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 with a very narrow leading vane (outer vane) and a broad trailing vane (inner vane). The tip is pointed and the overall structure is elongated and curved.
- Size
- Estimated 10-14 inches (25-35 cm) in length. This is consistent with a large primary from an adult Canada Goose.
- Rarity
- Very Common; one of the most widely recognized and abundant waterfowl species in the Northern Hemisphere.

Description
This is a primary flight feather from a Canada Goose, a large waterbird with a black head and neck, white 'chinstrap', and brownish body. These feathers are engineered for powerful, sustained flight and the characteristic V-formation migrations.
Colour & Pattern
Dull brownish-black to dark charcoal on the distal half, fading to a lighter brownish-gray or creamy white towards the proximal base. The trailing vane is lighter than the leading vane.
Barb Structure
Pennaceous and tightly interlocked for aerodynamic integrity; the base shows some plumulaceous (downy) barbs. The distal end shows some wear and separation of the barbs.
Texture & Surface
Stiff and relatively coarse. The surface is matte with a slightly oily, water-repellent coating typical of waterfowl.
Key Features
Significant asymmetry, large size, stiff calamus, and the specific gradient of dark charcoal/black to creamy white at the base.
Habitat
Extremely versatile: found in lakes, ponds, rivers, marshes, grain fields, and frequently in urban parks, golf courses, and suburban lawns.
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 non-migratory.
Ecological Role
Primary herbivore that grazes on grasses and aquatic plants; they serve as prey for large predators and their droppings contribute nutrients to aquatic ecosystems.
Similar Species
Snow Goose (shorter, often whiter bases), Mute Swan (significantly larger and pure white), or Greater White-fronted Goose (slightly different color tone).
Interesting Facts
Canada Geese can travel over 1,000 miles in a single day during migration and are known for their strong mate bonds, often staying together for life.
Condition Notes
Fair to Good. There is notable fraying at the tip and separation of the barbs along the trailing edge, suggesting this was a molted feather that has seen significant use.
