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:

Like a pale, giant Tawny Owl. Yellow bill, long, evenly barred, tail. Eyes dark. Facial disks pale, unmarked and almost fused, lacking the dividing wedge of Tawny Owl. In flight, note lack of pale base of primaries and much slower wing-beats than Tawny. Mild facial expression, but very aggressive at breeding ground.

Sound:

Song: 6 -10 evenly spaced "ho"'s, starting silently and gradually rising in volume and pitch. Also an accented "ho-ho, ho-ho-it, ho-ho", three middle notes ascending and the two notes before and after descending. A variety of barking social sounds.
