Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Anseriformes; Family: Anatidae; Genus: Branta; Species: Branta canadensis
Family: Anatidae (Ducks, Geese, and Swans)
- Shape
- Asymmetrical vane typical of flight feathers; the leading edge is narrower than the trailing edge; rounded tip with a slight taper; broad outline.
- Size
- Approximately 8 to 10 inches in length, based on the scale of the standard lined notebook paper. This is consistent with the secondary feathers of a large Canada Goose.
- Rarity
- Very Common; one of the most widespread and easily recognizable waterfowl in the Northern Hemisphere.

Description
This is a robust flight feather from a Canada Goose, a large waterbird known for its black head and neck with a white 'chinstrap' mark. The bird has a brownish body and can have a wingspan of up to 5.5 feet. They are famous for their V-shaped flight formations and loud honking calls.
Colour & Pattern
Dark brownish-black to charcoal grey on the upper surface; the underside is a lighter, more matte silver-grey. No banding or spots, which is characteristic of adult plumage in this species.
Barb Structure
Tightly interlocked pennaceous barbs for aerodynamic efficiency; plumulaceous (fluffy) barbs are visible at the very base near the calamus (quill).
Texture & Surface
Texture is smooth and stiff; the vane is somewhat oily or waxy for water resistance; the leading edge is rigid to withstand wind pressure during flight.
Key Features
Uniform dark grey/black coloration, thick pale rachis, large size, and water-resistant texture without any distinct barring or mottling.
Habitat
Extremely versatile; found in wetlands, lakes, rivers, marshes, grassy fields, urban parks, golf courses, and agricultural lands.
Geographic Range
Native to North America; found year-round across the United States; migrates to northern Canada and Alaska for breeding; introduced and widespread in Europe and New Zealand.
Ecological Role
Primarily herbivores that graze on grasses and aquatic plants; they serve as a food source for large predators and help disperse seeds, though large populations in urban areas can lead to nutrient loading in small ponds.
Similar Species
Can be confused with the feathers of a Domestic Goose (often lighter or white), a Snow Goose (white with black tips), or a Mute Swan (entirely white), but the uniform dark grey-black tone is diagnostic for the Canada Goose.
Interesting Facts
Canada Geese are monogamous and remain with the same partner for life. They are highly protective of their nests and can be aggressive toward perceived threats. Some populations are now non-migratory and reside in urban areas year-round.
Condition Notes
Good condition; slight wear at the tip and some separation of the barbs on the trailing edge; calamus appears intact, suggesting it was naturally molted.
