Pacific wren. But the puzzle of the Anna’s hummingbird and the blackberry remains. What was she doing?</p>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="769" src="http://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-1024x769.jpg" alt="A male Anna's hummingbird." class="wp-image-2246" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-1024x769.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-768x577.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-1536x1153.jpg 1536w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-2048x1538.jpg 2048w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">A male Anna&#8217;s hummingbird.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">I read more about Anna’s hummingbirds in<a href="https://birdsoftheworld.org/bow/home" target="_blank" rel="noreferrer noopener"> <em>Birds of the World</em></a>, a wonderful online reference full of painstaking detail about the biology of the birds around us. In terms of insect hunting, it’s somewhat common to see these hummers catching midges in mid-air. They’re also known to visit spiderwebs for insects, robbing the spiders&#8217; catch. And <a href="https://sora.unm.edu/sites/default/files/journals/condor/v058n06/p0393-p0405.pdf" target="_blank" rel="noreferrer noopener">in one California study</a>, researchers noticed that Anna’s hummingbirds often hunted whiteflies (family <a href="https://bugguide.net/node/view/7055" target="_blank" rel="noreferrer noopener">Aleyrodidae</a>) on blackberry leaves from April through mid-summer.</p>



<p class="has-black-color has-text-color wp-block-paragraph">So was the female we saw catching whiteflies or aphids, gathering spider silk for a nest, or doing something entirely unrelated? In the end, without directly observing what she was gathering, there’s no way to know for sure.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">When I mention the hummingbird to Ed Dominguez, though, he tells me that he has seen similar behaviors. Ed, who has much more experience with Seattle&#8217;s birds and blackberries than I do, thinks that she was most likely gathering spider silk &#8211; or possibly hunting spiders.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Spiders are a real delicacy for them,&#8221; he tells me. </p>



<p class="has-black-color has-text-color wp-block-paragraph">Ed frequently sees spiders on the Himalayan blackberry leaves. Aphids? Not so much. Come to think of it, that makes sense. Most of the world&#8217;s 4000+ aphid species <a href="https://www.sciencedirect.com/science/article/pii/S1631069110001095" target="_blank" rel="noreferrer noopener">are specialists on particular plants</a>. Around Seattle, then, we&#8217;re likely to find these specialist aphids on the native plants that they&#8217;ve coevolved with.</p>



<h3 class="wp-block-heading">Sparks of curiosity</h3>



<p class="has-black-color has-text-color wp-block-paragraph">It lasted just a few moments. An everyday mystery: in a tangle of blackberry in the middle of a massive city, an Anna&#8217;s hummingbird was behaving in a way I didn&#8217;t understand. This spark of curiosity led me towards some delightful and informative conversations with several of Seattle&#8217;s excellent naturalists. It led me towards more questions &#8211; and, eventually, towards a glimpse of the complicated dance between a non-native blackberry, a sort-of native hummingbird, some unseen spiders, some missing aphids, and the nuances of Seattle&#8217;s native plant restoration efforts. The puzzle of the hummingbird on the blackberry leaves was a reminder &#8211; like the well-hidden nests along Green Lake’s busy trail &#8211; that the world is complicated and wonderful. And by paying attention to the creatures around us, we can connect with that wonder &#8211; and with each other.</p>



<p class="has-black-color has-text-color wp-block-paragraph">So next time you find yourself around Anna’s hummingbirds and blackberries, keep your eyes open. Watch for foraging behaviors and check for signs of spider silk and tiny insects. And, if you’d like, let me know what you see.</p>

<p class="has-black-color has-text-color wp-block-paragraph">Cuando dejé Montana, cubierta en nieve, hace unos días para visitar a amigos en Seattle, Washington, fue una repentina transición desde las profundidades del invierno hasta la intensidad de la primavera. Hoy, el sol matutino está haciendo que las ramas plumosas de las tuyas gigantes (<em>Thuja plicata</em>) brillen suavemente con color verde. Ilumina un junco ojos negros (<em>Junco hyemalis</em>), trinando con euforia del sauce al borde del lago. En todas partes de Seattle, los dientes de león (<em>Taraxacum</em>) están emergiendo como manchas brillantes de luz solar entre los pastos.</p>

