Swainson's or Hermit


Recommended Posts

Presuming that the first two pix are of the same bird with the same tasty morsel, the contrastingly reddish upper-tail coverts and tail are diagnostic for Hermit, and with the BLACK lateral throat stripes also helping to rule out Swainson's. The third photo is of a bird lacking a complete eye ring and with no warm tones whatsoever in the upperparts plumage. Both features rule out Hermit and Swainson's, particularly the ruddier subspecies of both that breed in that part of the world. I see nothing in that photo that rules out Gray-cheeked.

Hey, I'm not crazy! I was thinking Bicknell's/Gray-cheeked for that bird!

The third still looks in range for Swainsons to me. Throwing out GCTH is a pretty big claim, it would be the second record ever for the Seattle-Vancouver area. 

I find that hard to fathom, as Russet-backed should be the breeding form of SWTH there, and it can easily be mistaken for Veery, it's so ruddy. I understand that the bird is in total shade, which can greatly reduce the apparent ruddiness in thrush plumage, but I find it hard to believe that it could make a Russet-backed that gray and remove any suggestion of a notably paler eye ring (see here, here, and here). Although Russet-backed typically has narrower eye rings than does Olive-backed, they still have complete eye rings, which the photo'ed bird seems to lack.

I would not want to claim a second local record of a species on the strength of this single photo, but I cannot see the beast being referable to either Hermit or Swainson's. The posture of the bird in total (including the slightly open beak) and the disarrangement of the throat feathering suggests to me that the bird is singing. It's a shame that the observer did not note the song, if it was singing, as that would have provided excellent support for the bird's identity, no matter that ID.

Hi Tony.. Can't say if it was singing... Can't recall... But thank you for very detailed approach... So many similarities and slight differences to consider, before coming to conclusion. My knowledge is not even close to do that. Appreciate you explanation!!!
