Description
This feather belongs to the Great Horned Owl, a massive predator known for its 'ear' tufts and yellow eyes. The bird has a wingspan of up to 5 feet and a bulky, mottled brown body designed for camouflage.
Colour & Pattern
Bold horizontal banding (barring) of dark umber brown against a buffy or mottled tan background. The tip features a dark terminal band with a slight white/buff edging.
Barb Structure
Pennaceous for the top two-thirds; plumulaceous (downy) at the base for insulation. Notably, the barbs have a velvety 'fringe' or pile that aids in silent flight, a hallmark of Strigiformes.
Texture & Surface
Extremely soft and velvety to the touch. The surface has a matte appearance with 'fimbriae' (hairs) that break up air turbulence to eliminate sound.
Key Features
Bold, regular dark brown barring on a buff background; velvety texture (silent flight adaptation); wide, rounded rectrix shape.
Habitat
Highly adaptable; found in deciduous and evergreen forests, swamps, desert scrub, parks, and suburban areas near lakes or open hunting grounds.
Geographic Range
Year-round resident across most of North and South America, from the subarctic tundra of Canada to the southern tip of Argentina.
Ecological Role
Apex nocturnal predator. They control populations of rodents, skunks, and even other birds of prey. Their presence indicates a healthy local food web.
Similar Species
Long-eared Owl feathers are similar but smaller and narrower. Barred Owl feathers have more uniform, grayish-brown barring without the rich buff/orange tones seen here.
Interesting Facts
Great Horned Owls have a crushing grip of 300-500 psi, strong enough to break the spine of a large rabbit or even a skunk—one of their favorite prey items.
Condition Notes
Fair to Good. The feather shows some wear and separation at the plumulaceous base; the rachis is intact, suggesting a natural molt rather than a predator strike.
Notes
In bend or near food and near a lake
