Appearance:

Large gull with deep chest, light grey back and heavy yellow bill with red spot (adult). Pinkish legs and black tipped primaries with white windows. Winter plumage with streaked head and neck. Develops grey mantle in 2.nd winter. Young birds may be difficult to distinguish from juvenile Greater- or Lesser Black-backed Gulls, and the species shows notable variation in both plumage and size. Juveniles generally shows darker head and less contrasting markings than Greater Black-back, and pale inner primaries (window), as opposed to the all black hand of young Lesser Black-backs.

Sound:

Quite vocal. A long and strong "ay-kay-kay-kay-kay" with fading strength commonly heard. A deep "ga-ga-ga" heard from anxious birds. All calls much deeper pitched than Common Gull. Difficult to distinguish from Lesser Black-backed Gull, but tone is less nasal.

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".
