Appearance:

Summer plumage: Warm, rufous brown below like Knot, but much smaller. Bill curved and much longer, and appearance more long-legged. Winter and juvenile plumage grey above and pale below. Differs from Dunlin in slightly longer legs and bill, more pronounced supercilium, no black patches on belly (some rufous summer feathers may show when moulting) and more upright stance. Juveniles with buff-pinkish tone to breast, and scaly upperparts. Always distinct in all plumages when flying, due to bright white and crescent-shaped rump-patch.

Sound:

Flight call a soft, ringing and rolling "krrrrrt, with variations. Lacks the hoarse, nasal quality of similar call by Dunlin.

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.
