Likely domestic pigeon (Rock Pigeon); the handwritten label appears to read “pluma doméstica,” but the specimen’s species cannot be confirmed from the image.

This is a mounted, dark contour-type feather with a rounded end, pale shaft, and loose basal down. A pigeon identification is plausible, but the image does not show enough diagnostic detail to establish species confidently.

Mostly dark brown to charcoal, with pale gray-brown areas and several narrow pale curved marks near the base. Lighting and the mounted presentation make natural color and surface differences uncertain.

The upper vane is compact and pennaceous; the lower base has loose, fluffy barbs. No clear damage or specialized owl-like fringes are visible.

A pale, slender rachis runs through the center; barbs are closely aligned across the broad vane and become loose near the base.

The vane looks smooth and matte, while the basal portion appears soft and fluffy.

Probably body or covert plumage, based on its rounded outline and downy base rather than the long, strongly asymmetrical form of a primary.

Rounded, apparently near-symmetrical vane, fluffy base, and pale curved markings; these features alone are not species-diagnostic.

Rock Pigeons commonly occupy towns, farms, cliffs, and other open habitats with ledges for nesting and nearby food sources.

Domestic and feral birds occur worldwide; the wild ancestral range includes parts of Europe, North Africa, and western and central Asia.

Feral pigeons consume seeds and human food, serve as prey for urban raptors, and can affect local ecosystems; populations are abundant and widespread.

Dove and pigeon contour feathers can look alike; reliable separation generally requires distinctive patterning, measurements, or known provenance.

Rock Pigeons were domesticated thousands of years ago and have been selectively bred into many forms; feral populations thrive in cities worldwide.

Pigeon feathers have been used in crafts and historical fly-tying. Feather collection and trade are subject to wildlife laws, especially for protected species.

Record the find location and photograph both sides beside a scale; compare several feathers from the same site rather than identifying from color alone.

Appears largely intact, though the base is loose or partly disheveled; overall condition looks good. Age, molt stage, and any fading cannot be determined.
