• Birding the Bay Islands: Thriving in Angel Island’s diverse habitats

    By Helen J. Doyle and Evan Weissman

    We met at 6:30, as we agreed the night before. The sky was already light, a week before the summer solstice, though a layer of ocean fog gave everything a slightly hazy outline and dulled gray tone. June gloom. Summer on the San Francisco Bay. We parked where the road had been washed out by winter storms, listening for birds in the light morning breeze.

    We passed through oak woodlands and coastal scrub/chaparral habitats. Further along, a small grove of coast redwoods, planted a hundred years ago or more. All these habitats on a small island in the San Francisco Bay. We took a few steps, stopped and listened again, peering into the scrub for a flash of color or motion in the muted light. We heard one, two, three birds, several different species, on one side of the trail and then the other. Quietly, patiently, we listened.

    Angel Island has at least seven distinct habitats for its avian life, packed into one square mile: oak woodland, coastal scrub/chaparral, introduced Eucalyptus and Monterey Pine, a small Redwood grove, shoreline, and of course the surrounding bay waters and sky above. For those new to birding, the Island offers the chance to see a diversity of birds on easy walks through varied habitats (don’t forget to bird from the ferry!).

    Angel Island may delight experienced birders too. While none of these habitats are unique to the island, the type and number of birds differs from what you might see elsewhere. The oaks appear to support more Acorn Woodpecker families than a similarly sized woodland would elsewhere, perhaps because the birds are not competing with squirrels, who don’t live on Angel island. There are no California Towhees, common in the Bay Area, but there may be more Spotted Towhees than expected, perhaps due to reduced competition from their California Towhee relatives. And there seem to be more Pygmy Nuthatches. It’s unclear why the island has so many of these adorable birds, but we certainly aren’t complaining! Angel Island has surprisingly few shorebirds, perhaps due to a lack of healthy mudflats or tide pools, although one spotted sandpiper is often seen on its own, doing its characteristic butt-pump. And as opposed to Alcatraz–the Bay’s most infamous island–there are almost no waterbirds nesting on the ground or in shrubs, since Angel Island has rats, raccoons, and coyotes, mammalian predators that are absent from Alcatraz.…

  • Hope: A Lesson from the Birds

    By Jess Beebe

    Pine Siskin by Elizabeth Winstead

    Birds are wonderful ambassadors for the beauty of the world. As a member of the GGBA community, you are already charmed by the grace of flight, the miracle of migration, the curiosity in an avian eye. Yet, as with any great love, once we fall for birds, our hearts can be troubled and even broken. We hear how climate change and habitat loss are harming birds, and we feel a deep distress that we are losing something we love and are powerless to help. To protect ourselves, our psyche may throw a blanket of numbness over the anxiety, grief, or anger we feel. We focus on everyday tasks and ignore the rumble of unease.

    The truth behind the fog of protective denial may feel too heavy to face. Any action we take may seem hopeless given the enormity of the problem. What are we to do? Joanna Macy’s Work That Reconnects offers us a way forward. Based in Buddhism, deep ecology, and systems theory, the work is arranged in a spiral of four stages: grounding in gratitude, honoring our pain for the world, seeing with new eyes, and going forth. We can move through the spiral as often as we like to reconnect with what Macy calls “active hope”—a clear-eyed determination to engage in healing the world.

    Grounding in gratitude

    The first time I grasped what Macy means by gratitude, I was listening to the dawn chorus on an April morning in Point Reyes. Birdsong burst from every tree, and in an instant, I understood gladness to be the animating force of the universe: life loving life. It is our birthright as humans to feel this joy and vitality too. 

    Our experience of gladness helps us notice what is truly satisfying—not consuming luxuries, but enjoying the outdoors and relaxing with family and friends—and feel an easy gratitude that transcends the alienating transactionality of modern life and the accompanying sense that we are always in debt. It’s fortunate that we have birdsong to remind us every morning of what really matters: the elemental joy of belonging in the living world. We return to gratitude as the foundation of our resilience and commitment to life.

    Honoring our pain

    It’s painful to contemplate the loss of a species that defines home, as the Oak titmouse does for me. When I imagine springtime without that zerpeet, zerpeet, zerpeet, I want to crawl back under the blanket of denial.…

  • Light Pollution on Bird Migration Behavior

    By Lydia Bruno

    As urban dwellers, we are only too familiar with the effects of light pollution. Rarely can we see stars at night and often we have to travel to remote locations to even glimpse the wondrous Milky Way. Add to that, studies show light pollution can disrupt our circadian rhythms, affecting our ability to get a good night’s rest.

    A recent 2023 study published in Nature Communications, Artificial Light at Night is a Top Predictor of Bird Migration Stopover Density (Horton et al.),  outlined how light pollution also significantly impacts birds, especially during migration. This is particularly relevant to San Francisco as the Pacific Flyway, a major migratory route, includes the San Francisco Bay Area. An estimated billion birds travel through this flyway during spring and fall migratory seasons. The majority of these migrants are songbirds and they take flight primarily at night. Skyglow, or the artificial brightening of the night sky by light pollution, affects their nighttime migration by increasing stopover. 

