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.
In order to be considered fully domesticated, most species have undergone significant genetic, behavioural and morphological changes from their wild ancestors, while others have changed very little from their wild ancestors despite hundreds or thousands of years of potential selective breeding. A number of factors determine how quickly any ...
The grey goose genus Anser has no other member indigenous to the Indian region, nor any at all to the Ethiopian, Australian, or Neotropical regions.Ludwig Reichenbach placed the bar-headed goose in the monotypic genus Eulabeia in 1852, [2] though John Boyd's taxonomy treats both Eulabeia and the genus Chen as subgenera of Anser.
The magpie goose (Anseranas semipalmata) is the sole living representative species of the family Anseranatidae. This common waterbird is found in northern Australia and southern New Guinea. [2] As the species is prone to wandering, especially when not breeding, it is sometimes recorded outside its core range. [2]
