Appearance:

Unmistakable in breeding plumage, but otherwise easily confused with other marsh terns. Breeding plumage with black head and belly, but pale underwing and grey rump. When in immature and winter plumage it differs from Common and Arctic tern by smaller size and short, moderately forked tail, and from other marsh terns by slimmer body and wings (compared to White-winged tern), and relatively long, thin bill. Both immature and adult winter show dark front edge of wing, and characteristic dark shoulder patch at wing base. Back is dark in immature birds. Grey rump in all plumages. Flight usually different from Sterna-terns, with erratic dives for no apparent reason, and "aimless" change of direction. Note that when foraging over saltwater, flight becomes more Sterna-like.

Sound:

Moderately vocal. Flight call a more or less clear "kleck, or a disyllabic "klee-ake" with accented first syllable. Sometimes slightly rolling "klirr-eke", but never as much as in White-winged Tern. Also a slightly harsher "kreek", but not as raspy as in Whiskered Tern.

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.
