Pintail (Anas acuta)
White-winged Tern (Chlidonias leucopterus)
Large dabbling duck. In all plumages distinguished from other dabbling ducks by its slim neck and elegancy. Male with dark brown head, white breast and lower neck, with white wedges extending upwards on side of neck. Long, pin-like tail. Female mostly brown, wattled plumage, with longer tail than other dabbling duck females. Both sexes with bluish bill. Speculum dark green with broad white rear edge. Front edge buff in males. Edges more prominent in flight than the actual speculum. Flight pattern closer to Wigeon than Mallard.
Sound:Female: similar to Mallards coarse laughing sound, but with a more emphasized first "haaa", and a more silent accelerating subsequent "laugh". Male: Pleasant, resonant "plop" similar to Teal, but lower pitched, richer, mellower and not so metallic. Accompanied by a higher pitched, slightly raspy whistling "aiiooo" rising and falling in pitch.

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.
