"Cool facts"One of the most widespread species of waterfowl in the world, the Fulvous Whistling-Duck has a limited distribution in the southern United States. Its mostly seed-based diet makes it fond of rice-growing areas.
In some ways, whistling-ducks act more like swans than ducks. The male helps to take care of the offspring and a mated pair stays bonded for many years.
Pesticides applied to rice in the 1960s caused declines in Texas and Louisiana populations. Numbers have recovered and stabilized since then.
The Fulvous Whistling-Duck is a frequent nest parasite, laying eggs in other Fulvous Whistling-Duck nests, as well as the nests of other duck species. These other duck species often lay their eggs in Fulvous Whistling-Duck nests as well.
Unlike many other ducks which have elaborate courtship displays, whistling-ducks appear to have none.
Other than in agricultural habitats, the Fulvous Whistling-Duck nests only rarely in the United States. It started breeding in the United States only in the late 19th and early 20th centuries, nesting in rice fields.
