观察细节
In the field we felt the two bleached gulls in the photos and video looked small-billed and round-headed enough that they got us thinking bleached Thayer’s. After study of the photos and video and consultation with colleagues (thanks especially to Phil Pickering), we feel that the bird on the LEFT is indeed a Thayer's Gull, which would be quite late at this date. (The bird on the right is likely a GWGU, GWGUxWEGU, or GWGUxHEGU.)
