(noun) A type of tropical duck with long, gangly legs and a long neck, as opposed to the shorter legs and necks of most duck species. Also unlike most duck species, both male and female whistling-ducks look similar rather than having drastically different plumages. True to their name, these are gregarious birds with a variety of whistling calls.
There are eight species of whistling-ducks, including wandering, fulvous, spotted and lesser whistling-ducks.
