Canada Goose
Branta canadensis
The black head and neck with a white "chinstrap" distinguish the Canada goose from all other goose species except the cackling goose and barnacle goose. (The latter, however, has a black breast and gray rather than brownish body plumage.) Some Canada geese come with a pepper-spotted or brown neck with brown plumage, and these are assumed to be a leucistic variety. On occasion, individuals with dark cheeks, white foreheads or white necks may be seen The seven subspecies of this bird vary widely in size and plumage details but all are recognizable as Canada geese.
