Canada Goose (Greater Canada Goose)

This is a primary flight feather from a Canada Goose, a large waterbird with a black head and neck, white 'chinstrap', and brownish body. These birds are known for their V-shaped flight formations and loud 'honking' calls. An adult's wingspan can reach 5.5 feet, requiring these large, stiff feathers to support their heavy weight during long-distance migration.

Solid brownish-black to charcoal gray on the dorsal surface; the ventral side is slightly paler and more silvery. The rachis is white to cream-colored at the base, darkening toward the tip. No banding or spots are present.

Densely interlocked pennaceous barbs on the distal portion for aerodynamic rigidity; plumulaceous (downy) barbs present at the base for insulation. Barbs are intact but show some separation toward the tip.

Stiff and relatively smooth with a matte finish. The surface has a slightly waxy/oily feel, providing water-repellent properties essential for waterfowl.

Large size, brownish-black color, heavy white rachis at base, and the significant narrowing (emargination) of the leading vane near the tip.

Found near freshwater lakes (like Lake Sammamish), ponds, marshes, and also common in agricultural fields, suburban lawns, and urban parks.

Native to Arctic and temperate regions of North America. Found year-round in Washington State; northern populations migrate south to the United States and Mexico in winter.

Primarily herbivores that graze on grasses and aquatic plants. They serve as a food source for large predators and can influence local plant communities through grazing.

Cackling Goose (Branta hutchinsii) feathers are nearly identical but smaller. Trumpeter Swan feathers are much larger and usually white. Large gull feathers (like Glaucous-winged Gull) are more gray and usually have white spots (apical spots) at the tips.

Canada Geese are known to fly in a 'V' formation to reduce wind resistance for the birds behind the leader. A single bird can have between 20,000 and 25,000 feathers.

Good condition; showing typical 'feather separation' at the edges likely from impact with the ground or wind wear. No significant sun bleaching or parasite damage is visible.
