Appearance:

Summer: Black throat framed in fine white stripes at the sides, and a chequered black back. Winter: More contrast between dark and white parts than in Red-Throated Diver. Marked transition between dark neck and white front, and the dark grey crown extends below the eye. In all plumages: Heavier neck and bill than Red-Throated, and bill usually held straight. Visibly protruding chest when swimming. Head shape sometimes squarish. Usually shows big white flank patch.

Sound:

Song: a strong, very resonant, full bodied, low whistling with most syllables rising in pitch: "co clooo-eee, co clooo-eee, co clooo-eee". Also a short grunting "karr".

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.
