Description
The Bald Eagle is a magnificent bird of prey with a dark brown body, distinctive white head and tail, and bright yellow beak and feet. Adults can have a wingspan reaching up to 7 feet. Their flight is powerful and steady, often soaring on flat wings.
Colour & Pattern
Stunning stark contrast featuring a solid dark black-brown upper tip transitioning gracefully into a mottled grayish-brown midsection and a clean, brilliant white base near the calamus, with a robust white-to-yellowish rachis
Barb Structure
Strongly pennaceous with tightly interlocked barbs and barbicels, creating a smooth, durable surface designed for aerodynamic efficiency
Texture & Surface
Stiff, smooth, and rigid with a semi-glossy finish on the dorsal side and a more matte finish on the ventral side
Key Features
Large size, striking color gradient from deep black-brown to pure white at the base, strong asymmetry, and a stout white rachis
Habitat
Found near large bodies of open water with an abundant food supply and old-growth trees for nesting, including lakes, reservoirs, rivers, coasts, and marshes
Geographic Range
North America, ranging from Alaska and Canada down through the United States and into northern Mexico
Ecological Role
Apex predator helping to maintain healthy fish and small mammal populations, serving as a key indicator of aquatic ecosystem health
Similar Species
Golden Eagle (Aquila chrysaetos), whose large dark flight feathers typically lack the distinct bright white base found on many adult Bald Eagle feathers
Interesting Facts
Bald Eagles can dive for fish at speeds up to 100 miles per hour and build the largest nests of any North American bird, sometimes weighing over a ton
Condition Notes
Good condition with intact barbs and minimal fraying, showing a naturally molted adult flight feather
