Canada Goose

This is a primary flight feather from a Canada Goose, a large waterbird known for its black head and neck with a white 'chinstrap'. The bird has a heavy body, long neck, and large webbed feet, with a wingspan reaching up to 5.5 feet. Their flight is characterized by powerful, steady wingbeats, often in a V-formation.

Solid dark brownish-black to charcoal grey on the upper surface. The underside is a lighter silvery-grey. The rachis is notably pale/white, which is a diagnostic feature for this species.

Tightly interlocked pennaceous barbs throughout most of the vane for aerodynamic integrity, becoming plumulaceous (downy) only at the very base near the calamus.

Stiff and relatively smooth. The surface has a slight matte finish with a waxy, water-repellent coating typical of waterfowl. The leading edge is extremely rigid.

Large size, extreme asymmetry, solid dark coloration, and a notably thick, pale/white rachis (central shaft).

Extremely versatile: found in lakes, ponds, bays, marshes, grain fields, and frequently in urban areas like parks and golf courses.

Native to North America, breeding from the Arctic to the southern US. It is a migratory species, though many urban populations are now year-round residents.

Primary herbivore that can significantly influence local vegetation. They serve as a food source for large predators and contribute to nutrient cycling in wetlands.

Other large dark birds like the Black Vulture have more deeply notched 'fingers' and lack the creamy-white rachis. Mute Swan feathers are larger and entirely white.

Canada Geese are famous for their V-formation flight, which reduces air resistance for the birds behind the leader. They are known to mate for life and are highly protective of their nests.

Good to Fair condition. There is visible separation of the barbs ('zipper' failure) on the trailing edge, likely due to impact or weather exposure after being molted. The calamus appears intact.
