Description
A large, powerful owl with prominent ear tufts and yellow eyes. The feather reflects the bird's cryptic camouflage designed to blend into tree bark
Colour & Pattern
Alternating fine horizontal vermiculations (wavy lines) of dusky brown or grayish-black on a cream to buff-white background
Barb Structure
Velvety and plumulaceous; features high densities of micro-pennulum (barbule extensions) creating a soft, sound-dampening surface
Texture & Surface
Velvety, soft, and matte. The surface is designed to minimize friction and air turbulence, and lacks the glossy finish of waterfowl feathers
Key Features
Distinctive 'salt and pepper' vermiculation pattern and a soft, velvety texture that is unique to the silent-flight adaptations of owls
Habitat
Extremely adaptable; found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and urban parks with large trees
Geographic Range
Resident across most of North America from the subarctic to Central and South America; generally non-migratory
Ecological Role
Apex nocturnal predator; controls populations of rodents, rabbits, and even other birds of prey. Essential for rodent control in many ecosystems
Similar Species
Barred Owl feathers (Strix varia) which have thicker, more distinct horizontal bars rather than fine vermiculations
Interesting Facts
Great Horned Owls have a crushing power in their talons of up to 500 psi; they are one of the few predators that regularly hunt skunks
Condition Notes
Fair to Good; shows significant wear at the distal tip with some separation of the barbs (vane splitting) likely due to environmental exposure
