The ferruginous duck breeds between April and June, either in single pairs or loose groups. The nest usually consists of a low platform of reeds and other vegetation, built on the ground, in dense reeds, or on a floating mat of vegetation. Between 7 and 10 eggs are laid, and are incubated by the female alone for 25 to 28 days. The young ducks fledge at around 55 to 60 days, and reach sexual maturity at one year (9) (10). The species is generally migratory, with most birds leaving the breeding grounds between August and October, and returning again from early March (2) (9).
The ferruginous duck is usually found singly or in small groups, although larger groups often form on the wintering grounds or during the moult. Feeding takes place by dabbling at the surface, swimming with the head submerged, upending, or diving, and the diet consists of seeds, aquatic plants, aquatic invertebrates, small fish, and amphibians (2) (9).
