Temporal range: Middle Miocene to present
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 the ducks, while the Cygninae contain the swans.
- 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
- Genus Chen – white geese (sometimes included in Anser)
- Genus Branta – black geese
- Genus Coscoroba – coscoroba swan
The following two genera are distinct from other geese and often elevated to a subfamily of their own (Cereopsinae), or alternatively into the shelduck subfamily Tadorninae:
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.
