Finally a fall warbler to look at. Surely there must be more photos out there, not
implying that your valued photo is exactly "out there". I'm thinking Tennessee
warbler because of the sharp narrow bill, rich olive back, lack of wing bars
and light eye brow that extends distally. The eye line is a little weak but it may
be immature. I've attached a few shots of what I concluded was an immature
Tennessee warbler. The eye brow is quite pronounced but I can't think of any
other warbler with such a prominent brow except for Palm and female BT Blue.

Thanks for the feedback and supporting photos. This is my first time seeing this species so I was a little unsure, and with the fall plumages and juv's moving through a bit tricky to make a 100% ID for me.

Could it be an Orange Crowned?

Good conjecture. I thought or Orange-crowned warbler (fall version) as well, but
the back of the bird in the photo is profoundly olive and OCW tend to show more
of a grayish cast at this time of year. Nonetheless, I could not completely rule out
OCW but I wouldn't put any money on it. OCW supra-occular arch is variable from
barely there to quite pronounced.

Tennessee will always show white under-tail coverts, while OCWA always has yellow. Thankfully the photo does show a distinctly white edge to the UTC.

Well that's definitive then.
Thanks for the tip.
Now if I could only get see either species in the field.

Never underestimate the importance of a bird's butt!   :lol:

Yes Sir!
I will certainly direct more of my attention to the posterior aspect of all
birds and perhaps extend my butt scrutiny even beyond that. There's
always something to see both coming and going.

Well said Kris, your reasoning is spot on.
