Black-necked Grebe is a small grebe, similar in size to Slavonian Grebe but head rounder and bill thinner and uptilted. Decidedly less maritime than Slavonian in winter, frequenting large reservoirs and gravel pits, usually within easy reach of the coast.
Winter plumage is dark cap with pale area extending to hind crown; neck smudgy grey. Black-necked Grebe has, in summer, head, neck and breast black broken only by a golden fan of plumes extending from eye. Back black; flanks rust-red.
