The greater white-fronted goose (Anser albifrons) is a species of goose related to the smaller lesser white-fronted goose (A. erythropus). It is named for the patch of white feathers bordering the base of its bill, in fact albifrons comes from the Latin albus 'white' and frons 'forehead'. In Europe it has been known as the 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. 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. Greater white-fronted geese are 64–81 cm (25–32 in) in length, have a 130–165 cm (51–65 in) wingspan, and weigh 1.93–3.31 kg (4 lb 4 oz – 7 lb 5 oz). 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 the lesser.
