Description
The Bald Eagle is a large raptor easily recognized in adulthood by its iconic white head and tail contrasting with a dark brown body. Immature birds, which these feathers likely represent, are largely dark brown with variable white mottling underneath and on the body.
Colour & Pattern
Dark brownish-black tips and central webs with distinct white mottling and white base areas, characteristic of immature or subadult Bald Eagle plumage.
Barb Structure
Pennaceous at the upper portion with tightly interlocked barbs and barbicels, transitioning to a plumulaceous (fluffy) downy base.
Texture & Surface
Smooth and firm at the distal pennaceous tip, transitioning to soft and fluffy at the base.
Key Features
Distinctive dark brown and white mottled pattern, robust pale rachis, and the combination of pennaceous and plumulaceous barbs.
Habitat
Found near large bodies of open water with an abundant food supply and old-growth trees for nesting.
Geographic Range
North America, ranging from Alaska and Canada through the contiguous United States to Mexico.
Ecological Role
Apex predator helping to maintain healthy aquatic and terrestrial ecosystems.
Similar Species
Golden Eagle (Aquila chrysaetos), which features more uniform dark brown feathers without the characteristic white mottling found in immature Bald Eagles.
Interesting Facts
Bald Eagles can dive for fish at speeds up to 100 miles per hour and build the largest nest of any North American bird.
Condition Notes
Good condition with intact barbs and minimal fraying, showing natural color variations typical of a molted covert feather.
