This is Bird Note. A flock of gorgeous waterfowl flies above a marsh on the Texas coastline. Large and slender, they have bright pink bills and legs, chestnut necks and backs, and black underparts. Their wings flash boldly, black and white. And as they fly, they whistle. They're called black-bellied whistling ducks, and they're widespread in Central and South America. They've been easy to find in the U.S. along the western Gulf Coast and Florida, but they're also expanding northward. They've been spotted nesting as far north as Wisconsin. The black-bellied's one of eight species of whistling ducks worldwide, in the tropics and subtropics. Whistling ducks are anything but typical ducks, to which they only distantly related Black whistling ducks are monogamous and the male and female look alike At roost during the day whistling ducks will sometimes stand on tree branches their long pink legs catching the sun. Late in the day, large flocks gather, then whistle their way overhead at sunset to nighttime feeding areas in fields or along the shore. A lovely and vibrant spectacle with unique sound effects.
