Lesser Goldfinch

Both American and Lesser bill color varies. Both can have dark or pale bills. Americans have pale bills in alternate plumage, and dark in basic.

Wish I had better shots but these birds move too fast for my camera. If you notice all 3 were there at the same time and in the same tree. It's like when I see Bushtits flying with Chickadees.
Liam a question about the 1st and 2nd shots with the color of the bill.

1st shot shows a Lesser Goldfinch - green mantle and black on the cap are typical of the species. Black on the terminal end of the tail also helps rule out American, which only show black on the outer edges.
2nd shot shows an American Goldfinch female - note difference in color and patterning.
3rd shot is a Pine Siskin - bill is too skinny for House Finch and there is white on the tertials. The yellow on the wingbars is not visible on all birds, particularly females, and would be difficult to see from a shadowed shot like this.

Oh, Hema, you might be right. I am not used to seeing the Lesser Goldfinches. The coloration seems to be more consistent with the yellow under the tail and the narrow wingbars of the first bird. The second bird could be a pale adult female. (Where's Liam when I need him?)

Take a look, Jellis, and see what you think.

any possibility of it being Lesser Gold Finch at all?

Third picture is a house finch based on streaking on the chest - Lack of golden wingbar can rule out Pine Siskin. And based on location House Finch is also best fit for the third picture. The first two are as said winter American Goldfinch.

Warbler?

Hi Jellis! The first two pictures look like an American Goldfinch, Spinus tristis in nonbreeding plumage. House Finches have streaking on their bellies. The bird in the first two pictures does not. The third picture could be a House Finch but it is hard to tell.
