Lesser Goldfinch?

No I don't think so, Lessers tend to be slower, less bubbly, and repeat each note a few times before moving to the next.

you live in Pennsylvania now?

I'm here for college. I'm originally from Idaho.

Sounds like a weird American Goldfinch.

Old topic, but it's still a good one.

I have 119 species for my yard currently ?.  Obviously a bunch of those are flyovers and birds that don't visit the feeders. I need to make a list of my regular visitors, but mostly it's House Sparrow, House Finch, Northern Flicker, Black-billed Magpie, Yellow-headed Blackbird, Brown-headed Cowbird, Red-winged Blackbird, Lesser and American Goldfinch, California Quail, and Dark-eyed Junco. Last winter I had a huge eruption of Evening Grosbeaks which was awesome! 

I forgot the hummers. I get Black-chinned, Broad-tailed, Calliope, Rufous, and the occasional rare Anna's.

That's a chipmunk. I learned this one the hard way after moving to Pennsylvania ?

No, Common Goldeyes have black bills that are long in thin. The bills on these birds are white with black tips.

I've never heard Common Goldeneye bills described as "long and thin" - and females have orange tips on theirs.

Maybe a duck of some sort. It is hard to tell because its bending it's head down in it's fur.

Also a coot, and the "down" on birds is still feathers, not fur.

On these birds, there is a Summer form and a  Winter form. In Summer form, these birds are black. In Winter form, they are more brown.

They should look identical.

[kingbird?]

This is a young bird by the looks of it. I agree with Western -- I would expect Cassin's to be much darker and have gray extending farther into the breast.

[Dark morph RTHA?]

This is an "intermediate" morph Red-tailed Hawk. I'm not good with the other subspecies, but I know this isn't a Harlan's. Harlan's should basically look black and white with practically no rufous tones, and the entire front and underwing coverts should be black. The tail from what I know can be red in Harlan's, but in the ones I've seen it's always been pure white.

how about 2 different species of warbler next to/on a branch

I tried to do that one but nobody could get it ?

[Connecticut or Mourning Warbler?]

I think this is a Nashville Warbler. Both Mourning and Connecticut Warblers are bulkier.

Do juvenile Nashvilles have gray throats?

Brewer’s Blackbirds don’t have contrasting white throats nor pale-based stout bills. This is a Brown-headed Cowbird.

Thanks! I thought they could both have that.

I'm not sure what this is, however I can say with certainty that it was the size of a house sparrow. That was one of the smaller brewers blackbirds that was within the flock. I'll add an uncropped photo that gives a better perspective of the size.

 

Size is really deceiving. Since the male is facing left and we can see the whole body, and the female is facing the camera and is squatted down, I'd reckon they're actually a similar size. I'm good with female Brewer's.

Just to note, none of the contrasting features of House Sparrow are visible, and scaly-breasted munias definitely don't look like this.

[Scaly Breasted Munja, Sacramento California]

That's a female Brewer's Blackbird I think. For some reason it looks really tiny next to the male. (I was also considering Brown-headed Cowbird)

[What kind of bird is this?]

Gray Catbird. Welcome to Whatbird!

[Cooper's Hawk?]

Yep!

This is 100% a celata Orange-crowned with the short bill, lack of a prominent supercilium, no faint wingbars, streaking on the breast, etc.

Ah, different subspecies. Thanks!

[Wallkill River NWR, Liberty Marsh (Part 5)]

1-2 Swallow species. Initially thought Violet-green but they're out of range. Tree?

3. Yellowleg sp.

[American Redstart vs drab Yellow Warbler?]

Why is this not a Tennessee Warbler? The contrast between the yellow rump and white undertail coverts is clear in the first photo. In addition, the overall coloration doesn't look like Orange-crowned to me. 

[Several Thrushes and 2 others]

There's a White-throated Sparrow in the first one, and all the thrushes are Hermit, except maybe the third to last.
