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.

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:

Small, dark grebe with bright yellow gape, short neck and bill. Winter plumage paler than summer, with chestnut flanks, neck and cheeks, giving much less contrast between upper- and underparts than in Slavonian Grebe. Fluffy, pale stern. No crest or tufts/tippets and no white markings on wings.

Sound:

Relatively vocal compared to many other grebes. Call; sometimes a single quite clear high pitched "dydlylyyt". More often combined into longer phrases with harsher quality, oscillating like laughter and travelling up and down in pitch in agitated motion. Reminiscent of female Cuckoo.
