Description

The Great Horned Owl is a powerful, heavily built nocturnal predator characterized by prominent ear tufts, bright yellow eyes, and a deep, booming hoot. Its plumage is a masterpiece of cryptic coloration, perfectly blending into tree bark.

Colour & Pattern

Intricate barred pattern with alternating light grey-brown (buff) and dark brown transverse bands against a white and pale grey background, typical of cryptic camouflage plumage.

Barb Structure

Pennaceous at the distal tip transitioning into an extensive plumulaceous (fluffy) base with loose, separated barbs lacking functional interlocking barbicels near the skin insertion.

Texture & Surface

Exceptionally soft, velvety, and matte in texture, lacking any glossy sheen, specifically adapted to muffle sound during flight.

Key Features

Distinctive bold horizontal barring of dark brown and buff on a pale background, combined with an exceptionally soft, downy basal half typical of large owl contour feathers.

Habitat

Extremely adaptable, inhabiting deciduous, coniferous, and mixed forests, deserts, wetlands, agricultural areas, and urban parks.

Geographic Range

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

Ecological Role

Apex nocturnal raptor that plays a crucial role in controlling populations of rodents, rabbits, and other small mammals.

Similar Species

Barred Owl (Strix varia) and Short-eared Owl (Asio flammeus), distinguished by finer streaking rather than bold transverse barring.

Interesting Facts

Great Horned Owls are capable of exerting up to 500 pounds of pressure per square inch in their grip, comparable to the bite force of a large dog.

Condition Notes

Good condition, showing minor natural fraying at the extreme tip and intact barbs along the vane, suggesting it was naturally molted.
