Sexes alike, but the diagnostics less developed in female. Adult: A tailless aquatic bird charracterised by slender white neck and straight pointed bill, two upstanding, backwardly directed ear tufts above head and a frill of chestnut-and-black elongated fearthers below the head. In winter (non-breeding) these 'ear tufts' much reduced, and in young birds absent. However, it has the black forehead, crown and crest, a blackish line from gape to eye, white lores and sides of the head, chin and throat, dark nape and back, mottled brown and rufous flanks and white underparts.

Nest- a conspicuous mass of water weeds c. 45 to 60 cm. in diameter with a depression in the middle, on floating mounds of grass and rubbish 20 to 100 meters from the bank, loosely anchored to growing weeds. Eggs- 3 to 5, very pale sea-green with an overlay of chalky white calcium deposit, usually becoming stained brown by contact with the soggy nest.
