Anserinae

See text Cygninae The Anserinae are a subfamily in the waterfowl family Anatidae.

It includes the swans and the true geese.

Under alternative systematical concepts (see e.g., Terres & NAS, 1991), it is split into two subfamilies, the Anserinae contain the geese and the ducks, while the Cygninae contain the swans.

Swans (Tribe Cygnini)[1] True geese (Tribe Anserini) Unresolved These two genera are distinct from other geese and often elevated to a subfamily of their own (Cereopsinae), or alternatively into the shelduck subfamily Tadorninae: Tribe Cereopseini Some enigmatic subfossils of very large goose-like birds from the Hawaiian Islands 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:
