Oystercatcher (Haematopus ostralegus)
White-winged Tern (Chlidonias leucopterus)
Unmistakable shorebird. Large wader with black and white plumage, striking orange-red, straight bill and red orbital ring. Legs pinkish in adults and grey in juveniles. Broad white wing-bars. Stocky build, with fairly short legs and broad chest. Flight pattern straight and level. Winter plumage with white half-collar on chin. Juveniles with browner tone to upperparts than adults, and black tip of bill.
Sound:Very vocal. Sharp, loud and far carrying, disyllabic or monosyllabic calls "ku-eek" or "kleek". Often works itself up into a crescendos of fast, piping calls, and then mellows out.

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.
