Poznámky
Sterna sp. on the right; Two FOTE left. Gray breast; smaller than Forster's.
Podrobnosti k pozorování
This bird doesn't add up either to Forster's or to Common (or, ha-ha, Arctic) A tch smaller than the Forster's Terns, gray breast and belly contrasting with white throat. Slightly darker gray mantle than Forster's. Wingtips just barely as long as tail; perhaps a smidge shorter. Underside of primaries appeared dark in the last photo; I don't think this was just a shadow as I can also see the pale primary shaft. While all of those plumage characteristics fit COTE, the color (orange) and size (matching Forster's rather than Common) are a better fit for Forster's.
