Large Avian Primary Flight Feather

This is a single primary flight feather from a large bird, likely of the accipitrid family, such as a large hawk or eagle. The feather measures approximately 10 to 12 inches in length. It features a robust, opaque white calamus (quill) and rachis, which provides significant structural integrity. The vane is asymmetrical, characteristic of primary flight feathers, with a dark slate gray to brownish-black coloration that transitions into a lighter, silvery-gray hue towards the base. At the proximal end of the rachis, there is a visible amount of white downy barbs (semi-plumes) which serve as insulation for the bird. The feather appears to be in relatively stable condition, though it shows some minor splitting and ruffling along the distal edges (fraying), which is common in naturally shed feathers. There are no signs of artificial dyes, treatments, or commercial manufacturing labels, suggesting it is a biological specimen rather than a decorative craft item. Of significant note is the legal status: if this specimen is determined to be from a migratory bird or a protected bird of prey (like a Bald or Golden Eagle), possession may be regulated or prohibited under the Migratory Bird Treaty Act or the Bald and Golden Eagle Protection Act.
