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, stiff leading edge (outer vane) and a broad trailing edge (inner vane); the tip is rounded-tapered with a distinct curve.
- Size
- Estimated 10-14 inches (25-35 cm) in total length. This is a large, robust feather consistent with the primary wings of an adult Canada Goose.
- Rarity
- Very Common. One of the most widespread and easily observed large birds in the Northern Hemisphere.

Description
The Canada Goose is a large waterfowl with a distinctive black head and neck and a white 'chinstrap.' Its body is brown above and tan below. The wings are large and powerful, adapted for long-distance migration in V-formations. They are known for their loud 'honking' calls and aggressive nesting behavior.
Colour & Pattern
Uniformly dark fuscous-brown to charcoal grey on the dorsal surface; the ventral surface is slightly paler with a silvery-grey sheen. There are no bands or spots. The rachis is dark on top and lightens toward the calamus.
Barb Structure
Densely pennaceous and tightly interlocked to provide a rigid, aerodynamic surface capable of sustaining the bird’s heavy body in flight. The barbs are extremely stiff near the rachis.
Texture & Surface
Smooth, stiff, and somewhat oily to the touch for waterproofing. The surface has a matte to slightly satiny finish typical of waterfowl remiges.
Key Features
Large size, uniform dark brown coloration, extreme asymmetry of the vanes, and a thick, yellowish-white calamus without decorative patterning.
Habitat
Extremely versatile: found in wetlands, marshes, lakes, ponds, rivers, and increasingly in urban parks, golf courses, and agricultural fields.
Geographic Range
Native to North America, breeding from the Arctic to the southern United States; winters south to Mexico. Introduced widely in Europe, New Zealand, and South America.
Ecological Role
Primary grazer of grasses and aquatic plants; they play a significant role in nutrient cycling, though their high populations in urban areas can lead to water quality issues.
Similar Species
Cackling Goose (nearly identical but smaller), Snow Goose (typically white or blue-gray), and Mute Swan (significantly larger and usually white).
Interesting Facts
Canada Geese are famous for their V-shaped flight formations, which reduce air resistance for the trailing birds. They often mate for life and are highly protective of their goslings.
Condition Notes
Fair to Good. The feather shows signs of environmental wear, including small nicks in the trailing vane and some separation of the barbs ('zipper' failure), likely a naturally molted feather.
