Appearance:

Small, secretive bird, usually only heard and not seen. Buff under tail-coverts and zigzag-patterned wings are diagnostic, and separates it from all other small rails in the region except American migrant Sora. Stocky build, with speckled underparts and short yellow bill with red spot at upper base.

Sound:

Loud and far reaching song uttered with relentless stamina for hours on end. A monosyllabic, resonant and drawn-out "huiiit". The pith rises towards the emphasized end of the call, which is repeated about once a second. Often compared to the dripping of water. Mostly heard at night, and often i duet with mate. The female answers the male with a slightly deeper and softer call, giving the impression of one bird giving a disyllabic call.

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.
