Description

A magnificent large owl with prominent ear tufts and yellow eyes. The feather reflects the bird's stealthy nature, featuring a soft surface that dampens sound. The Great Horned Owl is a powerful predator with a wingspan of up to 5 feet.

Colour & Pattern

Mottled brown, tan, and creamy white; features 5-6 broad dark brown transverse bands against a buffy-ochre background; the ventral side is paler than the dorsal side

Barb Structure

Pennaceous upper section with specialized velvet-like pile (flutulaceous surface) and plumulaceous downy base; features a 'comb-like' leading edge (fimbriae) for silent flight

Texture & Surface

Extremely soft and velvety to the touch (the 'muffle' effect); matte finish with no iridescence; leading edge feels slightly serrated

Key Features

Broad dark banding, velvety surface texture (hirsute), and the 'fringed' trailing edge typical of nocturnal predators

Habitat

Highly adaptable: found in deciduous and evergreen forests, swamps, deserts, subalpine fields, and urban parks/orchards

Geographic Range

Year-round resident across most of North America (from the subarctic to Mexico), Central America, and South America

Ecological Role

Apex nocturnal predator; controls populations of rodents, rabbits, and other birds; long-lived and sensitive to environmental toxins

Similar Species

Long-eared Owl (smaller, different banding frequency) and Barred Owl (shorter bands, more grayish-brown rather than ochre/buff)

Interesting Facts

Great Horned Owls can exert over 300 pounds per square inch of pressure with their talons and are one of the few predators that regularly hunt skunks

Condition Notes

Fair to Good; shows significant mechanical wear on the barbs and some separation of the vane (splits), likely a naturally molted feather from an older bird
