A fairly common, range-restricted duck of southern South America, the Chiloe Wigeon is most likely to be found on lakes, lagoons, slow-flowing rivers and other bodies of freshwater.  The Chiloe Wigeon is generally a sedentary species; however, the individuals that breed in the southern most portions of South America do exhibit short-range migratory patterns to central South America. Like other dabbling ducks, the Chiloe Wigeon feeds on aquatic vegetation from the surface of the water by head-dipping and upending; it also will graze from land. Despite having a small global range, the Chiloe Wigeon is not threatened and is generally common throughout its range.
