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
