Appearance:

Most likely to be confused with Black-tailed Godwit, but easily recognized in flight by plain dark wings, white wedge on back and barred tail. More difficult to identify when not flying. Generally more compact, heavier built and less upright than Black-tailed, and with clearly upcurved bill and shorter legs. Belly always unmarked. Base of bill dark in summer and pinkish in winter and in juveniles. Back with arrow-shaped streaking. Adult winter also streaked, and the pale supercilium reaches behind the eye.

Sound:

Quite vocal at breeding ground but mostly silent elsewhere. Varied repertoire of mewing and sharp sounds, some resembling Black-tailed, some almost Snipe-like. Contact call a sharp "kwee-kee-wee-kee", with alternating high and low pitch, and decreasing intensity. Display call a hard and sharp "kuwek-kuwek-kuwek-kuwek", with emphasis on second syllable.

Appearance:

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.
