Description

This feather belongs to the Great Horned Owl, a massive, powerful raptor known for its prominent ear tufts and piercing yellow eyes. The bird has a bulky barrel-shaped body and a wingspan of up to 5 feet. Its plumage provides perfect camouflage against tree bark.

Colour & Pattern

Mottled ochre, cream, and tawny-buff base. It features dark brown horizontal bars (banding) that are somewhat irregular or 'toothed'. The ventral (underside) is lighter and more muted than the dorsal side.

Barb Structure

The barbs are pennaceous but feature a specialized velvet-like pile (diurnal owl adaptation). The leading edge has 'comb-like' serrations (fimbriae) to break up airflow for silent flight.

Texture & Surface

Extremely soft, silky, and 'fuzzy' to the touch. This velvety texture is a structural adaptation that muffles the sound of air passing over the wing.

Key Features

Soft velvet-like surface pile, rounded tip, distinct dark brown barring on a buff/ochre background, and 'silent flight' serrations on the leading edge.

Habitat

Highly adaptable: found in deciduous and evergreen forests, swamps, deserts, tundra edges, orchards, and urban parks.

Geographic Range

Found throughout North and South America, from the subarctic northern tree line to the southern tip of South America. Non-migratory/Resident.

Ecological Role

Apex predator; keeps rodent, rabbit, and smaller bird populations in check. They are considered an ecological 'top-down' regulator.

Similar Species

Barred Owl (Strix varia) feathers are similar but generally show more regular, clean-edged horizontal banding and lack the deep ochre/orange tones of the Great Horned Owl.

Interesting Facts

Great Horned Owls have no sense of smell; they are one of the few animals that regularly prey on skunks. Their grip can exert over 300 pounds per square inch.

Condition Notes

Fair to Good. There is some minor separation of the barbs near the tip and fraying at the calamus (base), suggesting it is a naturally molted feather found on the ground.
