Likely Rock Pigeon (also Feral Pigeon or Common Pigeon); identification is tentative from the feather alone.

A long gray flight feather, most consistent with a pigeon or dove, though the image alone does not confirm species. Rock Pigeons are stout birds with two dark wing bars and often iridescent necks; their rapid, direct flight is accompanied by audible wing claps in some displays.

Mostly slate gray-brown, with subtle darker bars or mottling and a pale tan rachis. No obvious iridescence is visible; lighting and wear may affect the apparent color.

Pennaceous vanes with interlocking barbs; the feather looks worn or separated in places, and no aftershaft is clearly visible.

The straight, pale central shaft is prominent; gray barbs form broad vanes, with irregular, slightly frayed edges.

Appears matte and fairly stiff, with loose or worn barbs near the tip and base.

Probably from the wing: its long, stiff rachis and asymmetrical vane are typical of flight feathers.

Long, asymmetric flight-feather outline, gray-brown coloration, and a pale rachis. These traits suggest a pigeon-sized bird but are not species-diagnostic.

Rock Pigeons thrive on cliffs and rocky coasts, but also occupy cities, farms, and other human-modified places; they nest on ledges and buildings.

Columba livia is native to parts of Europe, North Africa, and western Asia; feral populations now occur worldwide. Many city birds are resident.

Wild Rock Pigeons forage on seeds and grains and serve as prey for raptors; urban populations are adaptable and widespread. The species is globally secure, though local abundance varies.

Mourning Dove and other pigeon feathers can be similar; size, pattern, and rachis details help, but a single gray feather is rarely conclusive.

Rock Pigeons were domesticated thousands of years ago and are the ancestors of domestic and feral pigeons. Their homing ability has been used for message-carrying.

Pigeons have a long history in food, sport, and message delivery; their feathers have also been used in crafts and fly-tying. Feather possession and trade may be regulated depending on species and location.

Compare with a complete wing or reliable feather guides and use a ruler for scale. Check local regulations before collecting or keeping wild bird feathers.

Visible edge wear and some separated barbs; overall condition appears fair. No clear evidence of active growth, fault bars, or contamination is visible.
