Likely White-tailed Kite; also called Black-shouldered Kite in some regions. Identification is tentative from one feather.

The specimen is a dark, white-tipped feather consistent with a kite or another bird bearing contrasting pale feather tips. White-tailed Kites are elegant, pale raptors with black shoulder patches, long wings, and a characteristic hovering hunt over open fields.

Mostly dark brown to black with a sharply contrasting white terminal patch. The visible surface shows no clear barring; lighting may alter the apparent brown tone.

The vanes appear tightly interlocked and pennaceous. Fine barb condition and any aftershaft are not clearly visible.

A slender, dark central rachis runs through the feather; dark barbs form most of the vane, ending abruptly at the pale tip.

Smooth, compact, and relatively stiff-looking, with a subdued sheen; surface condition is difficult to assess in this lighting.

Probably from the wing, inferred from its long, firm shape; a tail feather cannot be excluded.

The abrupt white terminal area against a dark vane is the clearest visible feature, but it is not unique enough for a secure species identification.

White-tailed Kites hunt open grasslands, agricultural fields, marsh edges, and other open country, often nesting in trees near foraging grounds.

Occurs in the Americas, especially western and southern North America and parts of Central and South America; populations vary in residency and local movements.

White-tailed Kites are rodent predators and can reflect the health of open-country ecosystems. This feather alone cannot establish species or conservation status.

Other kites and raptors, as well as some corvids, can have dark feathers with pale tips. A full set of feathers, exact measurements, and location would be needed to compare reliably.

White-tailed Kites often hover in place while scanning for rodents, a hunting behavior known as kiting.

Raptor feathers may be subject to wildlife-protection laws; possession and trade can be restricted. Do not collect or sell wild feathers without checking local regulations.

Record the find location and measure the feather; compare it with regional feather guides, paying attention to vane asymmetry, shaft color, and pattern across the entire feather.

Appears largely intact with no obvious major breakage; wear, molt stage, and fine damage cannot be judged from this view.
