Canada Goose (Wild Goose)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Anseriformes, Family: Anatidae, Genus: Branta, Species: Branta canadensis · Anatidae (Ducks, Geese, and Swans) · Flight feather, specifically a primary feather (likely P3-P6 based on asymmetry)
Species
Branta canadensis
Feather Type
Flight feather, specifically a primary feather (likely P3-P6 based on asymmetry)
Family
Anatidae (Ducks, Geese, and Swans)
Shape
Asymmetrical vane; outer vane is significantly narrower than the inner vane. The tip is rounded and slightly tapered, with a long, robust calamus.
Size
Approximately 10-12 inches (25-30 cm) in length. This is consistent with the primary feathers of a large-bodied Canada Goose.
Rarity
Very Common. One of the most widespread and easily observed large birds in the Northern Hemisphere.
Color & Pattern
Solid dark brownish-gray/sepia on the dorsal side, appearing more matte and slightly lighter silvery-gray on the ventral side. No banding or spots, characteristic of this species' utilitarian flight plumage.
Barb Structure
Dense, tightly interlocked pennaceous barbs throughout most of the vane for aerodynamic efficiency; plumulaceous (downy) barbs at the very base for insulation.
Texture & Surface
Smooth, stiff, and somewhat oily to provide water repellency. The surface has a matte finish that reflects the bird's aquatic and terrestrial lifestyle.
Description
This feather is a powerful primary from a Canada Goose, a bird known for its iconic black head and neck with a white 'chinstrap.' In life, these feathers support a bird with a wingspan of up to 6 feet and a loud, resonant 'honk' call. They are famous for their V-shaped flight formations during migration.
Key Features
Large size, solid dark brownish-gray color without markings, extreme asymmetry of the vane, and a very thick, stiff light-colored rachis.
Habitat
Extremely versatile; found in wetlands, marshes, lakes, rivers, grain fields, and frequently in urban parks, golf courses, and suburban lawns.
Geographic Range
Native to North America, breeding across Canada and the Northern US, and wintering as far south as Mexico. Now also widely established in Europe, New Zealand, and parts of Asia.
Condition Notes
Good. The vane is mostly intact though showing some minor ruffling on the trailing edge. The calamus is long and indicates a natural molt rather than a forced removal.
Interesting Facts
Canada Geese are known for their strong mate bonds, often staying together for life. Some populations are no longer migratory, remaining in urban areas year-round where food is abundant.
Ecological Role
Primarily grazers, they help cycle nutrients between water and land. They are also a significant prey species for large predators and scavengers.
