Taxonomy
Behavior
- They also are distinguished by their appearance and behaviors in the field. Black-bellied whistling ducks fly slowly in shapeless formations. In flight, they show long necks, trailing legs, and broad wings, but the most distinguishing feature is the contrasting black and white between the upper and lower wings. When standing or perching, the most striking features are the bird's namesake …
Distribution
- The northern population breeds from central Texas through coastal Mexico and Central America. The southern population breeds from Panama south into Argentina. Like most of their tropical counterparts, black-bellies do not show strong migratory patterns; instead, they move relatively short distances in response to habitat availability within their breeding range.
Breeding
- Black-bellies breed during their first year of life, establishing lifelong pair bonds during their first winter. Nest initiation occurs from April through August, a period approximately one month longer than prairie nesting ducks. Black-bellies nest in tree cavities and, similar to wood ducks, also have adapted to nesting in boxes. Where tree cavities are lacking, black-bellies will nest on the ground…
Habitat
- During the nonbreeding season, black-bellies primarily use mangrove swamps and coastal lagoons to meet their food and cover requirements. However, similar to their goose cousins, black-bellies have adapted to feeding in agricultural environments, frequenting pastures and cattle feedlots as well as harvested rice, corn and sorghum fields when the op...

- They are very agile on land, standing erect and walking without the waddle so characteristic of other ducks. A tawny brown head, chest, breast and belly distinguish fulvous whistling ducks. Ivory-edged side and flank feathers form a striking border between the sides and back. In North America, the species is most common in Mexico, but also breeds in California, Florida, Louisian…
Population
- Comprehensive population surveys of whistling ducks are lacking. Most of our information comes from mid-winter surveys conducted by the U.S. Fish and Wildlife Service and occasional breeding season surveys associated with short-term research projects. Limited data suggest a relatively stable breeding population of around 20,000 fulvous whistling ducks in Louisiana and Texas. Sig…
