Appearance:

At a distance quite similar to Guillemot. Bill deep, rectangular and with white markings. Flanks unstreaked and armpits white. Tail longer than in Guillemot, with legs not protruding behind tail in flight. Tail often held clear of the surface when swimming. Cheeks white in winter, with broad, short and black eye stripe. Neck collar short and wide. Upperparts blacker, and underparts whiter than Guillemot. Heavy neck, head and bill, in combination with the long tail, gives it a front heavy, and different profile from Guillemot, whether perched, swimming or flying. Top of head in line with tip of uptilted bill when swimming.

Sound:

Very coarse and deep voice. Grunting or snore-like, with little phrasing. Mostly heard at breeding ground, but also sometimes at sea.
