“A most strange duck” (Pizzey and Knight Field Guide).
The male has a large flap under its bill and has a loud and spectacular courtship display as it holds its tail up and goes around in circles, while noisily splashing, honking and whistling. They can dive deeply and feed mainly on water snails, beetles and yabbies. They are seldom seen on land and are usually alone in the middle of the lake.
