Secret Jewel along Tomales Bay
By Ilana DeBare Bay Area birdwatchers have long flocked to Audubon Canyon Ranch’s flagship Martin Griffin preserve along Bolinas Lagoon, which for years hosted dozens of egret nests. But almost no local birders have set foot on another ACR property—its dramatic Toms Point preserve on the northern edge of Tomales Bay. Toms Point is a 70-acre
Creation of a felted Osprey chick
By Hilary Powers Bid high for the baby Osprey in the Birdathon auction – you may never see another! When Golden Gate Audubon Society called for donations of services or experiences (not stuff) to fit this year’s theme, I had to stop and think, because stuff is what I do: true-life replicas of creatures natural
Accessible birding for every body
By Chris Okon When I started birding in 2005, I went on each and every Golden Gate Audubon Society bird walk that I could: the rolling terrain of Sibley Volcanic Regional Preserve, the meadows of Yosemite, the wild hills of the Sierras, the special patches in Golden Gate Park, any opportunity to see and learn
Egret nests in Alameda, 2020
Editor’s Note: It’s nesting season! Photographer Gerry Traucht has been following a nesting colony of Great and Snowy Egrets in Alameda for eight years, through the removal of their dying nest tree in 2018 and their shift to new trees in 2019.

Sharing birds with tomorrow’s outdoor educators
By Analicia Hawkins and Aryn Maitland Throughout the past year, opportunities to connect with the birding community in person and enjoy nature together have been few and far between.

Butterflies on Mount Sutro in 2020
Editor’s Note: Liam O’Brien started conducting twice-monthly butterfly surveys on Mount Sutro in 2020 as part of our wildlife monitoring for U.C.S.F.’s new Vegetation Management Plan, which was the subject of our previous blog post. By Liam O’Brien Saturday, February 13, 2021 was a glorious day. The sun was perfect, the Castro was full of
Birds and Mount Sutro’s changing forest
By Whitney Grover “Trees, trees, beautiful trees,” the high-pitched song of the Brown Creeper rings out from a nearby tree trunk. These well-camouflaged little birds creep up the trees, hunting insects in the bark. Brown Creepers don’t breed on San Francisco’s Mount Sutro but they often come around to forage in the spring and fall.
Top Guns of Bay Area Birding, 2020
By Michael Stevens Quite a story unfolded on the eBird Top 100 lists for 2020. After many years with the same excellent birders at the top of the heap, newcomers emerged as Champion Birder of the Year in both San Francisco and Alameda Counties. It seemed remarkable because of the combination it takes to get
Osprey Cam launches fifth nesting season
By Craig Griffeath A little over seventy-five years ago, a visitor to the naval shipyards at Richmond’s Point Potrero would have encountered an impressive bustle of activity, with thousands of tough, dedicated “Rosie the Riveters” putting in long days on the heavy equipment at the yard in order to provide for their families. Today, at

Wintering Shorebirds on San Francisco Bay
By Maureen Lahiff Spring is almost here, but there’s still time to enjoy the shorebirds that are here for winter R&R. Many of the species that winter in large numbers on San Francisco Bay have come a long way on their fall migration. They spend the summer nesting in a wide diversity of habitats,
Reflecting On An Unusual SF Christmas Bird Count
By David Assmann The 2020 San Francisco Christmas Bird Count nearly didn’t happen due to the pandemic. Fortunately, San Francisco birders adapted to the challenge. Although we had to follow strict new guidelines, this winter’s count turned out to be one of the best in decades. 103 socially distanced counters ended up tallying more
