Likely Rock Pigeon (Feral Pigeon; also called Rock Dove), though the feather alone is not diagnostic.

This is a gray-and-white feather with a dark terminal area, consistent with several pigeon or dove plumages but not uniquely identifying a species. Rock Pigeons are stocky birds with two dark wing bars, iridescent necks, and rapid, direct flight.

Pale gray to whitish center with dark charcoal-gray shading across the rounded tip and narrow darker edging. No obvious bars or spots are visible; lighting and the unseen reverse may affect apparent color.

Closely joined, pennaceous vanes; the tip looks mildly frayed, while the shaft and most barbs appear intact.

Straight, slender, pale rachis runs centrally through the feather. Barbs form a smooth, dense vane, with darker coloration concentrated toward the distal end.

Smooth, matte-to-slightly-silky surface; the vane appears firm and well interlocked, with some unevenness at the tip.

Possibly tail or wing, based on its broad, firm vane; the visible shape is insufficient to distinguish these reliably.

Pale gray-white vane, dark rounded tip, and sturdy central shaft; these traits are suggestive but shared by many birds.

Rock Pigeons thrive in cities, farmland, cliffs, and open country, nesting on ledges and building structures and feeding mostly on the ground.

Native across parts of Europe, North Africa, and western to central Asia; feral populations occur worldwide. Generally resident, with local movements.

Pigeons consume seeds and grains and serve as prey for urban raptors, including Peregrine Falcons. Feral populations are widespread; conservation status of the wild ancestral species varies regionally.

Mourning Dove, Eurasian Collared-Dove, and other gray pigeons can have similarly pale feathers with dark tips; exact pattern, measurements, and locality are needed to separate them.

Rock Pigeons were domesticated thousands of years ago and have been used as messengers; many feral city pigeons descend from domestic birds.

Pigeon feathers have been used in crafts and fly-tying, but possession or trade rules vary by location and species. Do not assume an unidentified feather is legally unrestricted.

Photograph both sides beside a ruler and note the collection location. Compare patterns with a regional feather guide; avoid relying on color alone.

Appears generally intact and clean, with slight tip wear or fraying; condition: Good. No clear fault bars, parasites, or oiling are visible.
