Canada Goose (also known as Wild Goose or Honker)
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 outer vane and a broad inner vane; the tip is attenuated and pointed, showing a distinct distal notch (emargination) typical of high-performance flight feathers.
- Size
- Approximately 10 to 12 inches (25-30 cm) in length. This is consistent with the primary flight feathers of a large-bodied Canada Goose.
- Rarity
- Very Common; one of the most widespread and easily recognized waterfowl in the Northern Hemisphere.

Description
This is a primary flight feather from the iconic Canada Goose, a large waterfowl known for its black head and neck with a white 'chinstrap.' In flight, these feathers form the powerful wingtips that allow them to fly in V-formations. The bird itself can have a wingspan of up to 5.5 feet.
Colour & Pattern
Solid dark brownish-black to charcoal gray on the vanes. The dorsal surface is slightly darker and more lustrous than the ventral side. There is a characteristic contrast between the dark vane and the strikingly pale, creamy-white rachis.
Barb Structure
Densely packed and tightly interlocked pennaceous barbs designed for aerodynamic thrust. The base of the vane shows a small amount of softer, downy plumulaceous barbs near the superior umbilicus.
Texture & Surface
Smooth, stiff, and somewhat oily to the touch, providing water-repellent qualities. The vane has a slight satiny sheen, while the rachis is hard and polished.
Key Features
Large size, extreme vane asymmetry, uniform dark charcoal/brown coloration, and a notably thick, pale ivory-white rachis (quill).
Habitat
Extremely versatile; found in lakes, ponds, bays, marshes, grain fields, and frequently in urban parks, golf courses, and residential areas near water.
Geographic Range
Native to North America, breeding across Canada and the Northern US. Many populations migrate to the Southern US and Mexico, though many urban populations are now year-round residents.
Ecological Role
Primary herbivores that graze on grasses and grains; they serve as a food source for large predators and contribute to nutrient cycling in wetlands.
Similar Species
Similar to feathers from the Cackling Goose (Branta hutchinsii), but significantly larger. Can be distinguished from Mute Swan primaries by the dark color (swans are white) and from large raptors by the uniform color and lack of banding.
Interesting Facts
Canada Geese are famous for their V-shaped migratory formations, which reduce wind resistance for the birds behind the leader. They are also known to mate for life and are fiercely protective of their nests.
Condition Notes
Good condition. The feather appears to be a naturally molted specimen. The vane shows minor separation (splits) consistent with natural wear and tear or exposure after molting.
