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:

Small and compact grebe. May be confused with Red-necked Grebe or Black-necked Grebe. In all plumages; short bill and flat crown. Thicker neck than Black-necked Grebe and lacks steep forehead. Dark bill with pale tip, often surprisingly visible. Summer; chestnut neck, black head and golden crests. Sexes alike, but male slightly brighter coloured. Winter; black upperparts and white underparts (differs from Little Grebe). Pure white cheeks in adults (grey in Red-necked Grebe). Juveniles may show faintly streaked cheeks, but still giving a white impression.

Sound:

Varied. Vibrating, wailing, dry and cackling sequences. A mewing, falling and far-reaching "kiaa" and various rattling sounds.
