Anserinae

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.

Etymology

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 allied with Cereopsis, but this seems hardly correct for reasons of biogeography.
 * Giant Hawaiʻi Goose, ?Branta sp.
 * Giant Oʻahu Goose, Anatidae sp. et gen. indet.
