The Canada Goose is probably the most widely known of goose species in North America. Their distinctive call is a harbinger of spring and autumn for many who live under their migratory flight-path.

Canada Geese are prized by hunters as one of the choicest game fowl, but the animal's characteristic wariness, together with protective regulations, prevent serious depletion of its population.

These birds mate for life, and the young stay with their parents for several months after hatching. A gander protecting the nest makes a very formidable adversary: his wings are capable of delivering a blow of surprising force, sufficient to rout foxes and similar predators, not to mention humans.

Males are generally larger than females. Adult males range from 76 to 110 cm (30 to 43 in.) long. Their wingspan reaches 127 to 170 cm (50 to 67 in.).
