Least Concern

A large waterfowl species measuring 56–76 cm in length with a wingspan of 116–145 cm. Males are larger, with a prominent black knob at the base of the bill, glossy black-and-white plumage, and iridescent sheen on wings; females are smaller and plainer.

Resident across sub-Saharan Africa, South and Southeast Asia, including India, Sri Lanka, Myanmar, and Thailand.

Generally non-migratory, but some populations undertake local dispersal in response to seasonal water availability.

Breeds primarily during the wet season, which varies regionally. Nests are ground scrapes near water lined with vegetation, and clutch size is typically 6–12 eggs.

Prefers freshwater wetlands, marshes, lakes, and ponds with abundant emergent vegetation for cover.

Found in freshwater lakes, reservoirs, rivers, and large wetlands, often in open water areas with nearby vegetation for nesting. Occasionally forages in paddy fields and flooded grasslands.

Omnivorous, feeding on aquatic plants, seeds, grains, and small invertebrates. Dabbling or grazing in shallow water and along edges.
