Appearance:

Unmistakable in most of Europe where no other nuthatch species occur. Only bird climbing head-first downwards trees. Blue-grey upperparts, white underparts and solid black eye stripe. Large head, long bill and short tail. Climbs in jerky, but nimble motion. Scandinavian birds with mostly white underparts (except for vent), continental birds with more rufous belly.

Sound:

Very varied voice. Ranging from very high pitched whistles and melodic resonant calls, to chattering and nasal mocking sounds. Song a simple series of loud notes. Characteristic warning call a hard "check" or "chwit", often in rapid series, like a pebble bouncing on hollow ice.

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.
