Description
This feather belongs to a large, imposing owl with prominent 'ear tufts.' The Great Horned Owl is known for its deep 'hoo-h'hoo-hoo-hoo' call and yellow eyes. This specific feather provides the owl with its characteristic nocturnal camouflage, allowing it to blend perfectly with lichen and bark while perched.
Colour & Pattern
Striking transverse barring and mottling. Base colors are dark soot-brown to black, intercepted by buff-orange, cream, and grayish-white vermiculations. The patterning mimics tree bark.
Barb Structure
The distal portion is pennaceous but exceptionally soft; the proximal base is plumulaceous (downy). Includes a velvety 'pile' on the surface and 'fimbriae' (fringes) on the edges to dampen sound.
Texture & Surface
Textbook 'velvety' or silken texture. The surface lacks the glossy sheen found in waterbirds, appearing matte to absorb light and sound.
Key Features
Soft fringed edges (fimbriae), velvety surface pile for silent flight, and complex 'bark-like' mottled barring of soot and buff colors.
Habitat
Extremely versatile: found in deciduous and coniferous forests, deserts, mountain cliffs, urban parks, and suburban woodlots.
Geographic Range
Found throughout North America from the Arctic tree line south to Central and South America. Non-migratory and highly adaptable.
Ecological Role
Apex nocturnal predator. They control populations of rodents, skunks, and even other birds of prey. They are vital indicators of ecosystem health.
Similar Species
Long-eared Owl (smaller, more linear feathers), Barred Owl (more defined 'cold' gray barring without the warm buff tones), and Great Gray Owl (larger, more uniform gray).
Interesting Facts
Great Horned Owls are one of the only consistent predators of skunks because they have a very poor sense of smell. They also have a grip strength of up to 500 PSI, comparable to a much larger Golden Eagle.
Condition Notes
Fair to Good. There is significant separation of the barbs (venting) near the mid-section, and the downy base is somewhat matted, suggesting it may have been exposed to the elements after molting.
