CLOSED: some kind of warbler?

Only shot of this one.

Yes; possibly a Yellowthroat, but hard to be sure. Keep an eye out in case it hangs around for a bit.

Hmmm may be a Yellow-butted Warbler just kidding, I really don't know...could be a Palm Warbler but that's taking a really wild guess.

I thought Yellow-throat, but it appears their butt is much whiter. I'm thinking Yellow-Butted Warbler also :)

Could be Yellow-rumped or Yellowthroat. If it hangs around, see if you can take a look at the head; a Yellowthroat would have a black mask.

Not Yellow-rumped, that has white under-tail coverts.
Palm has yellow under-tail coverts, but also has a white distal half of the tail from below, whereas this bird has the whole tail dark below.
Orange-crowned isn't anything like so yellow below
Oporornis warblers (KY, CT, Mourning) are suitably yellow below, but have a short, broad tail that doesn't fit at all here.
Wilson's is suitably yellow below, but is a very small bird; this one looks a bit too bulky. Probably my second choice after Yellowthroat.

One other thought . . . is it large enough that it could be a late-lingering female Scarlet Tanager?

Female Tanagers aren't nearly such a bright yellow color below.

I wish!..........I have never seen a Tanager here.
