Appearance:

Breeding adult easily identified by white tail/rump combined with jet black under wing coverts and silvery upper wing. Immature with brownish back contrasting with pale, silvery upper wings and pale rump. Broad white collar, and lacks dark breast patch of immature Black Tern. Adult winter most liable to confusion with other terns, but upperparts much paler than Black Tern. Contrasting dark outer primaries and secondaries to rest of wing. Often retains some black under coverts even in winter which is diagnostic if seen. Slightly more compact than Black Tern and often recalls Little gull in shape. Bill noticeably shorter and thinner than in Whiskered Tern.

Sound:

Mostly silent away from breeding ground. Most diagnostic call a dry, rolling "krrrrrr-ta-ta" where the rolling is followed by one or two accentuated syllables, or just simply "krrrrrr". Used in excitement.

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".
