Description

A striking large raptor feather showing a distinct contrast between dark grey downy fluff and stark white tip plating, reflective of the majestic Bald Eagle's iconic contrasting adult plumage

Colour & Pattern

Bicolored appearance featuring a contrasting dark grayish-brown lower/proximal section and a clean white upper/distal section, typical of transitional body plumage or immature development

Barb Structure

Plumulaceous (downy) and semiplume structure, featuring loose barbs without tightly interlocked barbicels near the base, transitioning to a more compressed structure along the shaft

Texture & Surface

Soft, fluffy, and silky texture with high insulating properties and a matte, non-glossy finish

Key Features

Distinctive two-tone color break (dark grey transitioning abruptly to white), soft downy structure at the base, and large scale indicative of a premier apex avian predator

Habitat

Found near large bodies of open water with old-growth trees for nesting and an abundant food supply, such as lakes, rivers, coasts, and marshes

Geographic Range

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

Ecological Role

Apex predator helping to maintain the health and balance of aquatic and terrestrial ecosystems by preying primarily on fish, waterfowl, and carrion

Similar Species

Golden Eagle (Aquila chrysaetos), which lacks the clean white plumage transition and typically shows more uniform brownish or barred golden tones

Interesting Facts

Bald Eagles build the largest tree nests ever recorded for any animal species, some weighing over two tons and being used and added to for decades

Condition Notes

Good condition overall with intact barbs and a well-preserved rachis, showing minor natural wear consistent with molted body plumage
