Red-crested Pochard (Netta rufina)
White-winged Tern (Chlidonias leucopterus)
Big and plump-bodied diving duck with long neck, rounded head and long bill. Male unmistakable with it's red head, long deep-red bill, distinct white flank-patches and black belly. The contrasting light grey cheeks of the female recalls female Common Scooter, but note round head, pale body and much longer neck and bill. Both sexes with very broad and striking white wingbar clearly visible in flight.
Sound:Female: Indistinct "ahrrrr -ahrrrr -ahrrrr" similar to other female diving ducks. Male: a nasal dry "qweeeek" similar in timbre to Goldeneye male, but mostly monosyllabic and with an almost barking quality.

CCBreeding 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.
