Family: Anatidae (Ducks, Geese, and Swans)
- Shape
- Asymmetrical vane characteristic of flight feathers, with a narrower leading edge and broader trailing edge. The tip is rounded and slightly tapered.
- Size
- Estimated at 7-9 inches (18-23 cm) in length. This is consistent with the inner primary range for a large Canada Goose specimen.
- Rarity
- Very Common. One of the most abundant and easily recognized waterfowl in North America.

Description
A large, heavy-bodied waterfowl with a long black neck, black head, and a distinctive white 'chinstrap' mark. The body is brown-grey with a pale breast. In flight, they are known for their iconic V-formation and loud honking calls.
Colour & Pattern
Uniformly dark brownish-grey to charcoal on the dorsal surface. The ventral side is lighter and more silvery. The rachis is pale cream to white, providing a sharp contrast against the dark vanes.
Barb Structure
Densely packed pennaceous barbs with well-developed interlocking barbules (hooklets) for flight efficiency. The base shows a small cluster of plumulaceous (downy) barbs near the superior umbilicus.
Texture & Surface
Smooth and stiff. The surface has a matte to slightly waxy finish, which helps with water repellency. The leading edge is noticeably firmer than the trailing edge.
Key Features
Solid dark grey/brown coloration, significantly asymmetrical vanes, and a prominent, light-colored (ivory) rachis. The size and stiffness are characteristic of heavy-bodied waterfowl.
Habitat
Found in a variety of habitats near water, including lakes, ponds, rivers, marshes, and man-made environments like golf courses and city parks (such as Rene-Levesque Park).
Geographic Range
Native to North America; widespread across Canada and the United States. Many populations are migratory, though urban residents in Montreal are often year-round or short-distance migrants.
Ecological Role
Major herbivore and seed disperser. They play a significant role in nitrogen cycling in urban parks, though high populations can lead to water quality issues (eutrophication).
Similar Species
Snow Goose (feathers are white with black tips), Brant (smaller, darker), or Mute Swan (significantly larger and white). Cackling Goose feathers are nearly identical but slightly smaller.
Interesting Facts
Canada Geese often mate for life and are highly protective of their nests. They are famous for their migratory 'V' formation, which reduces wind resistance for the birds flying behind the leader.
Condition Notes
Good. The feather appears fresh with minimal fraying. There are no obvious signs of parasite damage (lice holes) or severe sun-bleaching.
