Whistling ducks are a distinctive group of about eight species of brightly colored, oddly proportioned waterfowl. The Fulvous Whistling Duck is a mix of rich caramel-brown and black. It is a long-legged and long-necked creature found in warm freshwater marshes across the Americas, Africa, and Asia. These ducks are notable for their distinctive squealing sounds when taking off and their loud, shrill whistles during flight.

Here is one at Sylvan Heights Bird Park.
