Barb Structure
Tightly interlocked pennaceous structure with well-developed barbicels and hooklets, creating a strong, wind-resistant surface
Rachis & Barb Pattern
Strong, thick central white rachis with high-density barbs branching evenly at a consistent angle, providing structural rigidity for flight
Texture & Surface

North America, ranging from Alaska and Canada through the contiguous United States to northern Mexico
Ecological Role
Apex predator helping maintain balanced aquatic and terrestrial ecosystems by preying on fish, waterfowl, and scavenging carrion
