Description
A large, monochromatic dark feather from the iconic Canada Goose. The goose itself features a black head and neck with a distinctive white 'chinstrap', a brownish body, and a pale chest. They are known for their 'honking' calls and V-formation flight patterns.
Colour & Pattern
Solid dark brownish-black to charcoal grey on the dorsal surface. The ventral (underside) is a lighter silvery-grey. No banding or spots are present.
Barb Structure
Densely packed pennaceous barbs that are tightly interlocked for aerodynamics and water resistance; the base features a small plumulaceous (downy) section for insulation.
Texture & Surface
Stiff and smooth with a slight waxy/oily surface typical of waterfowl to provide waterproofing. The vane is firm and holds its shape well when flexed.
Key Features
Large size, dark brownish-black coloration, sturdy white rachis, and the characteristic water-resistant texture of waterfowl feathers.
Habitat
Found in a wide variety of habitats near water, including lakes, ponds, rivers, marshes, and man-made environments like parks, golf courses, and agricultural fields.
Geographic Range
Native to North America, breeding from the Arctic to the southern United States. They are also widely introduced and established in Europe, New Zealand, and parts of Asia.
Ecological Role
Primary herbivores that influence plant community structure through grazing. They also serve as a prey species for large predators and are indicators of wetland health.
Similar Species
Similar to feathers from the Greylag Goose or large Gulls, but the Canada Goose feather is darker than most gulls and lacks the mottled patterns of many domestic goose breeds.
Interesting Facts
Canada Geese are known for their strong pair bonds and will often mate for life. They are also famous for their aggressive defense of nesting sites.
Condition Notes
Good condition; slight fraying at the tip and along the leading edge suggests it was a naturally molted feather rather than one lost to trauma.
