Description
A classic primary feather from the Canada Goose, a large waterbird with a distinctive black head and neck 'sock' and white chin strap. The feather is engineered for powerful, sustained flight across vast migratory distances.
Colour & Pattern
Uniformly dark brownish-black to charcoal gray on the dorsal surface; the ventral side is slightly paler with a silvery-gray sheen. No banding or spots present.
Barb Structure
Densely packed and tightly interlocked (pennaceous) throughout the vane for aerodynamic efficiency; plumulaceous (fluffy) structure is visible only at the very base near the calamus.
Texture & Surface
Varies from smooth and stiff to slightly oily; the surface is matte with a slight waxy bloom that provides water resistance (hydrophobic).
Key Features
Contrast between dark vane and light-colored rachis; asymmetrical vane width; large size; stiff, waterproof pennaceous structure.
Habitat
Extremely versatile; found in wetlands, ponds, lakes, rivers, grassy fields, city parks, and suburban golf courses.
Geographic Range
Widespread across North America; breeds from the Arctic to the southern US and winters throughout much of the United States and Mexico.
Ecological Role
Primary herbivore and seed disperser; serves as a food source for large predators and helps cycle nutrients through wetland ecosystems.
Similar Species
Mute Swan (larger, all white), Snow Goose (smaller, white or darker with different notch), or Wild Turkey (distinctive banding/striping).
Interesting Facts
Canada Geese frequently fly in a V-formation to reduce wind resistance for the birds following the leader, increasing their flight range by up to 71%.
Condition Notes
Good condition; minor fraying at the tip and along the trailing edge suggests it was naturally molted. The calamus appears intact.
