Genus Merganetta

Torrent Duck - This 43–46 cm long species is a resident breeder in the Andes of South America, nesting in small waterside caves and other sheltered spots. Like the Blue Duck, it holds territories on fast flowing mountain rivers, usually above 1500 m. It is a powerful swimmer and diver even in white water, but is reluctant to fly more than short distances. It is not particularly wary when located.
