Large white domestic fowl; most likely a domestic goose (also called farm goose), though a large white domestic duck or other poultry cannot be excluded.

A long, mostly white feather with a narrow, asymmetric vane and pale shaft, consistent with a large domestic waterfowl. A goose-sized bird would have a heavy body, webbed feet, and a broad wingspan; breed and behavior cannot be determined from this feather.

Predominantly white to pale ivory, with a light tan rachis; no clear bands, spots, or iridescence. White plumage is common in domestic goose breeds.

Pennaceous vanes with interlocking barbs; several lower barbs appear separated or bent. No obvious aftershaft is visible.

Straight, pale, moderately stout shaft; fine white barbs angle outward, with uneven spacing and some loose sections near the base.

Soft-looking, matte vane with a relatively firm shaft; parts of the vane appear ruffled or separated.

Likely wing, probably a secondary flight feather, based on its broad, soft-looking vane and pronounced asymmetry.

Large size, white coloration, pale rachis, and strongly asymmetric flight-feather shape support domestic waterfowl; these traits do not reliably distinguish goose from duck.

Domestic geese occur on farms, parks, and ponds, using grassy areas and wetlands for feeding and roosting.

Domestic geese are kept worldwide; their wild ancestor, the Greylag Goose, is native to Europe, North Africa, and western Asia, with some populations migratory.

Domestic geese graze vegetation and may affect pond edges and lawns; they are not a wild population indicator. Greylag Geese contribute to wetland food webs and seed dispersal, with local populations affected by habitat change and hunting.

Large white domestic duck feathers can look similar; goose feathers are often larger, but overlap is substantial. Swan or other white waterfowl feathers also require comparison with a reliably identified specimen.

Domestic geese descend chiefly from Greylag Geese, while some breeds have Swan Goose ancestry. Geese are strong grazers and communicate with loud honks and calls.

Goose feathers and down have historically been used for bedding, insulation, writing quills, and crafts. Laws and ethical concerns vary by species and source; do not collect feathers from protected wild birds without checking local regulations.

Record length, shaft shape, vane asymmetry, and nearby bird species; photographs with a ruler aid comparison. Avoid assigning a wild species from white color alone.

Visible vane separation and slight fraying; no obvious staining or severe breakage. Overall condition appears fair to good; age and molt stage cannot be determined.
