Appearance:

A small wader with yellowish legs and short, almost straight, dark bill with pale base. Noticeably smaller than Dunlin, and with shorter and straighter bill. Similar in size to Little Stint, but legs light yellowish, tail longer with white edges and markings on back quite plain. Clear divide between markings of breast and white underparts. Juveniles with prominent scale-pattern on back. Upperparts of adults in winter plumage more evenly grey, lacking the star shaped spots of summer. Prefers fresh or brackish waters, even on migration.

Sound:

Call a hard, thin, ringing "trrrrrr". Song a cyclic series of variations on the call; "trrrrrrrr" rising and falling in pitch. Often sustained for several minutes at a time.

Appearance:

Large tern with black bill, with yellow tip (adults). Bill all black in juveniles. Long black cap and shaggy crest. Generally leaves a much whiter impression than other terns in the region (except Roseate Tern). Adult summer: Yellow bill-tip. Tail pure white, and upperparts pale grey. Outer primaries darker than rest of wing, and contrast increases in worn plumage. Broad white trailing edge to inner wing. Underside of primaries with faint narrow dark trailing edge. Forehead white in adult winter and first winter plumage. Juveniles: scaly upperparts and dark bill. Less evenly coloured than juvenile Gull-billed Tern. First winter birds similar to juveniles, but back purer grey and bill shorter. Can be mistaken for Gull-billed Tern, but note different profile. Flight powerful with evenly narrow wings and a front-heavy appearance, due to the long head and bill. Often dives from high above the surface and stays under water longer than Common and Arctic T.

Sound:

Contact call a sharp and grating "keeree-eek". Often compared to the pressing of amalgam into a tooth.
