Inhabits high mountain areas of the south and central Asia – swamps, river banks and crop fields above 4,000 meters above the sea level. Its organism has adapted to harsh conditions, like very strong winds and low pressure. It spends most of the time feeding on grasses, water flora and aquatic invertebrates. Breeding takes place in pairs or in small colonies with one male and several females. After eggs are laid, ducks defend their nests together. It happens that they lay eggs to nests of other birds to increase the chance of hatching.
This species is famous for its migrations, during which ducks fly over the Himalayas, exceeding the altitude of 8,500 meters above sea level. Thus, it is considered to be the highest-flying bird on Earth.
