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:

Compact built bird attached to rocky habitat. Differs in all plumages from Blue Rock-thrush, Monticola solitarius by short, rufous tail and shorter bill. Primary projection very long, and wing-tips almost reaches end of tail in perching birds. Male in breeding plumage unmistakable with blue-grey head, orange-buff underparts and white patch on back (variable). Male resembles female and immature birds when not in breeding plumage, but can sometimes be sexed by partly grey head and hints of white on back. General characteristics of non-breeding plumage are greyish brown and speckled upperparts, and orange-buff, vermiculated underparts. Then told from female Blue Rock-thrush by aforementioned different build, bill and tail, and also by paler throat-sides/breast and warmer rufous flanks. Posture usually upright with giss resembling more a wheatear than a thrush.

Sound:

Alarm call a soft, wheatear-like "peeu", often accompanied by harder "tek" calls. Also a very nasal, drawn-out wheeze. Song varied and pleasing, and often very difficult to tell from Blue Rock-thrush. It is generally softer, more varied and the deeper notes are less tremulous and vibrating. A higher proportion of the song is in the higher register, with fewer lower fluting sounds, and more mimicry. Both sexes sing, but females less than males.
