Likely a crow (crow feather; exact species uncertain).

A long, dark, gently curved feather consistent with a medium-to-large bird’s wing feather. The image does not show diagnostic markings sufficient to identify the bird or confidently separate crow from other dark-feathered species.

Dark brown to charcoal with subtle lighter brown areas; no clear barring or distinctive markings are visible. Lighting and wear may affect the apparent color.

Vane is compact and pennaceous, with barbs mostly held together; some looseness or wear is visible near the base.

Pale gray-brown shaft, relatively straight and sturdy; barbs form a smooth, even vane, with apparent disruption near the calamus.

Mostly smooth and matte, with a firm-looking vane and slightly ragged basal area.

Probably from the wing, based on its elongated shape and unequal vanes; exact placement cannot be established.

Dark uniform appearance, elongated outline, and pale shaft; none is uniquely diagnostic of a crow.

If from a crow, likely varied habitats including woodland, farmland, parks, and urban areas.

Corvus species occur widely worldwide; this specimen’s location and the bird species cannot be identified from the image.

If from a crow, it likely belonged to an omnivorous scavenger and predator that helps remove carrion and may disperse seeds; conservation status cannot be assigned without species identification.

Raven, rook, jackdaw, grackle, and dark-feathered pigeons may have similar feathers; size, gloss, shaft and vane details, and associated location are needed to distinguish them.

Crows are highly adaptable corvids known for problem-solving, complex social behavior, and varied vocalizations.

Feathers have been used in art and craft traditions, but possession and trade restrictions vary by species and jurisdiction; identify the bird before collecting or using it.

Measure the feather and photograph both sides beside a scale; compare with verified regional feather references. Check local laws before keeping wild bird feathers.

Fair condition: vane appears largely intact, with possible fraying or damage near the base; age and molt status are indeterminable.
