Canada Goose (also known as Wild Goose or Canadian Goose)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Anseriformes, Family: Anatidae, Genus: Branta, Species: Branta canadensis · Anatidae (Ducks, Geese, and Swans) · Flight feather (Remiges), likely a mid-inner Primary or an Outer Secondary (remex)
Species
Branta canadensis (High confidence)
Feather Type
Flight feather (Remiges), likely a mid-inner Primary or an Outer Secondary (remex)
Family
Anatidae (Ducks, Geese, and Swans)
Shape
Asymmetrical with a narrower leading edge and a broader trailing edge; the tip is rounded to slightly blunted. Elongated and slightly curved profile.
Size
Estimated 7 to 9 inches (18-23 cm) in length. This is consistent with the primary or secondary feathers of a large waterfowl like the Canada Goose.
Rarity
Very Common. One of the most widespread and easily observed large birds in North America.
Color & Pattern
Uniform dark brownish-gray to charcoal on the vanes. The base transitions into a lighter gray or whitish downy section. Both surfaces are relatively matte, though the ventral side is slightly paler with a silvery sheen.
Barb Structure
Densely packed pennaceous barbs throughout the distal portion for aerodynamic integrity; plumulaceous (fluffy) barbs at the base for insulation. Barbules are tightly interlocked with hooklets.
Texture & Surface
Very stiff and durable texture. The surface is smooth and features a waxy, water-repellent coating characteristic of waterfowl. The leading edge is noticeably firmer than the trailing edge.
Description
This is a sturdy flight feather from a Canada Goose, a large waterbird known for its black head and neck with a distinctive white 'chinstrap'. These birds have a brownish back and wings with a pale breast. They are famous for their V-shaped flight formations and loud 'honking' calls.
Key Features
The combination of the large size, charcoal-brown uniform color, off-white thick rachis, and water-resistant texture is diagnostic for large Anatidae, specifically Branta.
Habitat
Found in a wide variety of habitats near water including lakes, ponds, rivers, marshes, and urban areas like parks, golf courses, and agricultural fields.
Geographic Range
Native to Arctic and temperate regions of North America; widely introduced to Europe, New Zealand, and South America. Highly migratory in northern populations.
Condition Notes
Good condition. There is minor fraying at the tip and along the trailing edge, suggesting it was molted naturally rather than lost to trauma. No significant sun-bleaching or parasite damage is visible.
Interesting Facts
Canada Geese often remain in the same mated pairs for life and are highly protective of their nests. They exhibit a 'molt migration' where non-breeding birds fly north to safer areas to shed and regrow their feathers.
Ecological Role
They act as significant grazers and can influence local vegetation. They are also a prey species for large predators and contribute to nutrient cycling between water and land.
