Description


It is a medium-sized duck, easily recognized by its strongly contrasting plumage and upright posture. The head is white with a distinctive black patch on the nape, giving the appearance of a “veil,” which is a key identifying feature. The neck and breast are chestnut, the back dark brown, and the flanks finely barred. The legs are relatively long and grayish, adapted for both swimming and walking.

Geographic distribution: It has a wide pantropical distribution, occurring throughout much of South America, sub-Saharan Africa, and parts of the Caribbean. In South America, it ranges from the northern regions south to central and northeastern Argentina, including Paraguay, Uruguay, Bolivia, and Brazil.

Habitat: It inhabits freshwater wetlands, such as lagoons, marshes, swamps, rice fields, river margins, and reservoirs. It prefers open areas with emergent vegetation and shows good tolerance of human-altered landscapes.

Feeding: Its diet is mainly herbivorous, consisting of seeds, grains, shoots, and green parts of aquatic and terrestrial plants. Small invertebrates are occasionally consumed, especially during the breeding season, providing additional protein.

Behavior: It is a highly social and vocal species, well known for its clear, whistling calls, particularly during flight or social interactions. It is often seen in large flocks and is active both during the day and at night. Unlike many ducks, it frequently forages on land.

Nesting: Nesting usually takes place in dense vegetation near water, where a simple nest made of plant material is built. The clutch generally includes 6 to 12 eggs, incubated by both parents, who also share care of the precocial chicks.

Conservation status: It is classified as Least Concern, with large and stable populations across most of its range. Nevertheless, wetland degradation may cause local declines.
