Little Egret (Egretta garzetta)
Sandwich Tern (Thalasseus sandvicensis)
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".

CCLarge tern with black bill, with yellow tip (adults). Bill all black in juveniles. Long black cap and shaggy crest. Generally leaves a much whiter impression than other terns in the region (except Roseate Tern). Adult summer: Yellow bill-tip. Tail pure white, and upperparts pale grey. Outer primaries darker than rest of wing, and contrast increases in worn plumage. Broad white trailing edge to inner wing. Underside of primaries with faint narrow dark trailing edge. Forehead white in adult winter and first winter plumage. Juveniles: scaly upperparts and dark bill. Less evenly coloured than juvenile Gull-billed Tern. First winter birds similar to juveniles, but back purer grey and bill shorter. Can be mistaken for Gull-billed Tern, but note different profile. Flight powerful with evenly narrow wings and a front-heavy appearance, due to the long head and bill. Often dives from high above the surface and stays under water longer than Common and Arctic T.
Sound:Contact call a sharp and grating "keeree-eek". Often compared to the pressing of amalgam into a tooth.
