OBSERVATIONS:
Perhaps the most common small duck in Chile. It is found from Coquimbo to the south, but in greater abundance from the Lake District to Aysen. In Magallanes and Tierra del Fuego is immigration because during the winter it moves away to the north, returning in mid-September or October.
Sociable customs, will be seen in flocks of several units, including 20 or more, and relatively more gentle than other ducks, and can be observed more closely without being away immediately, as often it happens, for example, in Jergon large duck (Anas georgica).
Possible confusion with big duck Jergon which is larger, longer neck and head disproportionately large brown clear from the body.
