The Canada Goose (Branta canadensis) is a goose belonging to the genus Branta native to North America. It is sometimes called Canadian Goose, although that is not considered to be strictly correct according to the American Ornithological Union and the Audubon Society.
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.
Canada Geese have reached northern Europe naturally, as has been proved by ringing recoveries. The birds are of at least the subspecies parvipes, and possibly others. Canada Geese are also found naturally on the Kamchatka Peninsula in eastern Siberia,
eastern China, and throughout Japan.
Like most geese, the Canada Goose 
is naturally migratory with the wintering range being most of the United States. The calls overhead from large groups of Canada Geese flying in V-shaped formation signal the transitions into spring and autumn. In some areas, migration routes have changed due to changes in habitat and food sources. In mild climates, such as the Pacific Northwest, due to a lack of former predators, some of the population has become non-migratory.
The diet of the Canada Goose
includes green vegetation and grains. The Canada Goose eats a variety of grasses when on land. It feeds by grasping a blade of grass with the bill, then tearing it with a jerk of the head. The Canada Goose also eats grains such as wheat, beans, rice, and corn when they are available. In the water, it feeds from silt at the bottom of the body of water. It also feeds on aquatic plants, such as seaweeds.
During the second year of their lives, Canada Geese find a mate. They are monogamous, and most couples stay together all of their lives. If one is killed, the other may find a new mate. The female lays 4–8 eggs 
and both parents protect the nest while the eggs incubate, but the female spends more time at the nest than the male. Known egg predators include Arctic Foxes, Red Foxes, large gulls, Common Raven, American Crows and bears. During this incubation period, the adults lose their flight feathers, so they cannot fly until after their eggs hatch. This stage lasts for 25–28 days.
Adult geese are often seen leading their goslings in a line, usually with one parent at the front, and the other at the back. 
While protecting their goslings, parents often violently chase away nearby creatures, from small blackbirds to other geese, to humans that approach, after warning them by giving off a hissing sound. Most of the species that prey on eggs will also take a gosling. However, geese may form groups of a number of goslings and a few adults, called crèches. The offspring enter the fledging stage any time from 6 to 9 weeks of age. They do not leave their parents until after the spring migration, when they return to their birthplace. Once they reach adulthood, Canada Geese are rarely preyed on, but can be taken by Coyotes, Red Foxes, Gray Wolves, Snowy Owls, Great Horned Owls, Golden Eagles and, most often, Bald Eagles. Canada Goose populations inhabiting areas also inhabited by domesticated geese can and will interbreed with them, producing offspring that often resemble Canada Geese in shape, but with a white or gray body, dark grey head and neck, and off-white chin, with pink feet.
