Description
This is a large, sturdy flight feather from a Canada Goose. The bird is characterized by its black head and neck with a distinctive white 'chinstrap.' It is a heavy-bodied waterfowl with a massive wingspan up to 5.5 feet, known for its iconic 'V' formation flight and loud 'honking' calls.
Colour & Pattern
Dull charcoal grey to brownish-black. The color is solid and uniform across the vane, with a slightly lighter, silvery-grey sheen on the ventral (underside) surface. No banding or spots.
Barb Structure
Tightly interlocked pennaceous barbs providing a rigid, aerodynamic surface; plumulaceous (downy) barbs present only at the very base near the calamus.
Texture & Surface
Smooth, stiff, and somewhat oily for water-resistance. The surface has a matte to low-gloss finish, designed to withstand the high pressure of powerful downstrokes.
Key Features
Large size, uniform dark grey-black coloration, asymmetrical vane, and a very thick, pale rachis. Lacks the mottling found in many raptors or the iridescence of other waterfowl.
Habitat
Ubiquitous across wetlands, lakes, ponds, rivers, grassy fields, parks, and urban environments.
Geographic Range
Native to North America; breeds across Canada and the northern US; winters throughout much of the United States and Mexico. Introduced widely in Europe and New Zealand.
Ecological Role
Primarily a herbivore that grazes on grasses and aquatic plants. They serve as a food source for large predators and help cycle nutrients between aquatic and terrestrial ecosystems.
Similar Species
Domestic Goose (often pure white), Greater White-fronted Goose (similar but often smaller/lighter), and Turkey Vulture (which has a distinct silver-grey sheen on the entire underside of the vane and a darker rachis).
Interesting Facts
Canada Geese are known for their strong pair bonds, often mating for life. They are highly successful at living alongside humans and can be quite aggressive when defending their nests or young goslings.
Condition Notes
Good condition with some minor fraying at the tip and trailing edge, suggesting it was likely a naturally molted feather from the post-breeding season.
