Dendrocygna Genus

The whistling ducks. They have a worldwide distribution through the tropics and subtropics. These ducks have, as their name implies, distinctive whistling calls.

The whistling ducks have long legs and necks, and are very gregarious, flying to and from night-time roosts in large flocks. Both sexes have the same plumage and all have a hunched appearance and black underwings in flight.
