Roseate Tern (Sterna dougallii)
Pink-footed Goose (Anser brachyrhynchus)
Differs from Common and Arctic Tern by; noticably shorter wings, longer streamers, much paler grey upperparts, pure white underparts (faint rosy wash not very conspicuous), black bill (red base in breeding birds), dark outer primaries and no dark edge to inner primaries. Amount of red in bill increases as breeding season progresses, but also varies geographically. Wingbeats shallower and much quicker than in Common and Arctic Tern. Fishes with characteristic diagonal dives. Despite the long streamers, the birds appear short-tailed in flight, but head and bill are long and slender. The pale plumage, dark bill and giss recalls a small Sandwich Tern. Adult winter plumage with all dark bill and white forehead. Juveniles resembles juvenile Sandwich Terns, with more complete dark cap than Arctic and Common, and much more contrasting markings on back (especially to wings).
Sound:Extremely harsh calls. Like mix of Caspian and Arctic Tern. Very hard and raspy "kreeeet", harder and higher pitched than Caspian Tern, but equally harsh. Other calls include more Arctic/Common tern-like short "kek", and similar.

Pink bill and legs distinguishes it from Bean Goose. This can however be a deceiving character in poor light. Also differs from Bean Goose by pale grey,not brownish, upperparts. The darkest part of the body is the flanks (Bean Goose have equally dark flanks and back).
Sound:Similar to Bean Goose and White-fronted Goose, but more nasal and a little higher pitched than the first, and less musical and laughing than the second. Easily told from Greylag Goose by frequent nasal, high pitched "wink-wink".
