Canada Goose (alternate names: Canadian Goose, Wild Goose)

A long, dark primary feather from a large waterfowl. The Canada Goose is a large brown-bodied bird with a black neck and head and a distinctive white cheek patch. In flight, they are known for their iconic 'V' formation and loud honking vocalizations.

Uniform charcoal grey to brownish-black on the dorsal surface. The ventral (underside) surface typically appears lighter or more silvery. There are no distal bands or spots, which is diagnostic for this species' flight feathers.

Tightly interlocked pennaceous structure. The barbs are stiff and hooked with microscopic barbicels to create a wind-resistant surface. The base shows a small amount of plumulaceous (downy) barbs near the superior umbilicus.

The surface is smooth, stiff, and somewhat matte to slightly satiny. Geese produce uropygial gland oils that give the feather a somewhat waxy, water-repellent texture.

Large size, extreme asymmetry, solid dark grey/black coloration without markings, and a thick, pale rachis.

Found in a wide variety of habitats including lakes, ponds, bays, marshes, grain fields, and frequently urban parks, golf courses, and lawns.

Native to Arctic and temperate regions of North America; occasionally reaches northern Europe. They are migratory in northern populations but increasingly resident (non-migratory) in temperate urban areas.

Primary consumer/herbivore; they play a role in seed dispersal but can also cause nitrogen loading in small ponds due to high density. They are a staple prey for large predators like bald eagles and coyotes.

Mute Swan (larger, usually pure white), Brant (smaller feather), or Black Vulture (similar color but different rachis structure and broader shape).

Canada Geese usually mate for life. They are famous for their precise migration patterns, often returning to the exact same nesting ground year after year.

Excellent condition. The vane is intact without significant fraying or 'fault bars' (weakness lines from nutritional stress). The calamus (quill) is clear, suggesting a healthy molt.
