Description
A magnificent large owl with prominent ear tufts and a white throat bib. This feather showcases the intricate camouflage that allows the owl to vanish against tree bark during the day. Their silent flight is enabled by the specialized soft edges seen on this specimen.
Colour & Pattern
Mottled and barred with dark umber brown, buffy-orange, and grayish-white. Strong horizontal banding (barring) interspersed with fine vermiculation (worm-like markings).
Barb Structure
Pennaceous distal portion with a velutinous (velvety) surface; plumulaceous (downy) base. Features a soft, fringed leading edge (fimbriae) to break up airflow.
Texture & Surface
Extremely soft, silky, and matte. The dorsal surface has a fine pile or 'fuzz' that dampens sound, while the ventral surface is smooth and slightly glossy.
Key Features
Heavy dark barring combined with fine gray vermiculation; velvet-like texture; soft 'fimbriae' on the edges; buff-orange wash at the base/inner vane.
Habitat
Highly adaptable: found in deciduous and evergreen forests, swamps, orchards, agricultural areas, and even suburban parks or desert canyons.
Geographic Range
Common year-round resident across North and South America, ranging from the Arctic treeline south to the Straits of Magellan.
Ecological Role
Apex predator; controls populations of rodents, rabbits, and even other birds of prey. Considered a top-tier indicator of ecosystem health.
Similar Species
Long-eared Owl feathers are similar but smaller and more slender. Barred Owl feathers lack the warm buff/orange tones and have more distinct, crisp white-and-brown barring.
Interesting Facts
Great Horned Owls have a crushing power in their talons of up to 500 psi. They are one of the few predators that regularly hunt skunks because they have a poor sense of smell.
Condition Notes
Good; shows some minor ruffling at the tip and separation of the barbs near the base, likely a naturally molted feather from a healthy adult.
