This long-legged duck lives on the east and west coasts of Mexico and down along the eastern part of northern South America. Mostly non-migrant, black-bellied whistling ducks that live in the northern part of the range will move a smidge to the south for the winter.
Black-bellied ducks form pair bonds that last for many years, a trait more common in geese and swans. They nest in hollow cavities in trees and eats primarily water plants and aquatic invertebrates.
