Bird-Boys

Seen at Ocean Beach County Park, Lompoc, CA. On 9/15/19, 10:24 AM. One was seen in the area recently. Seen with another birder who said it was a Lucy's Warbler.

4. Juvenile European Goldfinch.

This is a toughie, but I think you're right.

I would agree with your IDs, these are pretty late birds. Hummingbirds can stretch their necks and do it often so I don't think that's a reliable field mark.

Agree, Warblers can and will eat seed in fall and winter. It mentions this in an this article: http://www.birdsforever.com/warbler.html

Tennessee Warbler.

seconded.

This is a female/immature Wilson's warbler. Olive cheek and shorter bill eliminates hooded warbler, overall olive coloring and lack of longer, usually all dark bill eliminates yellow warbler.

I THINK they are all female cinnamon teal. Your other option would be female Green-winged teal, but I think the bill is to small.

1. not sure, but definitely a crow 2. short-billed dowitcher and something, I don't think it's a yellowlegs. 3. Dowitchers and yellowlegs, not sure greater or lesser. Rest: glossy ibis, lesser Yellowlegs and Greater Yellowlegs (4.-7. may not have Lesser.)

I think least is correct, agree with everything else.

Pretty sure they are cliff swallows, but any more pics showing the rump may help give a more positive answer.
