Wooded or tree-lined streams and ponds.

Behaviour

These handsome, conspicuous birds often rest on large tree branches, stakes, or poles in the water, also on the ground, by bodies of water.

Breeding

The 12-16 white eggs are placed in a tree cavity or man-made nest box without a nest lining, occasionally on the ground among reeds.

Diet

Almost entirely herbivorous, they feed in shallow water on tubers and other aquatic vegetation, as well as in grain fields.

Unlike many ducks, this species is largely nocturnal, migrating at night and resting and feeding during the day.

Vocalisation

Squeaky whistles, often in flight.
