The Anserinae are a subfamily in the waterfowl family Anatidae and includes the swan and geese. Under alternative systematical concepts (see e.g., Terres & NAS, 1991), it is split into two subfamilies. The Anserinae contains geese and ducks, while the Cygninae contains the swans.

Systematics

Swans (Tribe Cygnini) ^[1]

• Genus Cygnus – true swans: The black-and-yellow-billed swans are sometimes separated in the genus Olor.
• Genus † Afrocygnus (Miocene of North Africa)
• Genus † Annakacygna – short-winged swans (Miocene of Japan)
• Genus † Megalodytes (Miocene of California)

True geese (Tribe Anserini)

• Genus Anser – grey and white geese
• Genus Branta – black geese (including † B. rhuax , formerly placed in Geochen)

Unresolved

• Genus Coscoroba – coscoroba swan

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

• Genus Cereopsis – Cape Barren goose
• Genus † Cnemiornis – New Zealand geese (prehistoric)

Some enigmatic subfossils of very large goose-like birds from the Hawaiian Islands do not appear to be moa-nalos (goose-sized dabbling ducks) or B. rhuax. They cannot be assigned to any genus living today, though both may be fairly close to Branta:

• Very large Hawaiʻian goose, ?Branta sp. ^[2]
• Giant Oʻahu goose, Anatidae sp. et gen. indet. ^[2]
