Bay-breasted Warbler? central Maine, USA (1 Viewer)

I caught some brief looks at this bird which I first thought must be a Pine Warbler, but after checking the Warbler Guide I'm thinking it's possibly a Bay-breasted. That would be a first.

Thank you.

...just zis guy, you know?

I agree with the others on the diagnosis of Blackpoll here, but given how close the two species can be in fall, I think some explanation is required.

In the first post, you can see streaking on the breast in at least the first two images, and clean white undertail covs. (as opposed to buff) in all three, all of which is strong support for Blackpoll. And in post #2, the bird may be showing a bit of yellow on the underside of the toes (it may just be blur), which would be diagnositic for Blackpoll.
