Canada Goose
Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Anseriformes; Family: Anatidae; Genus: Branta; Species: B. canadensis
Family: Anatidae (Ducks, Geese, and Swans)
- Shape
- Highly asymmetrical vane; elongated and tapered with a slightly rounded to pointed tip. The leading edge (vane) is significantly narrower than the trailing edge, typical of flight feathers designed for aerodynamic lift.
- Size
- Estimated 8 to 11 inches (20-28 cm) in length. This size is consistent with the primary wing feathers of a large-bodied Canada Goose.
- Rarity
- Very Common. One of the most widespread and easily observed large birds in North America.

Description
This is a sturdy flight feather from the Canada Goose, a large waterbird known for its black head and neck with a white 'chinstrap'. The bird itself has a brownish back and wings with a pale breast. They are famous for their V-formation flight and loud 'honking' calls.
Colour & Pattern
Uniformly dark fuscous-brown to grayish-black on the dorsal surface. The ventral side is lighter and more silvery. There are no distinct bars or spots, which is typical of the solid dark primaries of this species.
Barb Structure
Densely packed pennaceous barbs on the majority of the vane for structural integrity during flight; plumulaceous (downy) barbs present at the very base (the calamus region) for insulation.
Texture & Surface
Leading edge is very stiff and smooth; the overall vane has a matte to slightly waxy finish, aiding in water repellency. The feather feels rigid and durable.
Key Features
Large size, strong asymmetry, solid dark brown/black coloration, and a distinctively thick, light-colored rachis.
Habitat
Found in a wide variety of habitats including lakes, ponds, bays, marshes, grain fields, and frequently in urban parks, golf courses, and lawns.
Geographic Range
Native to North America; breeding across Canada and the northern US, with many populations now permanent residents across the lower 48 states. Extensively introduced to Europe and New Zealand.
Ecological Role
Primary herbivore; they graze on grasses and aquatic plants. They serve as prey for large raptors and ground predators and are often indicators of local water quality.
Similar Species
Mute Swan (larger, white), Turkey Vulture (darker, lacks the light rachis contrast), or Snow Goose (white with black tips).
Interesting Facts
Canada Geese often remain in family groups; the young (goslings) stay with their parents for an entire year. They are one of the most successful urban-adapted wildlife species.
Condition Notes
Good condition. There is slight fraying at the tip and along the trailing edge, suggesting it was likely a naturally molted feather rather than one lost to predation.
