I saw this flicker in my backyard (1946 Grove St.) a month ago and it's here again today. It has yellow under the wings and tail but has a tan face with a Buffy-gray neck. No mustache or red on the na

The golden eagle was also sighted by my restoration team on Sunset Blvd before I arrived. I was like, really? Are you sure. They will be excited to hear others saw it. Bob Hall SF

No Philly vireo or green-tailed towhee. Had a black-throated grey warbler and a yellow in the albizzia at the Harding Park entrance. And a black-throated grey warbler in the concrete bridge willows. A

Birded Lake Merced from 9:30-12:30 and struck out on the goodies. Swarms of yellow-rumps in early on. There was a Bewick's wren in the brush pile near the willow trail. Cool to see eared grebes back o

After seeing black-throated grey, Nashville w.and yellow warbler at home, I skipped some chores on the hunch that a pulse of migrants was flowing through. I did a bike loop that included GGP Oak woodl

I've already had Nashville, yellow and black-throated gray in my backyard. Could be a good day to skip out on chores.

Nothing rare for the round-up. Wooden bridge area: 2 yellow warblers 1 black-throated gray 1 Bewick's wren Penguin statue and willow trail: 18 yellow warbers 1 Wilson's warbler 1 orange-crowned warble

Is the juvie sharpie a nearby (Marin) disperser kicked out of a territory by parents or has migration commenced? Or both?

Had one still singing at Mountain Lake today. Seems late and interesting. Nothing rare but lots of bird and butterfly action (and tranquility) at Sutro Rotary Meadows today. May be a good escape hatch

I’m interested in hearing what they Lawerence’s are using for habitat. It it the same set of exotic plants that have been there for years? Is it the result of some restoration work? Can anyone Identif

I was glad to hear the repeated signing of the bird. Also still singing up there was an orange-crowned warbler. Is it getting late for it to still be singing in the city? I thought they were uncommon

There was a spotted towhee singing in the meadow along with several Wilson's warblers and a pari of singing orange crowned warblers. No sign of the olive-sided flycatcher from last year.

Both are great developments! I’ll bear with the momentary scrambled data, haha. Thanks! Bob Hall

Joachim: Can you add a little about what folks may be confusing the bank swallow with? Is it because other juvenile swallows may resemble bank swallows? Thanks, Bob Hall

This is a remarkable document. I hope someone has the energy to keep it up to date. I also hope that Audubon, some day, will have a breeding bird roundup. With the rapid decline in biodiversity, it wo

A yellow warbler landed in my neighbor's acacia for about 20 seconds then flew north toward USF. 1946 Grove St.

I was at Hummingbird Farms community garden near Geneva and Moscow Friday and Sunday. The same birds were present both days. A Say's phoebe and an American Kestrel. The Kestrel was on the wires above

I should add more context before I look in the book and become biased about my observation. —Looking from the top down, greenish-yellow appearance —Lighter yellowish wash on the breast, light streakin

I’ve only seen two pine warblers in my life and I’ve had trouble with them, so that’s a possibility. When I saw the cross-hatching on the back I went to blackpoll. I look forward to further insights.

I was passing by Alvord Lake with no bins, but the place was jumping and stopped me. Four townsends nearly collided with my chest during bug sorties. I saw a suspicious bird but couldn't nail it down.
