|Canada Geese on Douglas Lake. |
The Canada Goose (Branta canadensis) is a goose belonging to the genus Branta native to North America, where it is often, incorrectly, referred to as the Canadian Goose.
The black head and neck with white "chinstrap" distinguish the Canada Goose from all except the Barnacle Goose, but the latter has a black breast, and grey, rather than brownish, body plumage. There are seven subspecies of this bird, of varying sizes and plumage details, but all are recognizable as Canada Geese. Some of the smaller races can be hard to distinguish from the newly-separated Cackling Goose.
This species is 76-110 cm (30-43 in) long with a 127-180 cm (50-71 in) wing span. The male usually weighs 3.2–6.5 kg, (7–14 pounds), and can be very aggressive in defending territory. The female looks virtually identical but is slightly lighter at 2.5–5.5 kg (5.5–12 pounds), generally 10% smaller than its male counterpart, and has a different honk. An exceptionally large male of the race B. c. maxima, the "giant Canada goose" (which rarely exceed 8 kg/18 lb), weighed 10.9 kg (24 pounds) and had a wingspan of 2.24 m (88 inches). The life span in the wild is 10–24 years.
