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

Friends!

Tilden Nature Area, Contra Costa, California, US
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!
