The Fulvous Whistling Duck, or Fulvous Tree Duck (Dendrocygna bicolor), is a medium-sized, long-legged member of the waterfowl family Anatidae. It is characterized by its rich buff head, neck, and breast, with a darker back and mantle. The species exhibits a striking white band across its black tail when in flight, and possesses a long grey bill and grey legs.
Adults measure between 45–53 cm in length, with a wingspan of 85 to 93 cm. Males weigh between 748–1,050 g, while females are slightly lighter. The plumage is mainly reddish-brown, with a dark stripe running down the back of the neck. In flight, the lack of white markings on the wings and the white crescent on the rump are distinctive. The call is a clear whistling kee-wee-ooo, often heard at night.
The Fulvous Whistling Duck favors wetlands with abundant vegetation, such as shallow lakes and paddy fields. It avoids wooded areas and is typically found in lowland marshes and swamps.
This species has a vast range, breeding across tropical regions in Mexico, South America, the West Indies, the southern United States, sub-Saharan Africa, and the Indian subcontinent. It is known for seasonal movements in response to water and food availability.
