The Canada Goose (Branta canadensis), a large and distinctive waterbird, is a well - known presence across North America and has spread to various parts of the world. With its characteristic black head and neck, offset by a bright white “chinstrap” that extends from cheek to throat, it's easily recognizable. This species can range from 76 to 110 centimeters in length, with a wingspan stretching from 1.3 to 1.7 meters, and males are generally larger than females. Its body is covered in brownish - gray plumage, and the underparts often display a lighter shade, sometimes creamy or white.
