Greater White-fronted Goose


Scientific Name: Anser Albifrons

Population Estimate:  2.6M to 3.1M

Range / Habitat: The nominate subspecies A. a. albifrons breeds in the far north of Europe and Asia, and winters further south and west in Europe. Two other restricted-range races occur in northern North America: A. a. gambeli in interior northwest Canada, and wintering on the coast of the Gulf of Mexico, slightly larger than the nominate form, and Tule Goose, A. a. elgasi, in southwest Alaska, largest and longest-billed of all, wintering in California.

Field Notes: The Greater White-fronted Goose (Anser albifrons) is a species of goose. The Greater White-fronted Goose is more closely 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.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.
