Likely Turkey Vulture; possibly another large vulture or eagle

This is a large dark flight feather typical in general form of a Turkey Vulture, a long-winged scavenger with a small red, bare head and a broad wingspan around 1.7–1.8 m (5.5–6 ft). In flight, Turkey Vultures soar with wings in a shallow V and frequently rock from side to side.

Uniform dark brown to charcoal-brown overall, with subtle warm brown highlights and no obvious banding or spots. The rachis is pale gray-beige; lighting and wear may alter the apparent tone.

Pennaceous and relatively stiff over most of the vane, with a loose, downy aftershaft and frayed basal barbs.

Straight, slender pale rachis with dense, smooth barbs distally and increasingly sparse, fluffy barbs toward the base; the vanes are unequal in width.

Smooth, matte-to-slightly glossy and fairly rigid distally, becoming soft and downy at the base; no obvious iridescence or oil contamination.

Likely the outer wing, inferred from its asymmetry, length, and rigid vane; exact primary/secondary position cannot be confirmed from this view.

Large asymmetrical dark-brown remex, pale rachis, and conspicuously fluffy basal aftershaft. Species-level identification from one isolated feather remains tentative.

Turkey Vultures occupy open country, woodland edges, deserts, farmland, roadsides, and coastlines, roosting communally in trees, cliffs, and structures.

Widespread from southern Canada through the United States, Mexico, Central America, and much of South America; northern populations migrate seasonally.

A major scavenger that rapidly removes carrion and helps limit disease spread; populations are generally stable or increasing, though they face risks from collisions, poisoning, and habitat disturbance.

Black Vulture feathers are generally darker and more compact; large eagle feathers are stiffer and often show stronger patterning or broader vanes. Turkey Vulture primaries commonly have paler silvery-gray undersides, not evident here.

Turkey Vultures locate carrion largely by smell, an unusual ability among birds; their soaring flight conserves energy while searching broad territories.

Vulture feathers have been used historically in art, regalia, and craftwork, but possession and transport of native North American bird feathers may be regulated under the Migratory Bird Treaty Act.

Compare several feathers together, especially the underside and wing pattern; search beneath communal roosts and along wooded edges. Photograph with a ruler and avoid disturbing active nests or roosts.

Apparently naturally molted and moderately worn, with broken/frayed basal barbs but an intact distal vane; no clear fault bars or parasites visible. Condition: Good.
