- Shape
- Asymmetrical vane typical of flight feathers; the leading edge is narrower and stiffer than the trailing edge. Elongated with a gently rounded but tapering tip.
- Size
- Approximately 9 to 11 inches in length (23-28 cm). This size is consistent with the primary flight feathers of a medium-to-large Canada Goose.
- Rarity
- Very Common; one of the most widely recognized and abundant large birds in North America.

Description
This is a large, sturdy flight feather from a Canada Goose. The bird itself is a large waterbird with a distinctive black head and neck, white cheek patches, and a brownish body. They are known for their 'V' flight formations and loud honking calls.
Colour & Pattern
Solid dark brownish-black to charcoal grey. The dorsal surface is slightly darker and more matte; the ventral surface has a subtle silvery-grey sheen. No banding or spots are present.
Barb Structure
Tightly interlocked pennaceous barbs throughout most of the vane for aerodynamic integrity, becoming slightly plumulaceous (fluffy) only at the very base near the calamus.
Texture & Surface
Smooth, stiff, and water-repellent. The surface has a slight waxy bloom, typical of waterfowl. The leading edge (vane) is very rigid to withstand flight pressure.
Key Features
Large size, solid dark brownish-black color, ivory-white thick rachis at the base, and extreme sturdiness characteristic of heavy-bodied waterfowl.
Habitat
Temperate regions near water including lakes, rivers, ponds, marshes, and increasingly common in urban parks, golf courses, and suburban lawns.
Geographic Range
Native to North America; breeds across Canada and the northern US. Widely introduced to Europe, New Zealand, and South America. Many populations are now non-migratory / resident in urban areas.
Ecological Role
Primary herbivore; they graze on grasses and aquatic plants. They serve as prey for large predators and their waste contributes nutrients to aquatic ecosystems.
Similar Species
Wild Turkey (feathers usually have iridescent sheen or different banding), Domestic Goose (often white or lighter grey), and Black Vulture (rachis is typically darker and feather shape is broader).
Interesting Facts
Canada Geese have between 20,000 and 25,000 feathers. During their annual summer molt, they lose all their flight feathers at once and are unable to fly for about 6 weeks.
Condition Notes
Good to Fair. There is some minor 'zipper' separation of the barbs (splitting) near the trailing edge, likely from hitting the ground or light wear prior to molting.
