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:

Very similar to Thrush Nightingale. Anonymous, indistinct plumage and secretive behaviour makes it an easily overlooked bird (except when singing). Tail rufous brown, upperparts warm brown. Underparts buff and white. Throat without streaking. Tail more rufous, and contrasts less with the warm brown back, than in Thrush Nightingale. Overall a more smooth and clean appearance. Thrush-like behaviour despite the small size, with jumping gait, erect posture, raised tail and drooping wings.

Sound:

Alarm call either a thin, flycatcher-like "weeet", or a Chiff-chaff-like "piuu". Also a characteristic (but similar to Thrush Nighitingale) dry, rattling, frog-like "rrrrr". The song is the best characteristic to separate it from T. Nightingale. It consists of extremely resonant, full-bodied notes and lacks the, dry, rolling, rattling sounds of T.N. Most distinct species specific sound is the interwoven series of slightly ascending, plaintive notes (0.04 - 0.10 in recording). May mimic Thrush Nightningale!
