Black-Bellied Whistling-Duck

Dendrocygna autumnalis

In the USA only south Texas, Florida and southeast Arizona are the only places where year-round you can expect to see this tree-nesting, dabbling duck. During summer, northeast Texas, Louisiana and the lower Mississippi valley can host these ducks while they raise families. Their whistling call is similar to the American Wigeon, and that, along with their obvious black belly, is how they earned their name.

In most duck species pair bonds last only long enough to pass genes, leaving the hen to rear the young on her own, but these ducks are more like geese and swans, in that their pair bonding lasts a long time, perhaps the live of the birds.
