Appearance:

At a distance quite similar to Razorbill. Bill more slender, pointed and without white markings. Flanks streaked in black, and armpits with conspicuous black spot. Tail shorter than Razorbill. Cheeks white in winter, with thin black groove behind eye. Some individuals show white eye-ring and eye-groove in summer plumage. Differs from Brunnich's Guillemot in rounded, white wedge protruding from chest to throat, and all dark bill. Slender neck, head and bill, in combination with the short tail, gives it a different profile than Razorbill whether perched, swimming or flying.

Sound:

Very coarse and deep voice. Typically rising in pitch, then ending on a prolonged stable note with a laughing quality. Sometimes only the coarse beginning uttered like "ga-ga-ga".
