Description
A massive, powerful raptor with a wingspan reaching over 7 feet. Adults are dark brown with golden-tipped feathers on the nape, while immatures show distinct white patches on wings and tail.
Colour & Pattern
Dark chocolate brown base with characteristic pale tawny or whitish mottling and marbling toward the base and center of the vane; typical of immature or sub-adult plumage.
Barb Structure
Tightly interlocked pennaceous barbs providing a rigid and aerodynamic surface; robust barbules with strong hooklets for flight integrity.
Rachis & Barb Pattern
The rachis is thick, sturdy, and dark brown to black on the dorsal side; barbs are densely packed and emerge at an acute angle to provide maximum lift.
Texture & Surface
Stiff, smooth, and slightly glossy on the upper surface; the underside has a more matte, silvery-brown appearance.
Feather Placement
Wing; the asymmetry and size suggest it is a secondary feather or a mid-primary from the wing of a large raptor.
Key Features
Large size, dark brown coloration with distinct irregular pale mottling at the base of the barbs, and a very thick, rigid central rachis.
Habitat
Open and semi-open country, mountains, plateaus, and cliffs; avoids heavily forested areas in favor of wide-ranging hunting grounds.
Geographic Range
Widespread across the Northern Hemisphere, including North America, Eurasia, and parts of North Africa; mostly resident in mountainous regions.
Ecological Role
Apex predator; controls populations of small to medium mammals like jackrabbits and marmots; sensitive indicator of terrestrial ecosystem health.
Similar Species
Bald Eagle (immature feathers lack the specific tawny marbling and often show more extensive, blotchy white), Turkey Vulture (feathers are lighter, more uniform brownish-grey).
Interesting Facts
Golden Eagles are capable of taking down prey as large as deer and are known for their incredible diving speeds, which can exceed 150 miles per second.
Cultural Significance
Highly sacred in many Native American cultures, symbolizing courage and strength; feathers are used in traditional headdresses and ceremonies.
Field Identification Tips
Look for these in mountainous or hilly terrain near cliff faces or high-elevation meadows, especially during late summer molting periods.
Condition Notes
Fair to Good; shows significant wear and fraying at the tips (apical tattering), suggesting it was molted after a full season of use.
