These birds feed mainly by diving, but they will dabble.
They eat molluscs, aquatic insects and some plants and sometimes
feed at night.
The adult male is all black except for white
flanks and a blue-grey bill.It has an obvious head tuft that gives the
species its name. The adult female is brown with paler flanks, and is
more easily confused with other diving ducks.
