Description
This feather is a quintessential example of the silent flight adaptations of the Great Horned Owl. The bird itself is a powerful predator, 46–63 cm long with a wingspan up to 145 cm, characterized by prominent ear tufts and a deep hooting call.
Colour & Pattern
Alternating wide bands of dark chocolate brown or charcoal and warm ochre, buff, or tawny orange; upper bands show dense dark mottling/stippling.
Barb Structure
Specialized pennaceous structure with long, hair-like barbules (fimbriae) creating a velvety texture; trailing edge exhibits a soft fringe.
Texture & Surface
Extremely soft, silky, and matte; the surface is covered in a 'velvety pile' that dampens sound during flight.
Key Features
Distinctive velvety surface texture, soft trailing edge fringe (fimbriae), and bold tawny and dark brown banding with fine stippling.
Habitat
Extremely adaptable species found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and urban parks.
Geographic Range
Resident throughout North America from the Arctic tree line south through Central and South America.
Ecological Role
Apex nocturnal predator; controls populations of rodents, rabbits, and even other birds of prey.
Similar Species
Long-eared Owl feathers (smaller, narrower), Barred Owl feathers (more grey-brown tones, lacks the intense tawny/orange hue).
Interesting Facts
The Great Horned Owl's feathers are so well-adapted for silence that they can fly within inches of prey without being heard; they have one of the most diverse diets of any North American raptor.
Condition Notes
Good condition; slight mechanical wear (splitting) visible near the margin, typical of naturally molted feathers or handled specimens.
