Characteristics of Habitat

[ Back to top ]

Range and Population:

Branta canadensis has a large range, breeding across tundra in much of Canada, Alaska (USA), and parts of the northern USA, and wintering in southern North America, including Mexico. Introduced populations are now resident in much of the USA south of the normal breeding range, as well as in a number of western European countries. It has an estimated global Extent of Occurrence of >10,000,000 km², and has a correspondingly large global population, estimated at 1,000,000-10,000,000 individuals. Although hunting and other direct mortality takes a substantial toll, this species has increased its range and population since the 1940s1, and is thus evaluated as Least Concern.[1]
