White-winged Tern (Chlidonias leucopterus)
Little Egret (Egretta garzetta)
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.

Differs from other white herons in the region by dark legs with contrasting yellow feet and toes. Bill always dark, and lores grey or reddish (breeding birds). Slender and elegant build, as opposed to Cattle Egret. Only roughly half the size of Great White Egret. In flight, note much quicker wing-beats of Little Egret and that the wings of Great White seems to be positioned more at the front of the body. Skulking, foraging behaviour with less erect posture than Great White, also when moving about. Legs less protruding beyond tail in flight than in GWE.
Sound:Sometimes utters a dry, rasping "kerrr" when flushed, but is mostly silent away from breeding ground. In colonies a peculiar gurgling and vibrating sound is heard; "ghala-la-la-la".
