Description and photos support identification of Hermit Warbler.

Photos seem to be diagnostic of a Hermit Warbler. An ideal submission of a Hermit Warbler would probably consider a Townsend's X Hermit hybrid, but I think we can see enough in the photos to rule that out. The mantle looks dull gray-brown (not at all green) with only minimal streaking, the flanks are essentially unstreaked, and the auricular patch is slight. Nice find and well-documented.

well documented with excellent photos

diagnostic pics and other possibilities considered well

I'm convinced that this was a female Hermit Warbler, but why weren't Darren's better photos of this bird included here, since they're referenced in the report?

Photos are good.

Very interesting bird. Had this been in the core if its home range, would have no problem calling it a young female Hermit Warbler (Setophaga occidentalis) based on the photos provided. However, given its vagrancy, the lack of black on its throat/chest (thus a young bird) this time of year, need to consider the possibility of hybrid origin, particularly with the common Townsend’s Warbler (S. townsendii).

While the observer does not give a detailed description, their discussion does help add context to the excellent photos. I do think this bird is likely a pure Hermit considering the relatively plain face without any sharp demarcation on any portion of the auricular patch, no break in the yellow eye ring, and lack of any distinct streaks on its flanks, all traits I would expect to be compromised in a Hermit X Townsend’s hybrid. However, the crown and back do show a hint of green, and the lores seem somewhat dark for this species, so there is room for other genetic influence. Conclusion, I believe this is a good Hermit Warbler, but may be swayed after reading any dissenting comments should this go to the next round of voting.
