Uncertain; possibly a yellow-headed blackbird or another blackbird with a yellow shoulder patch

This is a small, loose feather with a striking yellow tip, but the image does not show enough diagnostic detail to identify its source confidently. A yellow-headed blackbird is one possibility, though other birds or altered feathers could produce similar colors.

Gray-brown vane with a vivid yellow area at the tip and a darker patch just below it. Lighting and image resolution limit assessment of the true colors and any surface-side differences.

Pennaceous vane with barbs mostly aligned; some edges appear loose or worn. Fine barbules cannot be resolved in the image.

Pale, slender central rachis; barbs form a narrow vane, with apparent irregularity along the edges.

Appears smooth and matte, with some fraying; texture cannot be confirmed from a photograph.

Possibly a shoulder or wing-coverts feather, suggested by the compact shape and contrasting yellow tip; placement is uncertain.

Distinctive bright yellow terminal patch, gray-brown body, and narrow shape; these features alone are not species-diagnostic.

If from a yellow-headed blackbird, typical habitats are marshes and wetlands with emergent vegetation, with nearby grassland or agricultural feeding areas.

A yellow-headed blackbird would breed in western and central North America and winter mainly in the southern United States and Mexico; the feather itself does not establish the species.

If from a yellow-headed blackbird, it is an omnivore and wetland-nesting species that consumes seeds and insects and serves as prey for larger predators; wetland loss is an important conservation pressure.

Other icterid feathers and yellow-marked songbird feathers may look similar; a clear view of the entire bird or diagnostic wing pattern would be needed to distinguish them.

Yellow-headed blackbirds often nest colonially in marshes, and males display their bright yellow heads and white wing patches during courtship.

Feather trade and collecting laws vary by species and jurisdiction; many native wild-bird feathers are legally protected. Do not collect or possess uncertain wild feathers without checking local regulations.

Photograph both sides beside a ruler, keeping the feather flat and in neutral light; record where it was found. Avoid relying on color alone, and check local feather-possession laws.

Appears detached and slightly ragged at the edges; no clear evidence of active growth, parasites, or major breakage is visible. Condition: fair to good.
