The greater white-fronted goose (Anser albifrons) is a species of goose in the family Anatidae. It is closely related to the smaller lesser white-fronted goose (A. erythropus). The greater white-fronted goose is migratory, breeding in northern Canada, Alaska, Greenland and Russia, and winters farther south in North America, Europe and Asia. The greater white-fronted goose has a length of 64–81 cm (25–32 in), a 130–165 cm (51–65 in) wingspan, and a mass of 1.93–3.31 kg (4 lb 4 oz – 7 lb 5 oz). 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. This greater white-fronted goose was photographed during migration in the Central Valley of the US state of California.Photograph credit: Frank Schulenburg
