Description
A medium-sized body feather from the Great Horned Owl, a powerful predator known for its 'horns' (ear tufts). The bird has deep yellow eyes, a white throat patch, and a variegated plumage of browns, greys, and blacks that mimic tree bark. They are apex nocturnal hunters with a wingspan of up to 5 feet.
Colour & Pattern
Mottled grey-brown at the distal end transitioning to a creamy-white or pale buff base. Features fine horizontal vermiculations (wavy lines) typical of owl camouflage.
Barb Structure
Highly plumulaceous (downy) at the base with a soft pennaceous tip; features specialized velvet-like barbules designed to muffle sound during flight.
Texture & Surface
Extremely soft, silky, and velvet-like. It has a matte finish with no iridescence, primarily specialized for sound dampening and insulation.
Key Features
The presence of fine, hair-like fringes (fimbriae) on the barbs and the distinctive grey-mottled tip over a pale downy base are diagnostic for Strigidae body feathers.
Habitat
Highly adaptable; found in deciduous and evergreen forests, swamps, deserts, subalpine heights, and urban parks.
Geographic Range
Year-round resident throughout North and South America, from the northern tree line in Alaska and Canada to the southern tip of South America.
Ecological Role
Apex predator; controls populations of rodents, rabbits, and even other birds of prey. They are critical indicators of local ecosystem health.
Similar Species
Long-eared Owl feathers (narrower, more orange tones) and Barred Owl feathers (starker horizontal banding, less mottled).
Interesting Facts
Great Horned Owls can apply up to 28 pounds of pressure with their talons. They are one of the few animals that regularly hunt skunks, as they have a very poor sense of smell.
Condition Notes
Fair to Good. The feather shows some compression and tangling of the plumulaceous barbs, likely due to contact with moisture or handling, but the rachis remains intact.
