Greater white-fronted goose
The greater white-fronted goose (''Anser albifrons'') is a species of goose. The greater white-fronted goose is closely related to the smaller lesser white-fronted goose (''A. erythropus''). In Europe it has been known as simply "white-fronted goose"; in North America it is known as the greater white-fronted goose (or "greater whitefront"), and this name is also increasingly adopted internationally.〔 It is named for the patch of white feathers bordering the base of its bill. But even more distinctive are the salt-and-pepper markings on the breast of adult birds, which is why the goose is colloquially called the "specklebelly" in North America.〔
==Description==
Greater white-fronted geese are in length, have a wingspan and weigh .〔〔 They have bright orange legs and mouse-coloured upper wing-coverts. They are smaller than greylag geese. As well as being larger than the lesser white-fronted goose, the greater white-fronted goose lacks the yellow eye-ring of that species, and the white facial blaze does not extend upwards so far as in lesser.〔
The male is typical larger in size, both sexes are similar in appearance—greyish brown birds with light grey breasts dappled with dark brown to black blotches and bars. Both males and females also have a pinkish bill and orange legs and feet.〔
