Chloephaga rubidiceps (Ruddy-headed Goose)

Wikipedia Abstract

The ruddy-headed goose (Chloephaga rubidiceps) is a large sheldgoose, which breeds in southernmost South America. It breeds on open grassy plains in Tierra del Fuego, Chile and the Falkland Islands. The South American birds are now very rare. They winter on lowlands in southern Argentina, some distance north of the breeding range. The Falklands population is resident. Ruddy-headed goose is a stocky 45–50 cm bird with a pale grey back, and black-barred rich buff underparts. The head and upper neck are chestnut brown. Sexes are similar, but immature birds are duller.
