Appearance:

Small and dark grebe, with squarish head and thin, uptilted bill. Adult breeding plumage distinct, with unique combination of black head and neck, and a spray of golden, fan-like feathers from eye to nape. Winter plumage birds are easily confused with Slavonian Grebe, but note dark, rear cheek-patch, and darker collar. Head profile distinct, with its steep forehead. In winter plumage highest point is above the eye, as opposed to nape in Slavonian. Much more contrasting plumage than Little Grebe. Avoids to take wing if possible.

Sound:

Territorial song a disyllabic, flute-like "zoeeee-chk". First part drawn, ascending and plaintive, second part descending and clipping. Timbre is unpure. Other calls include chittering and trilling calls resembling Slavonian or Little Grebe.

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.
