Crested Duck

Overview

The crested duck or South American crested duck (Lophonetta specularioides) is a species of duck native to South America, belonging to the monotypic genus Lophonetta. It is sometimes included in Anas, but it belongs to a South American clade that diverged early in dabbling duck evolution. There are two subspecies: L. specularioides alticola (Andean crested duck) and L. specularioides specularioides (Patagonian crested duck). The Patagonian crested duck is also called the southern crested duck and its range lies in the Falklands, Chile, and Argentina.
