Canada Goose
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Anseriformes, Family: Anatidae, Genus: Branta, Species: Branta canadensis · Anatidae (Ducks, Geese, and Swans) · Flight feathers (Remiges); specifically a Primary (left) and likely a Secondary or inner Primary (right).
Species
Branta canadensis
Feather Type
Flight feathers (Remiges); specifically a Primary (left) and likely a Secondary or inner Primary (right).
Family
Anatidae (Ducks, Geese, and Swans)
Shape
Asymmetrical vanes. The left feather is elongated with a distinctively narrow leading edge (emargination). Tips are generally rounded to slightly pointed.
Size
Approximately 8-10 inches in length. This is consistent with the primary and secondary wing feathers of a large waterfowl species.
Rarity
Very Common. One of the most widespread and easily recognized birds in North America.
Color & Pattern
Uniformly dark grayish-brown to charcoal black on the dorsal surface. The ventral (under) side is a lighter, more silver-gray. There are no banding or spots, which is characteristic of this species' remiges.
Barb Structure
Tightly interlocked pennaceous barbs throughout most of the vane for aerodynamic integrity, with a small plumulaceous (downy) section at the very base (calamus).
Texture & Surface
Smooth, stiff, and somewhat oily to the touch. The surface has a slight matte-to-satiny sheen, providing excellent water resistance and durability for flight.
Description
These are large, sturdy wing feathers from a Canada Goose. The bird is a heavy-bodied waterfowl with a long black neck, a white 'cheek' patch, and a brownish-grey body. They are famous for their V-shaped flight formations and loud honking calls.
Key Features
Large size, dark charcoal/gray-brown color, distinct white rachis, and the extreme asymmetry characteristic of powerful flight feathers in waterfowl.
Habitat
Found in a wide variety of habitats including lakes, ponds, bays, marshes, fields, and very commonly in urban parks and golf courses.
Geographic Range
Native to North America; breeds across Canada and northern USA, wintering throughout most of the United States and Mexico. Introduced widely in Europe and New Zealand.
Condition Notes
Good condition. There is slight fraying at the tips and edges (mechanical wear), but the vanes are mostly intact. No obvious signs of parasite damage or fault bars.
Interesting Facts
Canada Geese are known for their strong pair bonds and will often stay with the same mate for life. They are also highly adaptable to human-altered landscapes, which has led to significant population increases in urban areas.
Ecological Role
They are primarily herbivores, grazing on grasses and aquatic plants. They serve as prey for large predators (especially as goslings) and their movements help transport nutrients across ecosystems.
Similar Species
Similar to other large geese (like the Cackling Goose, though smaller) or large gulls. However, the thickness of the rachis and the specific charcoal-brown hue are diagnostic for Branta canadensis.
