Colour & Pattern
Intricate barred pattern with alternating dark brown, tawny, and white or buff chevron markings, typical of melanin-based pigmentation providing cryptic camouflage
Barb Structure
Mixed structure with a stiff, pennaceous distal tip featuring interlocked barbs and a loose, plumulaceous proximal base; prominent downy afterfeather
Texture & Surface
Soft and velvety texture overall with a stiffer tip; specialized velvet-like micro-structure on the barbs designed for silent flight

Geographic Range
Widespread across North, Central, and South America, ranging from the subarctic tree line down to South America as a year-round resident
Ecological Role
Apex nocturnal raptor that plays a crucial role in controlling populations of rodents, rabbits, and other small to medium-sized mammals
Similar Species
Barred Owl (Strix varia) and Short-eared Owl (Asio flammeus), distinguished by different barring widths and color tones
Interesting Facts
Great Horned Owls can exert a crushing force of over 300 pounds per square inch with their talons, and they are primary nest usurpers, often taking over abandoned hawk or eagle nests
Condition Notes
Fair condition with some wear and slight fraying along the edges of the plumulaceous barbs, but structural integrity is intact
