Likely Golden Eagle (also called the Golden Eagle)

This is a substantial two-toned flight feather with a striking yellow-looking shaft. Golden Eagles are large, dark-brown raptors with golden nape feathers, broad wings, and soaring flight; the feather alone does not establish that species.

Cream to pale buff inner vane, dark brown outer vane, and a pale shaft that appears vivid yellow—possibly naturally colored, dyed, or artificially enhanced. Broad pale patches cross the dark area; lighting and the visible face limit interpretation.

Pennaceous vanes with interlocking barbules; several barbs along the dark edge appear separated or frayed. No aftershaft is clearly visible.

The long, slender rachis is bright yellow and contrasts strongly with the dark brown barbs on one side and pale barbs on the other; this unusual appearance warrants caution about alteration.

Mostly smooth, flat, and firm, with loose, ragged barbs along the darker edge; no clear gloss or powder is evident.

Probably from the wing, based on its elongated, asymmetrical form; a tail feather is less likely.

Strongly asymmetric vane, cream-and-dark-brown contrast, and unusually vivid yellow shaft. Color alteration or a non-eagle source cannot be excluded from the photograph.

If from a Golden Eagle, it would be associated with open mountains, cliffs, steppe, tundra, and other broad landscapes with nearby nesting ledges.

Golden Eagles occur across much of the Northern Hemisphere, including North America, Europe, and Asia; many northern birds migrate or move seasonally.

Golden Eagles are apex predators that help regulate prey populations; they depend on extensive open hunting habitat and undisturbed nesting sites. Population pressures vary regionally, with habitat change and collisions among notable risks.

Other large eagles and hawks can have dark, pale-banded flight feathers. A bright yellow rachis is not a reliable Golden Eagle field mark and may indicate dyeing or craft treatment.

Golden Eagles can soar for long periods on rising air and capture prey ranging from rabbits to large birds. Their broad wings and powerful feet suit both soaring and active hunting.

Eagle feathers have deep significance in many Indigenous cultures, and possession or trade may be legally restricted. Do not collect, buy, or transport this specimen without confirming its origin and applicable laws.

Photograph both sides, measure the feather, and record where it was found; compare with verified regional feather references or consult a qualified wildlife agency. Avoid handling or keeping suspected protected raptor feathers.

Barbs are visibly separated or ragged in places; overall condition appears fair. No definite fault bars, parasites, or oil contamination are visible.
