Appearance:

An energetic, stocky and robust wader. Black legs and bill. Black wing-bend (not always visible), and broad white wing-bars framed in black. Summer plumage with rufous head and back. Winter and juvenile plumaged birds gives a much whiter impression than all congeners, with light grey upperparts and pure white underside. Juveniles with star-shaped, black markings on back. Lacks hind toe.

Sound:

Call not very diagnostic; a short and soft "pleet" or "keek".

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.
