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:

Biggest woodpecker in WP (crow size). All black with red crown (male) or nape (female). Unmistakable. Flight Nutcracker-like, "inefficient" and fluttering, almost without undulations.

Sound:

Most sounds diagnostic and very far reaching. Drumming very powerful and long (1.8 - 3 sec.) with slightly falling intensity and accelerated ending. Each beat clearly distinguishable as in Tree-toed Woodpecker, but duration much longer. Drumming:

Flight call a characteristic resonant trill "krrreekrrreekrrreekrrree". A characteristic short, sharp and plaintive "keeaaa" with descending pitch often uttered when excited. Song a quick series of "klee" calls resembling Green Woodpecker, but with a purer tone and upward infliction at end of each syllable. A few slower drawn-out introductory calls before the phrase gets going is diagnostic.
