I'm not sure which, Tennessee Warbler, or a Philadelphia Vireo.
CLOSED: I can't decide?
Burn, I could be wrong, but from that distance it looks like the beak is thinner than a Vireo's. I would guess (and it's just a guess) that it's a Tennessee Warbler. Resin???
I agree with nutsabout nature. It is a Tennessee Warbler and the bill is a good marking. Another difference I see is the Philadelphia Vireo has more white under the eye.
Thank you all, for the ID. It's another lifer. yayyyy!
