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.

Appearance:

Small, but tall and elegant Tringa. Body the size of Wood Sandpiper, but stands as tall as Greenshank. Tibia especially long. The needle-like, straight bill adds to the elegance. Pale face, especially at base of bill. Back grey in adults, with star-shaped speckles in summer and narrow, pale fringes in winter. Immatures with broader fringes and overall darker upperparts. In flight the long legs trails far behind the tail, and the narrow white wedge on the back is conspicuous. Wings are dark with no bars, and shows as the darkest part of the bird also when on ground (especially in adults). Surprisingly quick and easy take-off. Posture generally erect and tall, particularly when nervous.

Sound:

Song a slow, melancholic whistle "tu-lee-uu", with the middle part highest in pitch (and with falling glissando). Similar to Spotted Redshank in structure, but with a clear tone (little risk of confusion). Flight call/contact call similar to singular instances of alarm call of Redshank, consisting of a single note rising abruptly in pitch in a split second and then falling; "kieew". Lingers a bit at the ending of the note, giving it a clearer glissando than in Redshank.
