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.

Appearance:

Summer plumage unmistakable, with black underparts framed in white, with white and grey-speckled upperparts. Diagnostic in all plumages are the black armpits, which are clearly visible in flying birds. Also shows white wing-bars and very pale tail, with some barring. Winter-plumaged and juvenile birds speckled in grey with white underparts. Can be mistaken for Golden Plover. Especially the juveniles, which may have faint golden tone to plumage. Note instead heavier bill with swollen tip and bulkier body.

Sound:

Contact call diagnostic. A plaintive, drawn and trisyllabic (but continuous) "kleeooowee". Pitch falls on second syllable and rises on last.
