Orinoco geese are 61 to 76 cm (24 to 30 in) long and are resident breeders in the forests of tropical South America. Its preference is forest lakes or marshes with access to open woodland or savanna.
It has a pale head and neck, chestnut flanks and mantle and blackish wings with a white speculum. The legs are red and the bill is black and pinkish. The sexes of this striking species are identical in plumage, though the males are larger; juveniles have duller plumage than adults.
This is a largely terrestrial species, which will also perch readily in trees. It rarely swims or flies unless hard pressed. In flight it looks heavy, more like a goose than a duck, hence the English name.
The Orinoco goose is a very territorial species in the breeding season, and usually nests in hollow trees, only occasionally on the ground. The male has a high pitched whistling call, and the female cackles like the related Egyptian goose.