<p class="has-black-color has-text-color wp-block-paragraph">En medio de esta ciudad animada, el Parque Green Lake es un oasis de agua y plantas, tarareando con humanos y aves. Hay gente andando, corriendo y empujando cochecitos a lo largo del camino pavimentado que rodea este lago urbano. Patos chalcuán (<em>Mareca americana</em>) y gansos canadienses mayores (<em>Branta canadensis</em>) pastan en los céspedes. Gorriones cantores (<em>Melospiza melodia</em>) cantan desde las totoras (<em>Typha</em>) y las zarzas himalayanas (<em>Rubus discolor</em>) cerca de la orilla, y reyezuelos corona amarilla (<em>Regulus satrapa</em>) revolotean entre las ramas de los ayarines (<em>Pseudotsuga menziesii</em>), cazando minúsculos invertebrados. </p>



<p class="has-black-color has-text-color wp-block-paragraph">Hace unos días que los reyezuelos matraquita (<em>Corthylio calendula</em>) empezaron sus cantos primaverales acá. Ahora podemos escucharlos en todos lados del parque, las ceceadas notas iniciales del canto transformándose de repente en un animado crescendo.</p>

<p class="has-black-color has-text-color wp-block-paragraph">“Hace rato que ha sido primavera para las aves,” dice Roniq Bartanen.&nbsp;</p>



<p class="has-black-color has-text-color wp-block-paragraph">Roniq, una guía profesional a las aves (<a href="https://shebirds.com/" target="_blank" rel="noreferrer noopener">aprende más sobre su trabajo acá</a>), ha mirado las aves en Green Lake desde hace años. Hoy soy uno entre más de 20 personas que la están acompañando a ella en la excursión mensual gratuita que está guiando acá. Es una de las varias excursiones regulares que coordina el grupo <a href="https://seattleaudubon.org/" target="_blank" rel="noreferrer noopener">las Aves Conectan Seattle</a>. Esta organización &#8211; que visualiza y propone &#8220;ciudades donde las aves y la gente florezcan&#8221; &#8211; <a href="https://seattleaudubon.org/2023/03/28/a-new-name-for-an-inclusive-future/" target="_blank" rel="noreferrer noopener">recientemente cambió su nombre</a>, que previamente era Seattle Audubon.

</div>


<p class="has-black-color has-text-color wp-block-paragraph">En el Parque Green Lake, las plantas también nos están contando sobre la conexión con las aves. El grosellero rojo (<em>Ribes sanguineum</em>) está en plena floración, los manojos de flores de rosa profunda contrastando con las hojas texturizadas que ya se están desplegando. Roniq dice que, en este ecosistema litoral, el grosellero está entre las más tempranas de las plantas nativas en florecer. En su jardín, el grosellero ya ha estado floreciendo por un mes. Los colibríes cabeza roja (<em>Calypte anna</em>) &#8211; los cuales se quedan en Seattle a lo largo del invierno &#8211; a menudo visitan estas llamativas flores rosas. En poco tiempo, los altamente migratorios zumbadores canelos (<em>Selasphorus rufus</em>) van a unirse con los colibríes cabeza roja cerca de los groselleros cuando los zumbadores &#8211; viajeros de larga distancia &#8211; regresen de sus hogares invernales en México.</p>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">Durante nuestra caminata, vemos señales de la primavera en todos lados. No sólo consisten en las flores de los dientes de león o los groselleros rojos. También vemos un par de sastrecillos (<em>Psaltriparus minimus</em>) empezando a construir su nido colgante, que se parece a un calcetín, en una tuya gigante. Una garza morena (<em>Ardea herodias</em>) que vadea en los bajíos muestra las largas plumas ornamentales de la estación reproductiva. En algún momento, veo un carbonero cabecinegro (<em>Poecile atricapillus</em>) desapareciendo en el extremo de una rama en descomposición de abedul, donde parece que tiene su nido.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Esta es la temporada en la que las hormonas están altas, así que las aves están moviéndose de prisa&#8230; uno persigue al otro; construyen sus nidos,&#8221; dice Roniq.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Es una temporada emocionante para estar acá, compartiendo el asombro de la estación.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Me encuentro yendo a la zaga tras la mayor parte del grupo, yo fácilmente distraído por conversaciones y tantas aves. Estoy con algunas personas, andando despacio, cuando vemos una colibrí cabeza roja hembra haciendo algo que me sorprende. Ella se cierne en el aire cerca de un enredado parche extendido de zarzas himalayanas cerca del borde del agua. Mientras la miramos, ella se mueve metódicamente de una hoja a la siguiente, sondando los bordes de las partes inferiores con su pico delgado.</p>



