Chloephaga
''Chloephaga'' is a genus of sheldgeese in the family Anatidae. Other sheldgeese are found in the genera ''Alopochen'' and '' Neochen''. Taxonomy The genus ''Chloephaga'' was introduced in 1838 by the English naturalist Thomas Campbell Eyton in his ''A Monograph on the Anatidae, or Duck Tribe''. He designated the type species as ''Chloephaga magellanica''. This is ''Anas magellanica'' Gmelin, JF 1789, which is a synonym of ''Anas leucoptera'' Gmelin, JF 1789. ''Anas leucoptera'' is now considered as a subspecies of the upland goose ''Chloephaga picta leucoptera''. The genus name comes from the combination of the Ancient Greek ''khloē'' meaning "grass" with ''-phagos'' meaning "-eating". A molecular phylogenetic study by Mariana Bulgarella and collaborators published in 2014 found that the Orinoco goose in the monotypic genus ''Neochem'', was embedded in the genus ''Chloephaga'': Based on this result, some authorities place the Orinoco goose together with the Andean goose i ...

Upland Goose
The upland goose or Magellan goose (''Chloephaga picta'') is a sheldgoose of the shelduck-sheldgoose subfamily of the Anatidae, the biological family that includes the ducks and most duck-like waterfowl such as the geese and swans. Sheldgeese resemble true geese and display similar habits, yet they are more closely related to shelducks and ducks. The two recognized subspecies of upland goose are the continental ''picta'' subspecies and the insular (island) ''leucoptera'' subspecies. This species nests and breeds close to water (rivers, ponds, oceans) either on the ground or near it among vegetation, usually in grasslands or coastal meadows in the Falkland Islands or in southern Patagonia and Tierra del Fuego at the beginning of the austral summer. Population estimates suggest the insular subpopulations are stable, but continental populations show a recent decline in abundance. Upland geese are herbivores, specializing in plant leaves, stems and seeds. Taxonomy The upland go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