    What is stopover? Like it sounds, stopover is the act of stopping over a place, essentially a rest stop along the birds’ epic journey, a pause to refuel, rest or take refuge from adverse weather conditions. This is an important and necessary part of their journey. However, due to habitat changes, with many areas becoming drier, less forested and brighter at night, historic stopover locations are at risk. 

    Along the Pacific Flyway, skyglow was found to be the top driver of stopover in an area. While this may at first seem positive, there are in fact, negative consequences depending on where the stopover occurs. Urban areas, like San Francisco, generate more skyglow than less populated areas and can become ecological traps, luring birds to areas where they are at greater risk of colliding with buildings,predation, and potentially throwing them off course, disconnecting them from their migratory path.. 

    The next step for researchers is to determine whether stopover hotspots are truly important ecological locations, the effect of skyglow luring the birds to the area or a combination of both.

    What we do know is, with light pollution increasing at a disconcerting 10% per year in North America, we need to invest in advocacy, collaboration and policy change to decrease this trend and reduce skyglow.

    How can you help? There are simple actions we can all take, including turning off unnecessary indoor and outdoor lights at night, closing blinds/curtains after dark, using warm colored LED bulbs (as bluer colored light has larger reach and worsens skyglow) and using dimmers and timers to minimize light usage.…

  • Birdathon 2024 – Our Most Successful Fundraiser Ever

    By Sharol Nelson-Embry, Birdathon 2024 co-chair

    Over the last couple of months, we held our largest annual fundraiser, Birdathon, to fund our education programs, advocacy work, and conservation of bird and wildlife habitats year after year. It was the most successful fundraiser we’ve ever held, raising upwards of $160,000. The best part was the fun had by the organizing committee as well as roughly 400 members of our community  who participated in the nearly 50 programs offered as part of the fundraising.

    The month of April, along with a couple of weeks before and after, was devoted to offering nearly 40 field trips led by our own volunteers and some special guest leaders. GGBA Board President Chris Tarr, and Board Treasurer Derek Heins led that effort. Chris and Derek’s familiarity with expert leaders and birding hotspots helped them put together a rich offering of trips throughout San Francisco and Alameda County as well as trips further afield. With nearly double the number of trips we’ve offered in the past, we exceeded our goal by raising $65,000. We had 278 people participate in the tours in total.

    At the tail-end of our Birdathon we hosted an Adventure Auction led by Daryl Goldman with help from Ilana DeBare, Patrick Meeker, and Mary Wand. Exciting auction items included “Bed and Bird” lodging packages, including a trip to Central Park in New York and a trip to the Rocky Mountains. Other “Bed and Bird” packages featured local options in Lodi, San Francisco, and further afield options, with three offered in Arizona and some on the north coast of California. We also had local adventure outings around the Bay Area such as a coffee tasting, a package of museum memberships, a guided history tour of Oakland by bicycle, and many others, all donated by generous members and businesses. This was GGBA’s best auction ever, raising over $23,000.

    Our Bay Birding Challenge this year featured not just two but SEVEN teams competing to see who could find the most bird species in a day as well as raise the most money. Whitney Grover, our Deputy Director, coordinated the effort. Imagine a day starting at dawn and filled with the excitement of moving from birding hotspot to hotspot until dark, trying to be the winning team.…

  • The Prelinger library

    By Chris Tarr

    An unusual field trip offered in this year’s Birdathon is a visit to the Prelinger Library. Do not miss the chance to see this amazing local hidden gem!

    I first learned about the Prelinger Library when I was in the Master Birder program with Megan Prelinger. I’m a retired librarian myself, and the first thing I marveled at was the organization of the material. The library does not follow Dewey Decimal or the Library of Congress classification system, but instead is organized in a way that suited the needs of its first users, Megan and Rick. It uses a “landscape-based, geospatial arrangement system”  starting in San Francisco and ending in outer space. It moves from landscape and nature through artiface (art, media, and culture), abstraction  (society and philosophy) to space exploration.” Here is an overview of the arrangement, or read Megan’s explanation of the arrangement here.  If you have a home library, it’s like what would happen if you had the time and space to arrange all of your materials in the way that made the most sense to you. In browsing a library collection, it’s often the materials next to the thing you are looking for that prove to be the most interesting. The arrangement itself, of course, is as revelatory as anything written with the materials contained. 

    The second amazing thing about the collection is the materials. In an SF Chronicle article written in 2015, Rick says, “We were not so interested in ordinary books that you would see at a public library. We were interested in books that were evidence in a lot of ways, books that had illustrations, books that had underrepresented or suppressed narratives in them.” “Books,” Megan says, “that expressed moments in history rather than told stories about moments in history.” Included in the library are materials they’ve used for research projects of their own,  deaccessioned library materials found on cross country collecting trips including a complete run of the Auk, a collection of New York State forestry documents which include lithographs of every lake in the Adirondacks, all kinds of ephemera. If the idea of the arrangement is serendipity, it’s the depth and uniqueness of the collection that makes that possible. Check out this Stack Explorer to see a few examples of what’s on the shelves. 

    The library was started in 2004, when Rick and Megan pooled their books and records and realized that renting a space for a library would be cheaper than renting storage space.…