<h3 class="wp-block-heading">El misterio del colibrí cabeza roja</h3>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">Los colibríes son bien conocidos por alimentarse con néctar de las flores&#8230; pero las zarzas aún no están cerca de florecer. Entonces ¿qué hace ella?</p>



<p class="has-black-color has-text-color wp-block-paragraph">Ya sé que, además de libar néctar, estas aves miniaturas también se alimentan de una variedad de insectos. ¿Podría ser que ésta esté encontrando unas criaturas minutas para comer en la zarza? Seguimos mirándola con curiosidad mientras que se cierne ágilmente y entonces avanza para sondar otra hoja de zarza. Es claro que ella está encontrando algo que le interesa.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;[Ella] literalmente está yendo de una hoja a la otra, revisando todo,&#8221; dice Ross McLane, uno de mis compañeros de pajarear hoy.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Ross sigue mirando el colibrí mientras saco mi cámara y logro tomar unas fotos de su comportamiento. Después de pocos minutos, ella vuela adelante, y me acerco a las zarzas para examinar las hojas.</p>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">Las zarzas himalayanas (<em>Rubus discolor</em>) originalmente vinieron a Seattle cerca de 1900, después de que Luther Burbank, un cultivador de frutas, las trajo a California. Él esperaba crear una nueva industria cultivando frutas para el mercado de envío. Las zarzas &#8211; a las cuales Burbank les dio el apodo &#8220;himalayana&#8221; como una estrategia de comercialización (realmente son autóctonas a Armenia e Irán) &#8211; se volvieron muy exitosas. Se extendieron por áreas naturales a lo largo de la Costa Pacífica e incluso cerca de Seattle, ofreciendo sus sabrosas frutas grandes a todos que quisieran cosecharlas. Pero el éxito de las zarzas también implicó algunas desventajas. Sus tallos terriblemente espinosos, los cuales pueden hacer un arco más alto que mi cabeza, han desbancado muchas de las plantas nativas que una vez crecían acá.</p>



<p class="has-black-color has-text-color wp-block-paragraph">En el Parque Green Lake, un grupo que se llama la <a href="https://greenseattle.org/" target="_blank" rel="noreferrer noopener">Green Seattle Partnership</a> está activamente manejando la zarza himalayana. Remueve la zarza manualmente y replanta especies nativas, tales como la vara de oro (<em>Solidago</em>) y el grosellero rojo.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Para aprender más sobre las zarzas y el trabajo de restauración, entrevisté a Ash Lehto. Ella trabaja como Coordinadora de Gestión para la organización sin fines de lucro <a href="https://forterra.org/" target="_blank" rel="noreferrer noopener">Forterra</a> y participa en la colaboración de Green Seattle.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Nuestra relación con la zarza es muy compleja en la comarca de Seattle,&#8221; me dijo.</p>



<h3 class="wp-block-heading">Una planta complicada</h3>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="762" src="http://wildwithnature.com/wp-content/uploads/2023/03/PXL_20220814_170206343-1024x762.jpg" alt="Thimbleberry (Rubus parviflorus), one of the native plants whose tasty fruits offer similar benefits to those of Seattle's blackberries." class="wp-image-2235" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20220814_170206343-1024x762.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20220814_170206343-300x223.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20220814_170206343-768x572.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20220814_170206343.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption"><em>Rubus parviflorus</em>, una planta nativa cuyas sabrosas frutas ofrecen beneficios similares a las de las zarzas de Seattle.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Por una parte, la zarza actúa como un &#8220;matón,&#8221; creciendo tan rápidamente y formando matorrales tan densos que suele desplazar otras especies. Por otra parte, es una planta popular para la vida silvestre. Provee abrigo para los conejos. Logra crecer en algunos de los lugares menos hospitalarios de Seattle. Y no sólo son los conejos que la zarza mantiene.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;A las aves les gustan mucho estas plantas &#8211; las flores y las frutas,&#8221; me dijo Ash.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Por eso, cuando el grupo Green Seattle decide remover un parche de la zarza himalayana, se concentra en reemplazarlo con plantas nativas que ofrecen ventajas similares. (Estas plantas nativas también <a href="http://wildwithnature.com/2023/03/24/montana-plantas-nativas-para-aves/" target="_blank" rel="noreferrer noopener">proveen un hábitat mucho mejor para los insectos nativos</a>.) Entre esas plantas nativas, Ash menciona que las frambuesas <em>Rubus spectabilis</em> y <em>Rubus parviflorus</em> ofrecen frutas veraniegas para la gente y la vida silvestre. Las frutas de la perlita (<em>Symphoricarpos</em> <em>albus</em>) permanecen por el invierno, ofreciendo entonces alimento para las aves. Entretanto, especies como el grosellero rojo ofrecen flores primaverales para los colibríes y las abejas.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Sin embargo, la restauración no sólo tiene que ver con las frutas y las flores. Para alimentar las aves, los insectos son esenciales. Y para mantenerlos, necesitamos las plantas nativas. Ed Dominguez, naturalista principal en el <a href="https://sewardpark.audubon.org/" target="_blank" rel="noreferrer noopener">Seward Park Audubon Center</a> y otro colaborador de Green Seattle, me contó más sobre cómo restaurar el hábitat para aves en los parques urbanos de Seattle.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Las plantas indígenas son las que escogen los insectos,&#8221; reiteró. Y, otra vez, los insectos son un alimento crucial para las aves migratorias y reproductivas.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Entre sus plantas favoritas para la restauración están la avellana (<em>Corylus cornuta</em>), la <em>Oemleria cerasiformis</em>, la <em>Gaultheria shallon</em> y el jengibre silvestre (<em>Asarum caudatum</em>).</p>



