The Greylag Goose (also spelled Graylag in the United States), Anser anser.
The Greylag Goose (also spelled Graylag in the United States), Anser anser, is a bird with a wide range in the Old World. It is the type species of the genus Anser. It was in pre-Linnean times known as the Wild Goose ("Anser ferus"). This species is the ancestor of domesticated geese in Europe and North America. Flocks of feral birds derived from domesticated birds are widespread. The Greylag Goose is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. Within science, the greylag goose is most notable as being the bird with which the ethologist Konrad Lorenz first did his major studying into the behavioural phenomenon of imprinting. The Greylag is the largest and bulkiest of the grey geese of the genus Anser. It has a rotund, bulky body, a thick and long neck, and a large head and bill. It has pink legs and feet, and an orange or pink bill.[2] It is 74 to 91 cm (29 to 36 in) long with a wing length of to 48 cm ( to 19 in). It has a tail to cm ( to in), a bill of to centimetres ( to in) long, and a tarsus of to centimetres ( to in). It weighs to kg ( to lb), with a mean weight of around kg ( lb). The wingspan is 147 to 180 cm (58 to 71 in).[3][4][5] Males are generally larger than females, with the sexual dimorphism more pronounced in the eastern subspecies rubirostris, which is larger than the nominate subspecies on average.[2] The plumage of the Greylag Goose is greyish-brown, with a darker head and paler belly with variable black spots. Its plumage is patterned by the pale fringes of its feathers. It has a white line bordering its upper flanks. Its coverts are lightly coloured, contrasting with its darker flight feathers. Juveniles differ mostly in their lack of a black-speckled belly.[2][6] It has a loud cackling call, HOOOOOONK!, like the domestic goose.[2] read more :
