Canada Goose
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Anseriformes, Family: Anatidae, Genus: Branta, Species: Branta canadensis
Family: Anatidae (Ducks, Geese, and Swans)
- Shape
- Highly asymmetrical vane, typical of flight-enabling feathers; the leading edge (outer vane) is much narrower than the trailing edge (inner vane). The tip is rounded and slightly tapered.
- Size
- Estimated at 8–10 inches (20–25 cm) in length. This is consistent with the primary flight feathers of a large-bodied waterfowl species like a Canada Goose.
- Rarity
- Very Common; one of the most widespread and easily recognized birds in North America.

Description
This feather belongs to the Canada Goose, a large waterfowl with a distinctive black head and neck, white 'chinstrap,' and brownish-grey body. They are known for their 'honking' calls and V-formation flight patterns during migration.
Colour & Pattern
Solid charcoal grey to brownish-black on the upper surface of the vane, fading slightly toward the base. No banding or spotting is present. The underside is a lighter silvery-grey.
Barb Structure
Pennaceous; tightly interlocked barbs creating a stiff, aerodynamic surface. The base shows plumulaceous (downy) barbs for insulation. Barbules are strong with well-developed hooklets for wind resistance.
Texture & Surface
Smooth, stiff, and slightly oily to the touch. The surface has a matte to semi-glossy finish, characteristic of water-repellent waterfowl plumage.
Key Features
Large size, extreme asymmetry of the vane, solid dark grey/brown coloration without patterns, and a very thick, rigid rachis.
Habitat
Found in a wide variety of habitats including lakes, ponds, bays, marshes, grain fields, and urban parks with open grass near water.
Geographic Range
Native to North America; breeds across Canada and the northern US, migrating to the southern US and Mexico, though many urban populations are now year-round residents.
Ecological Role
Primary herbivore; they graze on grasses and grains, dispersing seeds and providing a food source for large predators like coyotes and eagles. Their presence can significantly impact local water quality.
Similar Species
Tundra Swan feathers (larger, pure white) or Greater White-fronted Goose feathers (smaller, similar color but different texture). Crows/Ravens have smaller, glossier feathers with different rachis curvature.
Interesting Facts
Canada Geese often mate for life and are highly protective of their nests and goslings. They can fly up to 1,500 miles in a single day during migration if weather conditions are favorable.
Condition Notes
Good condition. There is minor fraying at the tip and along the trailing edge (inner vane), likely due to natural wear or contact with the ground after molting.
