It might be “Canada goose (Branta canadensis)” but could also be “Cackling goose (Branta hutchinsii)”
According to Wikipedia: “The cackling goose was originally considered the same species or a subspecies of the Canada goose, but in July 2004 the American Ornithologists’ Union’s (AOU) Committee on Classification and Nomenclature split the two into two species, making cackling goose into a full species with the scientific name Branta hutchinsii. The British Ornithologists’ Union (BOU) followed suit in June 2005”.
