Probably our duck better known, both for their beauty, because if too close to urban areas and its typical corner. Is your vocalization that bears its name or Irerê paturi, very sharp and loud, remembering the sound of some whistles or the sound of rubber toys.

The white mask on the face contrasting with the black neck and lead spout makes this species unmistakable. The chest is brown and the rest of the body is finely striated in black and white. When in flight you can see the dark wings.

Like other ducks feeds basically submerged plants and grasses on the banks of the lakes, but also eats aquatic invertebrates, small fish and tadpoles.

It is most active in the twilight and night. It is not uncommon to hear the chirp of this bird flying over the night even big cities in droves. Enough to form flocks of several dozen individuals, especially during seasonal migrations that performs in the South.
