Appearance:

Adults in summer at close range unmistakable. Bill in juveniles almost black, and much less deep than in adults. Adults in winter plumage also show much darker bill and cheeks than in summer. At a distance head gives an all dark impression, with characteristic dark "shadow " in front of the eye. Head and bill less elongated than in other auks. Wings rounded with dark undersides. "Thighs" dark. Flight fluttering and energic, with shifting weight and angle.

Sound:

Deep, but not so coarse as Razorbill. Smoother and more gliding changes in pitch, like a "slow-motion" laugh or distant chainsaw; "aaaahrrr, aahr, ahr arh".

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".
