Thursday Birdblogging

Just a few of the Black-bellied Whistling-Ducks that visit Ralph Pittenger's yard in southwest San Antonio daily for breakfast and supper.

A striking and gregarious duck of the Neotropics, the Black-bellied Whistling-Duck reaches the United States only in the very southern parts. Its long neck, long legs, black belly, and white wing patch make it a distinctive-looking waterfowl.
Cool Facts

* The whistling-ducks were formerly known as tree-ducks, but only a few, such as the Black-bellied Whistling-Duck actually perch or nest in trees. They look most like ducks, but their lack of sexual dimorphism, relatively long-term pair bonds, and lack of complex pair-forming behavior more resembles geese and swans.
