With white outer remige

The position of this bird in the phylogenetic tree is being questioned. Genetic studies suggest that it is basal (more primitive) to the swans, but that it is closely related to the Cape Barren Goose. This standing bird looks more like a goose than a swan. Its legs are longer and are placed more at the center of the body, which gives it a more straight posture. Other differences with swans are the bill and the lack of caruncle.
