Description

The Great Horned Owl is a powerful, heavily built nocturnal predator featuring prominent ear tufts, intense yellow eyes, and a deep, resonating hooting call. This feather exhibits the classic camouflage patterns and specialized velvety texture characteristic of nocturnal raptors.

Colour & Pattern

Mottled earthy brown, grayish-buff, and dark brown barring across the distal vane, blending into a pale, downy white base proximal to the quill.

Barb Structure

Plumulaceous (soft and loose) toward the base with specialized velvety fringes and lack of rigid barbicels near the tips, ensuring silent flight. Condition is intact.

Texture & Surface

Extremely soft, velvety, and matte in texture with no gloss, designed specifically for acoustically silent flight.

Key Features

Soft velvety edges (fringes), pale downy base, and bold brown and buff barring patterns characteristic of owl body contour feathers.

Habitat

Incredibly adaptable, inhabiting forests, deserts, wetlands, urban areas, tundra edges, and agricultural lands.

Geographic Range

Widespread across the Americas, ranging from the subarctic regions of Canada and Alaska down through the United States, Central America, and deep into South America.

Ecological Role

Apex nocturnal avian predator playing a vital role in regulating rodent and small mammal populations across diverse ecosystems.

Similar Species

Barred Owl (Strix varia) and Short-eared Owl (Asio flammeus), distinguished by differing bar widths and overall color tones.

Interesting Facts

Great Horned Owls are capable of exerting a crushing foot pressure of over 500 pounds per square inch, roughly equivalent to that of a large-to-medium canine's jaw.

Condition Notes

Good condition with minor wear at the apex of the vane, fully intact structure, no visible fault bars or parasitic damage.