<h3 class="wp-block-heading">El comportamiento del colibrí cabeza roja</h3>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">En el Parque Green Lake, remover muchas de las zarzas poco a poco va a beneficiar la diversidad de plantas &#8211; y las aves e insectos. Pero mientras tanto, este colibrí está mostrando mucho interés en el parche de zarza. ¿Por qué?</p>



<p class="has-black-color has-text-color wp-block-paragraph">De cerca, las hojas de la zarza himalayana son ásperas, como lija. Las partes inferiores son más pálidas, con unas espinas curvadas ubicadas a lo largo de la vena media. Cuando levanto una hoja para verla más atentamente, el sol brilla por ella, iluminando un patrón intrincado de venas reticuladas.</p>



<p class="has-black-color has-text-color wp-block-paragraph"><em>¿Cazaba el colibrí áfidos?</em> me pregunto. Pero cuando reviso las partes inferiores de las hojas, no veo ni áfidos ni otros insectos ni nada más que llama la atención. El misterio permanece.</p>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="788" src="http://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_171841305.MP_-1024x788.jpg" alt="The underside of one of the Himalayan blackberry leaves where the Anna's hummingbird was probing." class="wp-image-2237" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_171841305.MP_-1024x788.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_171841305.MP_-300x231.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_171841305.MP_-768x591.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/PXL_20230315_171841305.MP_.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">La parte inferior de una de las hojas de la zarza himalayana en la que el colibrí cabeza roja investigaba.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">Cuando alcanzo al resto del grupo, le pregunto a Roniq sobre el comportamiento del colibrí. ¿Ella ha visto algo así antes?</p>



<p class="has-black-color has-text-color wp-block-paragraph">Además de mi idea de que el colibrí tal vez cazaba insectos, Roniq sugiere que podría ser que recogía telarañas. Los colibríes cabeza roja a menudo usan telarañas &#8211; junto con líquenes y musgos &#8211; para construir sus nidos, me dice ella. Y para estas aves que viven todo el año en el Pacific Northwest, la estación reproductiva ya está acá.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Los colibríes cabeza roja anidan más temprano en el año que muchas otras aves &#8211; han estado anidando desde febrero,&#8221; explica Roniq.&nbsp;</p>

<p class="has-black-color has-text-color wp-block-paragraph">De hecho, incluso durante mi visita corta a Seattle, la anidación de los colibríes ya se ha vuelto un tema común. Hace unos días que hallé un nido en el Parque Schmitz de West Seattle, un parche urbano del bosque antiguo que ha sobrevivido un siglo y medio de tala y edificación. Ese día, fue el movimiento que me mostró el nido. Vi un pequeño destello de verde mientras el colibrí zumbó desde una rama hacia el suelo forestal. Miré atentamente mientras que ella levitó otra vez hacia el dosel. Entonces, de repente, el movimiento se detuvo. Y donde ella se paró estaba su nido, una diminuta taza de musgos y líquenes sobre la rama suavemente inclinada de un aliso.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Hoy, después de que Roniq menciona las telarañas, echo otro vistazo a mis fotos de ese nido. Y ya que estoy mirándolo con atención, puedo ver el reflejo de la seda de araña que esta hembra ha tejido por el muro de su nido.</p>

