The ashy-headed goose (Chloephaga poliocephala ) is a large sheldgoose, which breeds in mountainous areas of southernmost South America and winters on lowlands just north of its breeding range.
The lined nest is built in tall grass, and 4–6 eggs are laid. This terrestrial species favours damp upland forest clearings and feeds by grazing; it rarely swims.
The ashy-headed goose is a stocky 50–55 cm (20–22 in) bird with a pale brown back, chestnut neck and black-barred white flanks. The head is grey and paler over the crown. The inside of the legs are black and the outside of the legs are red. Sexes are similar, except that the male may have reduced or no underparts barring. Immature birds are duller and have brown heads.
In flight, this species shows black primaries, with the rest of the wing white except for a broad green bar. The male's call is a soft whistle, and the female's is a harsh cackle.
