Must be a wintering bird as likely too early for a migrant.
Some years ago Townsends wintering in Oregon were assigned as breeders from the Queen Charlotte Islands, BC https://www.jstor.org/stable/1367976?seq=1 I also wonder about the current acceptance of this distribution.
A detailed discussion of ageing of Townsend's and Hermit Warblers is here https://sora.unm.edu/sites/default/files/journals/condor/v094n02/p0490-p0501.pdf If I am reading Table 2 correctly, no stage of Townsend's plumage should show yellow in the crown (Score = 8 in Table 2), but maybe I misinterpret. I find few if any such birds in the Macaulay Library, but I did not check exhaustively.
Would this make it a Hermit Warbler intergrade? There doesn't seem to be much else to indicate Hermit Warbler? Is it a transitional molt stage? Hopefully Mr. Pyle might comment? Thanks to all for any assistance.