<p class="has-black-color has-text-color wp-block-paragraph">Mientras he empezado a conocer las plantas y criaturas de los espacios urbanos de Seattle, ha resultado que los colibríes cabeza roja &#8211; así como las zarzas himalayanas &#8211; me están acompañando frecuentemente. Estas pequeñitas aves iridiscentes se han vuelto residentes queridos de los vecindarios y jardines de Seattle. (Si ves un colibrí en esta ciudad en pleno invierno, antes de que los zumbadores canelos regresen en marzo o abril, es muy probable que sea de esta especie.) Pero sorprendentemente, estos colibríes &#8211; como las zarzas vigorosas que se tumban por el Parque Green Lake y que les dan la bienvenida a los conductores a lo largo del I-5 &#8211; han llegado más o menos recientemente.</p>



<h3 class="wp-block-heading">Adaptándose al paisaje urbano</h3>

<p class="has-black-color has-text-color wp-block-paragraph">Los colibríes cabeza roja llegaron a Seattle en los años 1960. Originalmente eran aves de la región costera de California, donde solían comenzar a anidar cuando las lluvias al fin del invierno impulsaban la floración de los groselleros locales (<em>Ribes</em> spp.). Pero con el crecimiento de ciudades a lo largo de la Costa Oeste, estos colibríes de cuatro gramos empezaron a descubrir que los vecindarios urbanos eran un sustituto aceptable al chaparral del sur de California. Donde las casas, comederos de colibríes y jardines habían reemplazado los bosques antiguos, los colibríes cabeza roja empezaron a acostumbrarse al paisaje urbano del Noroeste costero. Ahora los colibríes cabeza roja, así como la zarza himalayana, son una parte bien establecida del paisaje urbano de Seattle.</p>

</div>


<p class="has-black-color has-text-color wp-block-paragraph">Sólo media hora después de ver el colibrí cabeza roja sondando las hojas de la zarza, hallamos el primer nido de colibrí de este día. Otra vez, son los movimientos de la hembra que nos lo muestran, una taza pequeñita sentada sobre una rama horizontal de un pino blanco. Ella se queda brevemente en el nido y luego se va. Al otro lado del camino pavimentado, hay 22 pajareros con los binoculares y cámaras levantados. Por un momento olvidamos todo lo demás mientras miramos boquiabiertos al nido diminuto. Estamos asombrados por la magia de la primavera.</p>



<h3 class="wp-block-heading">Nidos bien escondidos</h3>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="960" src="http://wildwithnature.com/wp-content/uploads/2023/03/DSCN1748-1024x960.jpg" alt="The Anna's hummingbird nest in the white pine." class="wp-image-2242" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1748-1024x960.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1748-300x281.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1748-768x720.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1748.jpg 1200w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">El nido del colibrí cabeza roja en el pino blanco.</figcaption></figure>
</div>


<p class="has-black-color has-text-color wp-block-paragraph">El nido se esconde muy bien &#8211; hasta de personas con los ojos agudos &#8211; una pequeña taza sobre la rama del pino blanco.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Lo veo ahora, pero me tomó mucho tiempo hallarlo,&#8221; dice Rayne Wilder.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Los lados del nido son peludos con lo que parece ser plumón de totora, mezclado con musgos, líquenes y el destello revelador de las telarañas. Si no hubiéramos visto el movimiento del colibrí, habríamos andado adelante completamente ajenos a la presencia del nido.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Me asombra que sea tan pequeño,&#8221; dice Ross McLane. &#8220;No puedo imaginarme que haya bebés adentro.&#8221;</p>



<p class="has-black-color has-text-color wp-block-paragraph">Más adelante en la caminata, alguien se da cuenta de otro colibrí cabeza roja. Esta hembra aún está en el proceso de construir su nido, llevando materiales a la rama grande de un ayarín. Es tentador seguir mirándola: la construcción de un nido es un proceso fascinante. Pero también es un tiempo muy sensible para las aves, y Roniq nos anima a seguir adelante y dejarla en paz.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Estamos en sus territorios, no están en los nuestros,&#8221; ella nos recuerda.</p>

