Appearance:

Unmistakable, if not in silhouette. In poor light or at a distance, when the grey plumage is not visible, confusion with other crows is possible. Bill is deeper than in Rook, and the upper mandible more curved towards the tip. Smaller than raven, and much less heavy bill. The wings are shorter and more rounded, and the tail is not wedge-shaped. Posture less upright than Rook.

Sound:

Cawing is aggressive and more raucous than in Rook, with more rolling r's. Has a large repertoire of seldom heard calls, and even sub-song. Many of these calls are surprisingly resonant and pleasant sounding, and sometimes resembles Raven. Probably impossible to tell from Carrion Crow with certainty by sound alone.

Appearance:

A small, tubby and compact owl with long legs, yellow eyes and stern expression. Head without tufts or any sharp corners, proportionally smaller than in Tengmalm's Owl, and without large, white facial discs. Upperparts greyish brown to buff, with boldest white spots of any small owl in the region. Underparts whitish with heavy, brown streaking. Flight characteristic, with alternating wing flapping and closed wings. Runs, or even hops along the ground. Posture mostly erect, but hunched when in alarm.

Sound:

Song a clear drawn "klooit" resembling Scops Owl, but with different intonation and longer single notes. Tone rises slowly in pitch throughout the call and ends with marked raised pitch, often with a change in timbre to a coarse shriek. Rich repertoire of social sounds: E.g. a clear "klewew", and sharp short "kek kek kek".
