Description

The Great Horned Owl is a powerful, heavily built apex predator of the night, easily recognized by its prominent ear tufts, bright yellow eyes, and deep hooting call. It possesses exceptional eyesight and hearing, allowing it to ambush a wide variety of prey.

Colour & Pattern

Striking barred pattern featuring alternating dark brown/charcoal bands and buff/cream-colored bands on a grayish-white background. The base is soft grayish down.

Barb Structure

A mix of pennaceous structure near the tip and heavily plumulaceous (downy) structure near the base and along the edges. The barbs lack typical hooklets in the fluffy regions, creating a soft, sound-dampening velvet texture.

Texture & Surface

Extremely soft, velvety, and matte in appearance. The lack of rigid interlocking barbicels on the edges gives the feather a silent, noiseless quality critical for owl flight.

Key Features

Distinctive bold dark brown and buff barring on a mottled gray and white background, combined with a remarkably soft, downy texture along the edges for silent flight.

Habitat

Incredibly adaptable, found in deciduous, coniferous, and mixed forests, deserts, wetlands, swamps, agricultural areas, and urban parks.

Geographic Range

Widespread across North America, Central America, and South America, ranging from the subarctic down to Argentina. Year-round resident throughout its range.

Ecological Role

Acts as a top nocturnal apex predator controlling rodent, rabbit, and pest populations, serving as an important indicator of ecosystem health.

Similar Species

Barred Owl (Strix varia) and Long-eared Owl (Asio otus), but Barred Owls feature more longitudinal streaks on their breast feathers rather than horizontal barring.

Interesting Facts

Great Horned Owls are capable of exerting up to 500 pounds per square inch of pressure with their talons, roughly equivalent to a large dog's bite force.

Condition Notes

Good condition with some slight fraying along the plumulaceous barbs, likely due to water exposure and drifting along a stream.

Notes

Along a Stillwater/ stream, floating down from a pine tree by the water
