General Information
The White-winged Wood Duck is a species of duck usually placed in the genus Cairina and allied with the dabbling ducks. It is one of the rarest ducks in the world.

Physical Description
The White-winged Duck is a rather large bird with a dark brown, almost black, body. Its white patches on the wings are most easily seen when the birds extend them for flight. They also have a white head and neck, which has a dense amount of black spots.

Diet
The White-winged Duck feeds mostly at night, eating seeds, aquatic plants, insects, larva, worms, small fish and frogs. They spend most of the day in the shade of tall trees in order to avoid sunlight.

Habitat
As of 2002, the White-winged Duck had a population of only 800, with about 200 in Laos, Thailand, Vietnam and Cambodia, 150 on Sumatra, and 450 in India, Bangladesh and Myanmar. They live in shady rain forests, streams, and marshes; however, agricultural fields are quickly destroying their homes.

Reproduction
Females lay up to 15 greenish-yellow eggs in the hole of a tree, forked branch, or hollow trunk. The eggs are incubated for about 30 days, and will fledge after 14 weeks. The chicks are dark brown with lighter under-parts.
