The
Black-bellied Whistling-Duck is only in the very southern parts of the United States.
Its long neck, long legs, black belly, and white wing patch make it a
distinctive-looking waterfowl.
The
whistling-ducks were formerly known as tree-ducks, but only a few, such as the
Black-bellied Whistling-Duck perch or nest in trees. They look most like ducks,
but their lack of sexual dimorphism, relatively long-term pair bonds, and lack
of complex pair-forming behaviour more resembles geese and swans.
