Scarlet Macaw (alternate: Red-and-yellow Macaw)

A long, tapered primary feather from one of the world's most iconic parrots. The Scarlet Macaw is a large, brilliantly colored bird reaching nearly 3 feet in length (including tail). It features scarlet red plumage on most of the body, with yellow wing coverts and blue flight feathers. This yellow feather represents the bright wing band that distinguishes it from the Green-winged Macaw.

Uniform vibrant golden-yellow to rich orange-yellow on the dorsal surface. The color is structural and melanin-based. No banding or spots are present. The ventral side is a slightly more matte version of the same hue.

Tightly interlocked pennaceous barbs with well-developed barbicels forming a stiff, wind-resistant surface suitable for powerful flight. The base shows minimal plumulaceous down.

The rachis is thick, sturdy, and light tan to yellowish in color. It exhibits a distinct lateral curvature. Barbs are densely packed, angled toward the tip to maximize aerodynamical efficiency.

Smooth, stiff, and glossy. The surface feels somewhat waxy or oily, providing minor water resistance. The leading edge is extremely rigid compared to the more flexible trailing vane.

Outer wing (Primary). The extreme asymmetry and curvature indicate it is one of the outermost flight feathers used for propulsion and lift.

Pure, unbanded yellow/orange coloration, extreme primary asymmetry, and large size typical of the genus Ara.

Humid lowland subtropical and tropical rainforests, open woodlands, and river edges.

Southeastern Mexico to Amazonian Peru, Bolivia, and Brazil. They are largely non-migratory but may move locally following food sources.

Large-seed predator and disperser. They play a vital role in forest regeneration by carrying seeds away from parent trees. Listed as 'Least Concern' globally by IUCN, but many local populations are 'Critically Endangered'.

Blue-and-yellow Macaw (Ara ararauna) feathers are similar but often show more lime-green/yellow and different curvature; Green-winged Macaw (Ara chloropterus) primaries are deep blue, not yellow.

Scarlet Macaws are highly intelligent and can live up to 50–75 years. They use their powerful beaks as a 'third foot' while climbing through the rainforest canopy.

Historically used by Mesoamerican and South American indigenous cultures in ceremonial headdresses and regalia. They were traded extensively across the Americas for centuries.

In their native range, look under large fruiting trees (like Almond or Dipteryx) or near clay licks during the molting season (post-breeding).

Excellent condition. The vanes are tightly closed with no visible fault bars or parasitic wear. This appears to be a freshly molted feather.
