The Anserinae are 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 contain the geese and the ducks, while the Cygninae contain the swans.

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
  • Genus Chen – white geese (sometimes included in Anser)
  • Genus Branta – black geese
  • Unresolved

  • Genus Coscoroba – coscoroba swan

  • Anserinae Anserinae Geese amp Swans at University of Missouri Columbia StudyBlue

    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 Cereopsini

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

  • Anserinae Anserinae Geese amp Swans at University of Missouri Columbia StudyBlue

    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:

    Anserinae Anserinae Wikipedia
  • 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.