<p class="has-black-color has-text-color wp-block-paragraph">Ha sido una mañana increíble en Green Lake, llena de la euforia de la primavera. El aire ha estado lleno de las melodías de los gorriones cantores y los efervescentes trinos esporádicos de un saltapared cholino del oeste (<em>Troglodytes pacificus</em>). Pero el rompecabezas del colibrí cabeza roja en las zarzas permanece. ¿Qué hacía ella?</p>


<div class="wp-block-image is-resized">
<figure class="alignright size-large"><img loading="lazy" decoding="async" width="1024" height="769" src="http://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-1024x769.jpg" alt="A male Anna's hummingbird." class="wp-image-2246" style="width:500px" srcset="https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-1024x769.jpg 1024w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-300x225.jpg 300w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-768x577.jpg 768w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-1536x1153.jpg 1536w, https://wildwithnature.com/wp-content/uploads/2023/03/DSCN1781-2048x1538.jpg 2048w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption class="wp-element-caption">Un colibrí cabeza roja macho.</figcaption></figure>

<p class="has-black-color has-text-color wp-block-paragraph">Leo más sobre los colibríes cabeza roja en <a href="https://birdsoftheworld.org/bow/home" target="_blank" rel="noreferrer noopener"><em>Birds of the World</em></a>, una maravillosa fuente en línea llena de minuciosos detalles sobre la biología de las aves alrededor de nosotros. En términos de cazar insectos, aprendo que es más o menos común ver estas aves pequeñas atrapando jejenes en pleno vuelo. También son conocidos por visitar telarañas para robar los insectos atrapados allá. Y <a href="https://sora.unm.edu/sites/default/files/journals/condor/v058n06/p0393-p0405.pdf" target="_blank" rel="noreferrer noopener">en un estudio de California</a>, los investigadores notaron que los colibríes cabeza roja cazaban mosquitas blancas (<a href="https://bugguide.net/node/view/7055" target="_blank" rel="noreferrer noopener">Aleyrodidae</a>) en las hojas de las zarzas desde abril hasta medio verano.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Entonces, ¿la hembra que vimos estaba cazando mosquitas blancas o áfidos, recogiendo telarañas para un nido o haciendo algo completamente diferente? Finalmente, sin observar directamente lo que recogía, no podemos resolver esta pregunta con certeza.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Pero cuando le menciono el colibrí a Ed Dominguez, me dice que ha visto comportamientos parecidos. Ed cree que ella probablemente estaba recogiendo telarañas &#8211; o talvez cazando las propias arañas.</p>



<p class="has-black-color has-text-color wp-block-paragraph">&#8220;Las arañas son un manjar para ellos,&#8221; me dice.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Él a menudo ve arañas bajo las hojas de las zarzas himalayanas. ¿Áfidos? No tanto. Y cuando lo pienso más, eso tiene sentido. La mayoría de las más de 4.000 especies de áfidos en el mundo son especialistas en plantas particulares. Por eso, cerca de Seattle, es más probable que veamos estos áfidos especialistas en las plantas nativas con las que han coevolucionado.</p>



<h3 class="wp-block-heading">Chispas de curiosidad</h3>



<p class="has-black-color has-text-color wp-block-paragraph">Sólo duró unos momentos. Fue un misterio cotidiano: en un matorral de zarza en medio de una ciudad masiva, un colibrí cabeza roja hacía algo que yo no entendí. Esta chispa de curiosidad me llevó a algunas conversaciones encantadoras e informativas con unos de los naturalistas excelentes de Seattle. Me llevó hacia más preguntas &#8211; y, al final, hacia un vistazo del baile complejo entre una zarza no nativa, un colibrí casi nativo, algunas arañas inadvertidas, algunos áfidos ausentes y los matices de los esfuerzos para restaurar plantas nativas en Seattle. El rompecabezas del colibrí en las hojas de zarza me recordó &#8211; así como los nidos bien escondidos a lo largo del camino concurrido en Green Lake &#8211; que el mundo es complicado y maravilloso. Y por darnos cuenta de las criaturas cerca de nosotros, podemos conectarnos con este asombro &#8211; y con otra gente.</p>



<p class="has-black-color has-text-color wp-block-paragraph">Entonces, la próxima vez que estés cerca de los colibríes cabeza roja y las zarzas, mantén los ojos abiertos. Está atento a colibríes buscando comida. Revisa en las hojas señales de telarañas o insectos minúsculos. Y, si quieres, dime lo que ves.</p>
