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:

Differs from House Sparrow by warm brown crown, white cheeks, white (incomplete) collar and diagnostic, black cheek patch. From Spanish Sparrow by cheek patch, and lack of black breast markings. Brown and streaked rump. The black bib does not expand towards the chest. Head profile rounder and neater than House Sparrow, with slightly smaller bill. Identification by profile alone is possible with practice. Sexes and ages alike.

Sound:

Distinct, high-pitched and explosive contact-call; "che-witt" typically given in flight. Second syllable rising rapidly in pitch. Most other sounds similar to House Sparrow, and may be difficult to identify. Chattering sounds are generally harder, and song slightly higher pitched than House Sparrow.
