Colour & Pattern
Solid dark brownish-black transitioning sharply to clean, bright white at the base and inner web, indicating a tail or wing feather from an adult bird
Barb Structure
Pennaceous vane with tightly interlocked barbs and barbicels, firm and durable structure with some fraying visible at the base
Texture & Surface
Stiff, smooth, and matte finish with high structural rigidity to withstand strong aerodynamic forces during flight
Key Features
Large size, stiff asymmetrical vane, stark bi-colored pattern of dark brown and bright white, and robust white-to-dark rachis
Habitat
Found near large bodies of open water with an abundant food supply and old-growth trees for nesting, including lakes, reservoirs, rivers, and coastal marine areas

North America, ranging from Alaska and Canada down through the contiguous United States and into northern Mexico
Ecological Role
Apex avian predator at the top of the aquatic food web, playing a crucial role in maintaining healthy fish and waterfowl populations
Similar Species
Golden Eagle (Aquila chrysaetos), which lacks the clean stark white bases on primary flight feathers and has more uniformly brown or barred patterns
