Dendrocygna autumnalis
The whistling duck is found exclusively on the American continent.
The two sexes are similar.
Its wings are rounded, making it look fatter than it is. Its bill and feet are red. It has a white mark on the wings and its abdomen is black.
The upper parts of the red-billed or black-bellied whistling duck are fawn brown to cinnamon brown. The undersides are lighter.
The bottom of the neck and chest are fawn brown. The abdomen and sides are black. The underparts are mottled black and white. The underside of the wings is blackish.
The head and the top of the neck are grey. The crown is dark brown. There is a dark vertical band behind the neck. The bill is reddish pink and often yellowish at the base. The eyes are dark brown, surrounded by a very vivid white ocular ring. The legs and webbed feet are bright red.
The black-bellied whistling duck lives in forested swamps or marshy forests. It requires humid areas with vegetation to feed on, and hollow trees nearby to nest in. This species is found from sea level up to 1,500 metres altitude.
The female usually lays 12 to 16 whitish eggs in the reeds or tree cavities about 3 metres from the ground. The incubation period lasts about 26 to 30 days.
