• Oakland herons released at MLK Shoreline

    By Ilana DeBare
    Our three-way heron rescue partnership with International Bird Rescue and Oakland Zoo paid inspiring dividends again on Friday, when 19 young herons and egrets were released into thriving marsh habitat at Martin Luther King Jr. Regional Shoreline.
    There is hardly anything more uplifting than witnessing the release of wild birds that had been threatened with death, rescued, and nursed back to health. Watching them stick a tentative bill out of the door of their carrying case… take a step or two… then raise their wings and burst into flight… finally settling into the muddy water to start foraging for food….
    The scene was made even more meaningful by the knowledge that this marsh had been saved from development by a Golden Gate Bird Alliance lawsuit in the 1980s. Thanks to advocacy by GGBA and our allies, it is now home to endangered species like Ridgway’s Rails and a welcoming site for this new batch of rescued birds. GGBA volunteers and Eco-Ed students do habitat restoration there on an ongoing basis.

    “We are so fortunate to have the world-class expertise of International Bird Rescue here in our backyard,” said Cindy Margulis, Executive Director of Golden Gate Bird Alliance. “Thanks to Bird Rescue’s skilled and dedicated care, these birds now have a chance to be wild, healthy birds.”
    Golden Gate Bird Alliance organized the three-way rescue partnership in 2016 to save the lives of young birds in Oakland, where more than 150 Snowy Egret and Black-crowned Night-Heron nests occupy thick-canopied ficus trees over busy streets in the city’s urban core. Young birds that had not yet fledged often fell from the trees, breaking bones on the concrete sidewalk or wandering into deadly traffic.
    Both in 2016 and this spring, GGBA volunteers monitored the area for fallen birds. Oakland Zoo collected the injured birds and offered immediate veterinary care. Then Bird Rescue provided long-term rehabilitation at their renowned S.F. Bay-Delta Wildlife Center in Fairfield.
    In total, 63 Oakland herons and egrets received care during this year’s nesting season.…

  • Falcon fledge watch at UC Berkeley

    By Christina Tarr
    In spring, the U.C. Berkeley campus is a veritable nursery. I walk across campus almost daily, and have regularly seen baby juncos, phoebes, crows, Brown Creepers, and Red-shouldered Hawks, not to mention skunks and raccoons. This spring, though, the most exciting family by far were the Peregrine Falcons nesting on top of the Campanile, the 307-foot bell tower in the middle of campus. The two chicks, named Fiat and Lux, fledged during the first week of July.
    While peregrines have overwintered on the Campanile, as far as we know they have never nested there before this. But now that they have successfully nested there once, they will likely return in years to come.
    Because I work on campus, I was lucky enough to be able to hang out intermittently with the volunteer “fledge watch” for most of the week. First, we assembled equipment, boxes, and a net, in case we had to catch a bird on the ground. We posted signs around the area, telling people what to do and whom to call if they found a bird on the ground. The watchers started each day by 7 a.m. in a little patio near the northwest corner of the plaza surrounding the Campanile, scopes trained on the tower. Around 11, when the fog burned off and the sun came out, they moved to a shaded spot near Evans Hall, directly north of the tower. As the day wore on, they moved to the west side, near South Hall, or back to the little plaza south of the library. They stayed until dark, typically wrapping up about 8:30 or 9 p.m.

    The birds spent long periods of time doing not very much. The parents flew in and out, bringing food to the hungry and noisy chicks. They sat on the tower keeping watch over things. They liked the corners, the tops of the light stands, and the top of the cupola. The mother in particular spent a lot of time sitting on the decorative carved garland directly below the balcony level where the chicks were. The mother screamed. The chicks screamed. Occasionally, more and more often as time went on, we could see the babies poke their heads out between the decorative fleurs de lis that made up the railing around the balcony.…

  • Oakland saves herons while removing nest tree

    By Ilana DeBare
    What a difference three years makes!
    In spring 2014, Oakland post office officials thoughtlessly decided to cut foliage in the Bay Area’s largest heron rookery at the height of nesting season — destroying nests and leaving young birds injured and homeless.
    This week, the City of Oakland had to remove a hazardous tree in that same rookery. But city staff partnered with Golden Gate Bird Alliance and International Bird Rescue in a humane, well-planned initiative to ensure that birds, eggs, and nests were protected.
    THANK YOU to Oakland city staff — especially the folks in Animal Control; the Creeks, Watershed & Stormwater division; Tree Services; Traffic Control and Maintenance; and Drainage Maintenance!

