Appearance:

An all shiny black crow with diagnostic bare, pale grey base of bill, and "baggy trousers". Juveniles lacks bare bill base and are difficult to separate from Carrion Crow. Young Rooks however, has a steeper forehead and more conical bill with less curved culmen. Tail is more rounded and base of wings more narrow. Flight action includes less gliding than Carrion Crow, and individuals are more spread when a flock flies.

Sound:

Makes similar caws as Carrion Crow, but is harsher, softer, flatter with less rolling r's. Also gives a varied song of soft gurgling and rattling sounds, interwoven with calls at breeding ground.

Appearance:

Slightly more compact than Yellowhammer, with shorter wings and heavier bill. In all plumages note; olive to grey rump, greyish lesser coverts and finely streaked flanks. Male unmistakable with black throat and eye-stripe. Female and immature lacks black throat, but have more contrasting eye- and moustache-stripe than Yellowhammer.

Sound:

Song variable, but can generally be described as a Yellowhammer phrase with no ending, or an Arctic Warbler with bunting timbre. Tempo also variable, but rhythm always even. Alarm call a thin "tseeep", similar to Rock Bunting, but more drawn out.
