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, with a very narrow and stiff leading edge (outer vane) and a broad trailing edge (inner vane). The tip is rounded, and the overall profile is elongated and slightly curved.
- Size
- Estimated at 10 to 12 inches (25-30 cm) in length. This is consistent with the mid-to-outer primary feathers of a large-bodied Canada Goose.
- Rarity
- Very Common; the Canada Goose is one of the most widespread and easily recognized waterfowl in North America.

Description
This is a large, sturdy primary feather from a Canada Goose. The bird itself is a large waterfowl with a black head and neck, a white 'chinstrap' mark, and a brownish-gray body. They are famous for their V-shaped flight formations and loud 'honking' calls.
Colour & Pattern
Uniformly dark brownish-gray to charcoal on the dorsal surface, with a slightly lighter, silvery-gray sheen on the ventral side. No banding or spotting is present, which is characteristic of this species.
Barb Structure
Tightly interlocked pennaceous barbs on the majority of the vane for aerobic efficiency; the base transitions into a soft, plumulaceous (downy) structure near the calamus.
Texture & Surface
The surface is smooth, stiff, and somewhat oily to the touch, providing water-repellent properties. The leading edge is extremely firm to withstand air pressure during flight.
Key Features
Large size, uniform dark brownish-gray coloration without markings, significant vane asymmetry, and a very thick, rigid rachis.
Habitat
Found in a wide variety of habitats near water, including lakes, ponds, marshes, rivers, grain fields, and frequently in suburban areas like parks and golf courses.
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 grazers that help cycle nutrients between aquatic and terrestrial environments; they also serve as a significant prey source for large predators.
Similar Species
Similar to feathers from the Snow Goose (which are white with black tips) or the Domestic Goose (often pure white). Distinguishable from Bald Eagle feathers by the lack of mottling even at the base.
Interesting Facts
Canada Geese are known for their strong mate-pairing, often staying together for life. They are also incredibly protective parents, frequently 'hissing' to defend their goslings.
Condition Notes
The feather appears to be in Good to Excellent condition, likely a naturally molted specimen. The vanes are mostly intact with very little fraying or environmental wear.