    Here’s the full story:
    Over the past decade or so, the leafy ficus trees lining the streets near Alice and 13th Streets became home to the Bay Area’s largest nesting colony of Black-crowned Night-Herons and Snowy Egrets. Over 150 pairs of birds nest and raise young in the thick canopy, foraging for fish and other prey at nearby Lake Merritt and the Oakland Estuary.
    The colony received little public attention until the disastrous tree trimming incident in 2014, which made national headlines.
    In the wake of the trimming debacle, Golden Gate Bird Alliance launched a multi-year campaign to protect and educate the public about these dramatic-looking birds.
    The problem went deeper than thoughtless tree trimming. The street trees are a dangerous nesting site: Young, not-yet-fledged birds that fall from the branches face broken bones on the hard concrete and deadly automobile traffic.
    In 2015, we mounted an educational campaign with volunteer docents leading tours of the rookery, multi-lingual posters in nearby storefronts, a bilingual brochure on bird-friendly tree care, and a chalk art “flash mob” creating sidewalk art about the herons.
    In 2016, we created a three-way rescue partnership with Oakland Zoo and International Bird Rescue. GGBA volunteers monitored the area for fallen birds; Oakland Zoo technicians provided speedy rescue and triage; then IBR provided long-term rehab and release into more suitable wild habitat along the Bay.
    This year we continued that partnership. And two weeks ago, when one of the large rookery trees suddenly split in half and fell, GGBA, Oakland Zoo, and IBR all joined Oakland city staff in an emergency effort to rescue young birds from the fallen jungle of branches and leaves.…

  • Blackbird fly! (off of my horse trailer)

    By Eric Schroeder
    As a horse owner dependent upon a trailer to get into our local parks in the spring, I am vigilant about the trailer’s readiness. My trailer lives at Hossmoor, a 138-acre horse property where I’ve seen over fifty species of birds. It’s also just an eight-minute drive from Briones Regional Park—an excellent place to ride and to bird year-round.
    But this spring my horse had been injured and I let down my guard. Walking by the trailer in April,, I noticed that what we trailer owners fear most had happened—a Brewer’s Blackbird was sitting on a nest she had built on the spare battery compartment under the gooseneck of my trailer.
    I thought to myself that if she hadn’t yet laid any eggs, I could remove the nest—maybe put it on somebody else’s trailer that wasn’t in use. I approached, the bird flew the nest, and I poked my head in. Four eggs.
    Why my trailer? There were 25 other trailers that bird could have chosen! I realized immediately I wouldn’t be using the trailer for a while, even when my horse was sound again. But just how long would that be? On the west coast where Brewer’s Blackbirds are non-migratory, they start pairing up as early as the third week in January and all birds are paired by the second week in February. (I realize now that I should have been checking my trailer earlier—and regularly!—since females built the nests over a nine-day period.)

    Generally, eastern populations of Brewer’s Blackbirds tend to nest on the ground, while western populations built nests in a wide variety of locations—in bushes, in vegetation over water, in vegetable crops, and on available trailer perches. Nests built above ground tend to be built from twigs and weed stems with the rougher outer construction giving way to finer materials around the bowl. Bowls are often lined with horsehair—lots of that where my blackbirds live!

    Brewer’s Blackbirds are synchronous nesters, meaning that nest building for an entire colony starts at the same time. (If I had been paying closer attention to the blackbirds as a whole population, this wouldn’t have happened!) I discovered the eggs in early April but I didn’t have any idea how long they had been there (or when I might use my trailer again).…

  • Eco-Ed students discover wild San Francisco

    By Sharon Beals
    An energetic and slightly raucous hike up the trail through the canyon was just what the classroom of fourth graders from Bayshore Elementary in San Francisco’s Visitacion Valley neighborhood needed after their morning bus ride to Glen Park.
    The air was fresh, newly green willows blazed, and Islais Creek was brimming. In no time Anthony DeCicco, Golden Gate Bird Alliance’s Eco-Education organizer, leader, and magician, was demonstrating to half of these explorers how to net the aquatic life in its pools. GGBA volunteers handed out binoculars to the others, patiently demystified the art of focusing, and then led them off on a stop-and-start wander around the canyon to look, listen, and identify who was singing, flitting, or soaring.
    This stellar day was living embodiment of what they had been learning through GGBA’s school-based Eco-Ed program about the habitat and health of their local watershed, from the trickle of its headwaters through its journey to the ocean.

    Each year, working with classroom teachers and dedicated GGBA volunteers, this program reaches over 650 third, fourth, and fifth graders in underserved public elementary schools in East Oakland, North Richmond/San Pablo and southeast San Francisco. In a curriculum that integrates STEM (science/technology/engineering/math) learning standards, students learn about and help restore local wildlife habitats. At the end of the school year, the children and their families are invited on a culminating field trip, usually to the ocean. (For their final trip, this particular class went to Alcatraz to view the nesting colonies of cormorants, gulls, egrets, and Pigeon Guillemots.)

    The curiosity and enthusiasm of the students for the life they observed under microscopes and through binoculars that day in March was contagious. For many of them, a day in the wilds of even an urban park was a rare experience.
    The Eco-Education Program strives to improve the lives and learning of students from communities with limited access to environmental education, as well as few opportunities to spend time in nature. Within heavily industrialized communities stressed by limited resources and high crime rates, these trips offer children and family members opportunities to find a calming sanctuary within their nearby natural spaces.…
