Alan, As I have mentioned before, thanks for leading the group. As always a very educational experience. I posted my photos from today's walk at: http://birds.avianist.com/2017/170505-Jewel-Lake And I say the Pacific-slope Flycatcher was the star of the show.
I did have one unidentified "black bird" located in the pine
trees behind the Education Center. I had pointed it out to
several members of the group, but because of the backlit
situation, no one could help with the identification. Photos of
this birds are the last two on the site for this walk. If someone
recognizes this bird, I'd appreciate any assistance with the id. Thanks George On 5/5/2017 10:50 PM, Alan Kaplan

Friends! May 5, 2017 8:30 AM - 11:30 AM Golden Gate Audubon Society First Friday Walk, May 5, 2017. We met at the Tilden Nature Area parking lot and walked to Jewel Lake on the road and Boardwalk, with a detour on the service road to see an Anna's Hummingbird nest in a California Bay tree. FOS Swainson's Thrush for many today. Theme was syrinx and brain. See Cornell Laboratory of Ornithology's third edition of Handbook of Bird Biology for details. The non-Passerine birds who show vocal learning, the Parrots and the Hummingbirds, each have a learning system in their brains that is different from (but analogous to) the song learning system in the songbirds. Here are the 33 species seen by the MoB (many observers) of 38 birders: Mallard Wild Turkey Turkey Vulture Red-shouldered Hawk Red-tailed Hawk Anna's Hummingbird on nest Hairy Woodpecker Northern Flicker Pacific-slope Flycatcher Hutton's Vireo Warbling Vireo California Scrub-Jay Common Raven Tree Swallow Violet-green Swallow Chestnut-backed Chickadee Bushtit Red-breasted Nuthatch Pygmy Nuthatch House Wren Pacific Wren Bewick's Wren wren hat trick! Wrentit Swainson's Thrush First of Season for many observers American Robin Orange-crowned Warbler Wilson's Warbler Dark-eyed Junco Song Sparrow California Towhee Spotted Towhee Black-headed Grosbeak Purple Finch Best of Boids! |
