Anser – Grey & white geese
The ancestors of almost all the modern domestic geese
Anser is an Old World genus considered the progenitor of most domestic geese. It contains the largest goose species among all geese.
These geese frequent wet locations with open country, adjacent meadows, or fringe vegetation.
Species in this genus may be found in marshes and agricultural regions in open countries during the winter, as well as lakes and lagoons.
These geese are primarily vegetarians, eating grass, leaves, roots, stems, fruits, and sprouts from various plant species. It also eats grain and veggies in the winter.
They graze on the ground or in the water, where they “upend” like ducks.
