anserinae

The Anserinae is a subfamily in the waterfowl family Anatidae.

Anatidae is traditionally divided into subfamilies Anatinae and Anserinae.

They are in the subfamily Anserinae, in the family Anatidae, which also includes geese and ducks.

It belongs to the subfamily Anserinae in the family of ducks, swans, and geese, Anatidae.

Swans are grouped with the closely related geese in the subfamily Anserinae where they form the tribe Cygnini.

Subfamily Anserinae: Swans and geese.

Cereopsis, Cape Barren Goose - Anserinae, Tadorninae, or own subfamily?

The black geese of the genus Branta are waterfowl belonging to the true geese and swans subfamily Anserinae.

They belong to separate ancient lineages that may ally either to the Tadorninae, Anserinae, or closer to the dabbling ducks (Anatinae).

The New Zealand geese formed the extinct genus Cnemiornis of the family Anatidae, subfamily Anserinae.

In other taxonomic schemes, they are either considered a separate family Dendrocygnidae, or a tribe Dendrocygnini in the goose subfamily Anserinae.

The white geese are a small group of waterfowl which are united in the genus or subgenus Chen, in the true geese and swan subfamily Anserinae.

Subfamily: Tadorninae - shelducks and sheldgeese (This group of larger, often semi-terrestrial waterfowl can be seen as intermediate between Anserinae and Anatinae.

In 1997, Bradley C. Livezey proposed that Dendrocygna were a separate lineage from Anserinae, placing it and its tribe in its own subfamily, Dendrocygninae.

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.

Studies of the mitochnodrial DNA suggest the existence of four branches - Anatinae, Anserinae, Anseranatidae and Somaterini - with Dendrocygninae being a subfamily within the family Anatidae.

Subfamily: Stictonettinae (one genus in Australia, formerly included in the Oxyurinae, but with anatomy suggesting a distinct ancient lineage perhaps closest to the Anserinae, especially the Cape Barren Goose)

Under a traditional classification proposed by ornithologist Jean Théodore Delacour based on morphological and behavioral traits, whistling ducks belong to the tribe Dendrocygnini under the family family Anatidae and subfamily Anserinae.

Two genera of "geese" are only tentatively placed in the Anserinae; they may belong to the shelducks or form a subfamily on their own: Cereopsis, the Cape Barren Goose, and Cnemiornis, the prehistoric New Zealand Goose.

Alternatively, the Anatidae may be considered to consist of 3 subfamilies (ducks, geese, and swans, essentially) which contain the groups as presented here as tribes, with the swans separated as subfamily Cygninae, the goose subfamily Anserinae also containing the whistling ducks, and the Anatinae containing all other clades.

It was compared to that of Anserinae and Dendrocygninae (other Anseriformes were either similar to these or too unlike P. mioceanus), as well as with Pelecanidae, Phaetontidae and Phalacrocoraciformes of the "higher waterbird" radiation, and found to resemble the former in one, the latter in 4 out of 5 traits.
