It is a very shy and territorial duck. It is usually seen in pairs or small flocks. It breeds throughout the year in different areas. Incubation is about 30 days by the mother and the fledgling period is 86 days and only the mother takes care of the young.

It feeds off of larvae and pupae usually found under rocks, aquatic animals, plant material, seeds, small fish, snails, and crabs.
