Likely Canada Goose (also Canadian Goose)

This substantial two-toned wing feather likely came from a Canada Goose, a large, long-necked goose with a black head and neck, white cheek patch, and brown body. Canada Geese fly in powerful V-formations and give the familiar resonant honking calls.

Warm cream to white lower vane with a dark brown-black distal area, separated by an irregular transition; rachis pale yellow. Pattern is compatible with Canada Goose wing feathers, though exact species cannot be confirmed from one feather

Pennaceous and tightly interlocked through most of the vane, becoming loose and downy near the base; no owl-like comb edge

Stout, straight, yellowish rachis; barbs are dense and smooth distally, with a fluffy aftershaft and loose basal barbs

Smooth, moderately glossy, and water-resistant over the pennaceous vane; base is soft and downy

Wing, inferred from asymmetry, stiff vanes, and dark terminal pattern

Large size, pale cream lower vane, sharply contrasting dark tip, yellow rachis, and loose basal down are the strongest clues; the image does not permit a secure species-level identification

Ponds, marshes, rivers, agricultural fields, parks, and urban waterways; nests near water and forages in grasses and crops

Widespread across North America, with introduced or established populations in parts of Europe and elsewhere; many northern birds migrate, while temperate populations are resident

A major grazer and seed disperser that also supplies prey and carrion to predators; large urban populations can overgraze lawns and enrich waterways, making population management locally important

Greylag Goose and domestic goose feathers can be similar, but often differ in size and pattern; swan feathers are usually much larger and whiter, while duck feathers are generally smaller

Canada Geese can navigate long migrations using visual landmarks, celestial cues, and geomagnetic information; some populations now remain year-round in cities because food and open water are readily available

Goose feathers have historically been used for insulation, quill pens, fly-tying, decorative arts, and down garments. In the United States, possession of wild migratory bird feathers is generally regulated under the Migratory Bird Treaty Act

Search beneath communal roosts, along pond margins, and near moulting areas in late summer. Compare multiple feathers from the same wing and use size, vane asymmetry, rachis color, and pattern together

Apparently naturally molted and intact, with some basal fraying and minor distal wear; no obvious fault bars, parasites, oil, or bleaching. Condition: Good
