Appearance:

Very large, mostly unmistakable bird. Grey upperparts, white underparts and yellow/yellowish bill. Keeps neck retracted when flying (as opposed to crane). May be mistaken for Purple Heron, but back of neck grey, not brown. Bill heavy and dagger-shaped. Neck thicker and less angular than in Purple Heron. Unmarked cheeks.

Sound:

Quite vocal. Most common call a short, far reaching and extremely harsh, rasping sound. At breeding ground a varied repertoire of harsh and clattering sounds.

Appearance:

Slender and elegant bird, about the same size as Grey Heron. Bill dark in breeding birds, otherwise yellow. Legs and feet dark, but tibia often with red tinge in breeding season. Long, S-shaped neck with sharp angle/bend. Erect posture, and less skulking, horizontal hunting behaviour than Little Egret. Almost twice the size of Little Egret, and wing-beats are considerably slower. Wings give the impression of being attached more upfront than in Little E. Feets protrude well beyond tail in flight.

Sound:

Silent outside breeding ground. In colonies various harsh calls like a dry, and mechanical "kerrrrrrr", and a very nasal "geet" or "ga-geet ga-geet" are heard.
