Canada Goose (alternate names: Wild Goose, Northern Goose)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Anseriformes, Family: Anatidae, Genus: Branta, Species: Branta canadensis · Anatidae (Ducks, Geese, and Swans) · Secondary Flight Feathers (Remiges)
Species
Branta canadensis (High confidence)
Feather Type
Secondary Flight Feathers (Remiges)
Family
Anatidae (Ducks, Geese, and Swans)
Shape
Generally asymmetrical with a broader trailing vane and narrower leading vane; rounded tips. Broad and slightly curved overall profile.
Size
Approximately 18–22 cm (7–9 inches) in length. Consistent with the mid-to-outer secondary range for a large-bodied Canada Goose species.
Rarity
Very Common; one of the most widespread and easily recognized waterfowl in the Northern Hemisphere.
Color & Pattern
Dull brownish-gray to charcoal-brown base color. The leading edge is noticeably darker (blackish) than the trailing edge. There is a characteristic light tan or pale gray wash towards the inner vane. No bold banding or iridescence is present, which is typical for this species' wing feathers.
Barb Structure
Tightly interlocked pennaceous structure throughout the majority of the vane for flight efficiency; plumulaceous (downy) at the base near the calamus for insulation.
Texture & Surface
Smooth and somewhat waxy surface, providing significant water-repellency. Stiff and rigid vane with a matte finish. The trailing edge is softer than the leading edge.
Description
These are robust flight feathers from the Canada Goose, a large waterfowl known for its black head and neck with a white 'chinstrap.' The bird itself has a brownish back and wings with a light chest. They are famous for their V-formation flight patterns and loud 'honking' calls.
Key Features
Large size, two-tone brown coloration (dark leading edge, lighter trailing edge), thick white/pale rachis, and the presence of significant downy fluff at the base.
Habitat
Found near water sources including lakes, ponds, bays, marshes, and fields. Frequently seen in urban parks, golf courses, and agricultural lands.
Geographic Range
Native to Arctic and temperate regions of North America, having a range extending across the USA and Canada. Successfully introduced to Europe, New Zealand, and parts of Asia.
Condition Notes
Fair to Good. There is visible wear and separation of the barbs ('zipper' failure) along the edges, suggesting these were naturally molted feathers rather than freshly grown.
Interesting Facts
Canada Geese can travel up to 1,500 miles in a single day if the weather conditions are favorable. They are known for their lifelong pair bonds and strong family units.
Ecological Role
Primary grazers that help cycle nutrients from aquatic to terrestrial environments. They serve as a food source for large predators and can influence plant community structures through grazing.
