Appearance:

Very similar to Hooded Crow, apart from the all black plumage. Easily confused with young Rooks, since these lack the naked bill base and baggy trousers of adults. Carrion Crow differs from Rooks by deeper bill with a more curved upper mandible (bill of Rook conical). The wings are evenly broad, not more narrow closer to the body (difficult to judge). Carrion Crow shows no hint of crest, as is often seen in Rooks. Differs from Raven in less deep bill, no neck ruff and rounded, not wedge-shaped, tail.

Sound:

Probably impossible to tell from Hooded Crow by sound with certainty, but tends to sound harder, and more mean.

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".
