Caspian Tern (Hydroprogne caspia)
Little Egret (Egretta garzetta)
Very large tern, with deep, dagger-like, blood-red bill with dark tip. Large, black cap reaching well below the eyes. Grey upperparts and white underparts. Rather short tail. Outer primaries distinctly darker than the rest of upperwing, and outer underwing almost black. Unmistakable from the size alone, and leaves a gull-like impression, lacking the elegance of smaller terns. Immatures with paler bill and white forehead (as in adult winter), and markedly speckled back. Hovers and dives. Often rests on the surface, feeding like a gull.
Sound:Easily recognized by its very harsh calls. Sometimes likened to the sound of a plate of steel being dragged across a concrete floor. Similar in harshness to Grey Heron, but more drawn, with an accented middle; "Kraaeeet", or with a double syllable start "ka-ha-kraaaeet". Immature birds begs with a penetrating, sharp whistle.

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".
