Family: Anatidae (Ducks, Geese, and Swans)
- Shape
- Slightly asymmetrical with a rounded tip and a broad vane. The leading edge (outer vane) is narrower than the trailing edge (inner vane) but less dramatically so than a primary feather.
- Size
- Estimated 15-20 cm in length. This matches the standard secondary feather size for an adult Canada Goose.
- Rarity
- Very Common; one of the most widespread and easily identified large birds in North America.

Description
This feather is a classic secondary flight feather from a Canada Goose. The bird itself is a large waterfowl known for its iconic black head and neck with a white 'chinstrap.' It has a heavy body, long neck, and large webbed feet. In flight, they are famous for their V-formation and loud honking vocalizations.
Colour & Pattern
Predominantly matte charcoal-grey to dark brownish-black. The inner vane shows a slightly lighter grey-brown gradient. There is a distinct, clean white/pale rachis that stands out against the dark pigmentation.
Barb Structure
Tightly interlocked pennaceous barbs designed for aerodynamic integrity and water resistance. The base transitions into a short plumulaceous (downy) section near the calamus.
Texture & Surface
The surface is stiff, smooth, and slightly oily to the touch, providing essential waterproofing. The vane is rigid and holds its shape well when under pressure.
Key Features
Broad dark grey-brown vane, white rachis, rounded tip, and a stiff texture characteristic of waterfowl flight feathers.
Habitat
Extremely versatile; found in wetlands, lakes, rivers, ponds, city parks, golf courses, and agricultural fields. They prefer open areas with clear lines of sight.
Geographic Range
Widespread throughout North America, breeding from the Arctic to the southern United States. They are migratory but many populations are now year-round residents in urban areas.
Ecological Role
As herbivores, they play a role in seed dispersal and vegetation management, though large numbers in urban areas can lead to nutrient loading in small ponds.
Similar Species
May be confused with the feathers of a Snow Goose (which would be white) or a Great Blue Heron (which is more blue-grey and has a different barb texture). Mallard wing feathers are much smaller.
Interesting Facts
Canada Geese are known for their strong pair bonds, often mating for life. During their annual molt, they lose all their flight feathers at once and are unable to fly for about 6 weeks.
Condition Notes
The feather appears to be in Good condition with some minor wear at the tip and separation of the barbs near the base (calamus). It is likely a naturally molted feather.
