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.

Appearance:

Hard to distinguish from Guillemot, especially at a distance. Bill heavier, shorter, less pointed and with lateral white stripe at base (not obvious at a distance). Flanks lacks Guillemot's streaking, and armpits are white. Upperparts blacker, without brownish tones. Tail shorter than razorbill, with protruding feet in flight. Only lower cheeks white in winter, with the area behind the eye being black (white in both Guillemot and Razorbill). Pointed (not rounded) white wedge protruding from front of chest to lower throat. Neck, head and bill, heavier than in Guillemot, but more slender than Razorbill. Bill often tilted downwards in flight.

Sound:

Coarse and deep voice, like a cross between Guillemot and Razorbill. Coarser than Guillemot but with the same laughing ending, but slower.
