Canada Goose

This is a robust primary flight feather from a Canada Goose, a large waterfowl known for its iconic black head and neck with a white 'chinstrap' mark. The feather itself is engineered for powerful, sustained flight and the high-stress demands of migration.

Predominantly dark charcoal gray to brownish-black on the dorsal surface. The ventral side is lighter gray with a silvery sheen. The rachis transition from white at the base to dark near the tip is a key trait.

Tightly interlocked and pennaceous for aerodynamic integrity, with a very stiff and rigid structure. Plumulaceous (downy) barbs are present only at the base.

Very stiff, smooth, and oily/waterproof. The surface has a slight matte finish typical of waterfowl feathers to resist water saturation.

Characteristic long, white, thick calamus (quill base); extreme asymmetry in the vanes; dark charcoal-black coloration; and a total lack of mottling or banding.

Temperate regions near freshwater lakes, ponds, marshes, rivers, coastal lagoons, and increasingly in urban parks and golf courses.

Native to North America, breeding from Alaska across Canada to the northern US, and wintering as far south as Mexico. Also widely introduced in Europe and New Zealand.

Primarily herbivorous, they act as seed dispersers and are important prey for large predators. In urban areas, they are key indicators of local water quality and pond health.

Black Vulture (feather has more silver on the underside and different shape); Great Blue Heron (more blue-gray tone); Mute Swan (entirely white).

Canada Geese often fly in a V-formation to reduce wind resistance for birds behind the leader. They are known for their lifelong pair bonds and their loud 'honking' vocalizations.

The feather appears structurally sound but shows some wear and separation at the tip of the vanes (fraying), common in molted feathers found late in the season.
