MC said "Any chance we can age this particular bird? The idea that it might be 7 years old (young?) is spectacular" It also says a lot about site fidelity for breeders and the kind of plants/habitat t

Can someone tell me where the Prairie Warbler was seen? Was it fleeting? I still haven’t seen enough of this bird in my life so it seems chase-worthy. Thanks, Bob Hall SF

Birding by bus line would be an interesting competition. Bob Hall SF

Boats: The General Public is allowed to launch personal boats that are not gas motorized in the North Lake Merced only. Does this mean you were seeing electric powered boats on the water? Bob Hall SF

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

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.
