The
black-bellied whistling-duck (
Dendrocygna autumnalis), formerly called the
black-bellied tree duck, is a
whistling duck that breeds from the southernmost United States and tropical
Central to south-central
South America. In the USA, it can be found year-round in peninsular
Florida, parts of southeast
Texas, and seasonally in southeast
Arizona, and
Louisiana's Gulf Coast. It is a rare breeder in such disparate locations as
Arkansas,
Georgia, Tennessee, and
South Carolina, though it is now a common breeder in parts of central Florida. There is a large population of several hundred that winter each year in Audubon Park in uptown
New Orleans, Louisiana. Since it is one of only two whistling-duck species native to
North America, it is occasionally just known as the "whistling duck" or "Mexican squealer" in the southern USA. (
