Subfamily: Anserinae, swans and geese (3–7 extant genera with 25–30 living species, mainly cool temperate Northern Hemisphere, but also some Southern Hemisphere species, with the swans in one genus [two genera in some treatments], and the geese in three genera [two genera in some treatments].
Anser is a waterfowl genus that includes the grey geese and the white geese.It belongs to the true goose and swan subfamily of Anserinae under the family of Anatidae. [2] The genus has a Holarctic distribution, with at least one species breeding in any open, wet habitats in the subarctic and cool temperate regions of the Northern Hemisphere in summer.
Genus Anser – grey and white geese; Genus Branta – black geese; 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 ...
Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans.
The avian family Anatidae, commonly called waterfowl, comprise the ducks, geese, and swans.The International Ornithological Committee (IOC) recognizes these 174 Anatidae species distributed among 53 genera, 32 of which have only one species.
A cladistic study of the morphology of waterfowl found that the magpie goose was an early and distinctive offshoot, diverging after screamers and before all other ducks, geese and swans. [ 2 ] This family is quite old, a living fossil , having apparently diverged before the Cretaceous–Paleogene extinction event – the relative Vegavis iaai ...
