Description
This is a large, powerful owl with prominent ear tufts and a white throat patch. They possess a 3-5 foot wingspan and are known for their deep, rhythmic hooting. The feather reflects their apex predator status, built for stealth and durability.
Colour & Pattern
Mottled brown, tan, and cream base with distinct dark brown to blackish horizontal barring. The ventral side is typically paler with more muted banding; the pattern provides excellent camouflage against tree bark.
Barb Structure
Pennaceous; featuring specialized distal barbules that create a soft, velvety 'fimbriate' fringe and a downy surface to muffle sound during flight.
Texture & Surface
Extremely soft and velvety to the touch. The surface has a matte appearance with a unique 'pilose' (hairy) texture that reduces air turbulence and ensures silent flight.
Key Features
Distinctive horizontal 'tiger' barring, soft downy texture for silent flight, and a robust, curved rachis characteristic of large owls.
Habitat
Highly adaptable; found in deciduous and evergreen forests, swamps, deserts, tundra edges, tropical rainforests, cities, and suburban parks.
Geographic Range
Year-round resident throughout North and South America, from the subarctic tree line in the north to the southern tip of South America.
Ecological Role
Apex predator; controls populations of rodents, rabbits, and even other birds of prey. They are highly sensitive to environmental toxins and serve as bioindicators.
Similar Species
Long-eared Owl feathers are smaller and more slender; Barred Owl feathers have more uniform, cleaner chocolate-brown bands without the heavy tan mottling.
Interesting Facts
Great Horned Owls have a crushing power in their talons of up to 500 lbs per square inch, and they are one of the few animals that regularly hunt skunks since they have a poor sense of smell.
Condition Notes
Fair to Poor; the specimen shows significant 'splitting' (separation of the barbs) and frayed edges, suggesting it may have been exposed to the elements or heavily used before molting.
