Bay Area researchers have mapped the DNA of the Northern Spotted Owl, gaining information that could shed light on how this threatened Pacific Coast bird is interacting with non-native owls invading its habitat.

The California Academy of Sciences — in collaboration with U.C. Berkeley, U.C. San Francisco, the National Museum of Natural History in Paris, and the Howard Hughes Medical Institute…

Everyone loves Burrowing Owls… once they actually see one.

How birds handle hot weather September 2, 2017

By Bob Lewis

With our temperature climbing this week, some of us are wondering how birds deal with elevated temperatures. Remember, they’re sitting inside a feather quilt. A review of Cornell’s Handbook of Bird Biology and a bit of personal experience provide some clues.

Like mammals, birds control their core body temperature in a fairly narrow range. For birds, that range is usually 39-43 degrees …

There’s a tropicbird under my bed! August 22, 2017

Posted by GGAS in Birding, International Birding

By Eric Schroeder

This past spring I spent some time following the progress of a Brewer’s Blackbird family that built a nest on my horse trailer.  That concern was part of my larger interest in breeding birds, one cultivated by the Master Birding Program co-sponsored by Golden Gate Audubon Society that I completed last year. But this summer, when I went to the Great Barrier Reef in Australia to dive, I had…

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. …

Blackbird fly! (off of my horse trailer) July 5, 2017

Posted by GGAS in Birding

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…
