Unknown; likely a large parrot or another red-plumaged bird

The specimen is an elongated reddish feather lying on rough pavement. Its narrow, tapered outline suggests a wing feather, but color alone is insufficient to identify the bird; several parrots and other birds have red or chestnut flight feathers.

Deep reddish-brown to russet across most of the vane, with a pale pinkish-red area near the base. No clear bars or spots are visible; lighting and wear may affect the apparent color.

Compact, pennaceous vanes with visible fine barbs; some edges appear slightly frayed.

A slender, pale central rachis runs nearly the full length. Barbs form a dense, smooth-looking vane, with subtle color variation toward the base.

Appears smooth and matte, with a relatively stiff vane; fine surface details are limited by the photograph.

Probably from a wing, based on its elongated form and asymmetric vanes.

Uniform red-brown coloration, pointed tip, and asymmetric vane are visible. A scale, underside view, and exact feather measurements would help narrow the identification.

Cannot be assigned without a reliable species identification.

Cannot be determined from this feather alone.

Species-specific ecological or conservation information cannot be assigned without identification; feathers themselves provide insulation, waterproofing, and flight surfaces in birds.

Red and chestnut feathers occur in macaws, other parrots, and various pheasants and gamebirds. Shape, full plumage pattern, location, and measurements are needed to distinguish them.

Feather colors can arise from pigments, structural effects, or both, and may shift substantially with lighting, age, and wear.

Feathers have long been used in art and ornament, but possession and trade may be regulated, particularly for protected native species. Do not assume this specimen is legally unrestricted without identifying its source.

Photograph both sides beside a ruler and record where it was found; compare the rachis, vane asymmetry, and any hidden bars or markings. Avoid collecting feathers where local wildlife laws prohibit it.

Appears intact overall, though the margins may be mildly worn or frayed; condition grade: Good. No clear fault bars, parasites, or oil contamination are visible.
