Dendrocygna bicolor wilhelma.jpg

The fulvous whistling duck (Dendrocygna bicolor) is a tropical and subtropical bird in the family of ducks, geese and swans. It breeds in much of Mexico and South America, the West Indies, the southern US, sub-Saharan Africa and the Indian subcontinent. It has mainly reddish brown plumage, long legs and a long grey bill, and shows a distinctive white band across its black tail in flight. Like other members of its ancient lineage, it has a whistling call. The preferred habitat is shallow lakes, paddy fields or other wetlands with plentiful vegetation. The nest, placed among dense vegetation or in a tree hole, typically holds around ten whitish eggs, which hatch in 24–29 days. The downy grey ducklings leave the nest within a day or so of hatching, but the parents continue to protect them until they fledge around nine weeks later. The fulvous whistling duck feeds in wetlands by day or night on seeds and other parts of plants. It has a huge range and is not threatened, despite hunting, poisoning by pesticides and natural predation by mammals, birds and reptiles. (Full article...)
