The Ashy-headed Goose (Chloephaga poliocephala) is a large sheldgoose, which
breeds in mountainous areas of southernmost South America and the 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 50-55cm bird with a pale brown back, chestnut
neck and black-barred white flanks. The head is grey. 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 its black primary feathers, with the rest of the wing  
being white except for a broad green bar. The male's call is a soft whistle, and the
female's is a harsh cackle.
