Cladus: Eukaryota Name Anserinae Vigors, 1825 References * Anserinae Report on ITIS Vernacular names The Anserinae is a subfamily in the waterfowl family Anatidae. It includes the swans and true geese. Under alternative systematical concepts (see e.g. Terres & NAS, 1991), it is split into two subfamilies, the Anserinae containing the geese (and also the whistling-ducks), while the Cygninae contain the swans. A number of other waterbirds, mainly related to the shelducks, have "goose" as part of their name; see the family page at Anatidae and the goose page for these. Systematics Swans - tribe Cygnini * Genus Cygnus - true swans The black-and-yellow-billed swans are sometimes separated in the genus Olor. True Geese - tribe Anserini * Genus Anser - grey geese Unresolved * Genus Coscoroba - Coscoroba Swan The following two genera are distinct from other geese and often elevated to a subfamily of its own (Cereopsinae), or alternatively into the shelduck subfamily Tadorninae: Tribe Cereopsini * Genus Cereopsis - Cape Barren Goose There are some enigmatic subfossils of very large goose-like birds from the Hawaiian Islands which do not appear to be moa-nalos (goose-sized dabbling ducks). They cannot be assigned to any genus living today, though most if not all may be fairly close to Branta: * Geochen rhuax - initially alied with Cereopsis, but this seems hardly correct for reasons of biogeography.
