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.

Weeding on the hill with CNPS sans Bins, I saw two broadwing hawks and two golden eagles around 1:20pm.

I was told that I likely saw a red-throated loon and not a Pacific loon. My birding skills have surely eroded due to neglect but I still arrogantly walk around without a bird guide, for some reason! B

Took a long walk yesterday to see the white duck of the crashing surf. Didn't expect to get lucky, but there was the long-tailed duck about 50 feet off the beach. Easy views, no scope necessary. Anoth

David: Is the Fort Mason planting plan available somewhere? I think the habitat will actually improve if they plan to replant with coffeeberry, toyons, silk tassel, etc. If you hear of a public meetin

I heard the unmistakable sound of a rock wren calling below the Land's End parking lot. Of course, if it was actually a seabird, the sound was mistakable. The reason for lack of certainty: I was on a

Speaking of Ocean Beach, there is a bioblitz there on 12/8. Birders will meet at 7:30am. Saturday, 12/89am-1:30pm (Early Bird group meets at 7:30am) https://www.eventbrite.com/e/ocean-beach-winter-bio

In the oak woodlands near the horseshoe pit I had a spotted towhee. Not totally uncommon but it's not everywhere. Shameless plug time. If you want to establish bird habitat in your backyard, buy some
