White-winged Tern (Chlidonias leucopterus)
Garganey (Spatula querquedula)
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.

CCCC-sound:Marco Dragonetti, Licence,Link.
Small dabbling duck. Males unmistakable with broad white supercilium and high contrast between the dark mottled breast and the lighter flanks (visible at considerable distance). Female mottled in light brown colours with typical supercilium and contrasting eye-stripe. White spot at base of bill. Throat much lighter than in Teal. Both sexes with dark and fairly long bill. Head gives a square impression due to the flat crown. Speculum in flight shows narrow white edges, lacking Teal's broad front edge. Agile flight, but lacks the twists of Teals.
Sound:Male display sound a characteristic dry rattling, like the sound of running fingernails along the teeth of a comb. A bit similar to Ptarmigan. Also heard at other times than when courting. Female: like female Teal, but typically a bit deeper and shorter calls.
