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:

Only small wader in the region with a dark or spotted belly. Most common small wader in area, and an important reference species when identifying congeners. Bill quite long with slightly curved tip. Legs dark. Summer plumage with unmistakable large black patch on belly, and variable warm, rufous brown back. Juveniles and moulting adults usually shows at least some diagnostic dark spots on belly in contrast to white flanks. White V-shaped markings on back, but not as striking as in juvenile Little Stint. Only adults in winter plumage shows completely white underparts (and uniformly grey back).

Sound:

Contact call a diagnostic, very nasal "trrreeet" . Given throughout the year and in many situations, including when being flushed. Song: A drawn out, nasal "tweeet", and ringing variations on the contact call in decrescendo. Low chattering heard from feeding birds.
