Description
A thick, soft contour feather from one of the world's most adaptable predators. The Great Horned Owl is a large bird with prominent ear tufts, yellow eyes, and a powerful silhouette. These feathers provide exceptional insulation for winter hunting.
Colour & Pattern
Muted greyish-buff base with distinct, soft-edged horizontal barring in dusky brown and warm ochre; light-colored intervals are creamy white to pale grey.
Barb Structure
Densely plumulaceous (downy) at the base with soft, velvety pennaceous barbs at the tip; lack of stiff interlocking barbicels creates the silent flight characteristic of owls.
Texture & Surface
Extremely soft, velvety, and 'muffled' to the touch; matte finish with a characteristic 'fringe' of fine pili (hairs) along the surface to dampen sound.
Key Features
Soft, blurred brown/buff horizontal bars (vermiculations) and an exceptionally large, fluffy downy base (plumulaceous section) distinctive of the Strigidae family.
Habitat
Extremely versatile, including hardwood forests, swamps, deserts, urban parks, and coniferous woodlands; prefers areas with high perches.
Geographic Range
Found throughout North and South America, from the Arctic tree line to the southernmost tip of South America; largely non-migratory.
Ecological Role
Apex predator; controls populations of rodents, rabbits, and even other birds of prey; occupies the highest trophic level in many ecosystems.
Similar Species
Barred Owl (Strix varia) feathers have more distinct, darker brown bars; Long-eared Owl (Asio otus) feathers are smaller and typically more orange/rufous.
Interesting Facts
Great Horned Owls can apply up to 28 pounds of pressure with their talons and are one of the few predators that regularly hunt skunks due to their poor sense of smell.
Condition Notes
Good; showing some mechanical fraying at the distal tip and slight separation of barbs from handling, likely a naturally molted specimen.
