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 wader with yellowish legs and short, almost straight, dark bill with pale base. Noticeably smaller than Dunlin, and with shorter and straighter bill. Similar in size to Little Stint, but legs light yellowish, tail longer with white edges and markings on back quite plain. Clear divide between markings of breast and white underparts. Juveniles with prominent scale-pattern on back. Upperparts of adults in winter plumage more evenly grey, lacking the star shaped spots of summer. Prefers fresh or brackish waters, even on migration.

Sound:

Call a hard, thin, ringing "trrrrrr". Song a cyclic series of variations on the call; "trrrrrrrr" rising and falling in pitch. Often sustained for several minutes at a time.
