Description

A magnificent large raptor feather featuring the classic dark brown-to-black coloration contrasting with a bright white base, typical of sub-adult or mature Bald Eagle plumage. The Bald Eagle itself is a massive sea eagle with a commanding wingspan, dark body, and unmistakable stark white head and tail in adulthood.

Colour & Pattern

Rich dark charcoal-grey to blackish-brown upper vane transitioning smoothly into a lighter brownish-grey midsection and a contrasting pristine white base near the calamus.

Barb Structure

Strongly pennaceous through the upper vane with tightly interlocked barbs and barbicels forming a solid, wind-resistant surface; semiplumulaceous at the extreme base.

Texture & Surface

Stiff, smooth, and durable with a semi-glossy finish on the dorsal surface, designed to withstand high friction and wind resistance during flight.

Key Features

Strong white calamus and rachis extending into a dark brownish-black pennaceous vane with a stark white basal section.

Habitat

Found near large bodies of open water with old-growth trees for nesting, including lakes, reservoirs, rivers, coasts, and marshes.

Geographic Range

North America, ranging from Alaska and Canada down through the contiguous United States to northern Mexico.

Ecological Role

Apex avian predator playing a vital role in maintaining aquatic and coastal ecosystem health by removing sick or dead fish and waterfowl.

Similar Species

Golden Eagle (Aquila chrysaetos), whose feathers lack the stark white base and are generally uniformly dark brown or golden-brown throughout.

Interesting Facts

Bald Eagles build the largest nests of any North American bird, sometimes weighing over two tons and used for decades.

Condition Notes

Good condition with minor wear along the edges, intact rachis, and no major structural damage or fault bars.
