- Shape
- Broad and slightly asymmetrical with a rounded tip; the outline is somewhat spatulate with a consistent width through the midsection.
- Size

Description
This is a large tail feather from a Great Horned Owl, a powerful apex predator known for its 'horns' (ear tufts) and deep hoots. The bird itself is mottled gray-brown with a white throat patch and yellow eyes. This specific feather reflects the owl's camouflage—mimicking tree bark and dappled sunlight.
Colour & Pattern
Rich tawny-ochre or buffy base color with 4-5 bold, dark brown horizontal bars. The spacing between bars shows fine brown mottling or 'vermiculation'. The ventral (under) side is noticeably paler and more matte.
Barb Structure
Pennaceous structure with specialized velvet-like pile (fimbriae) on the dorsal surface and a soft, fringed trailing edge to facilitate silent flight. Plumulaceous (downy) barbs are present at the very base near the calamus.
Texture & Surface
Extremely soft and velvety to the touch ('silent' texture); the surface has a matte appearance with a distinct 'fluff' that breaks up airflow.
Key Features
Tawny/buff base color, bold dark brown banding, and a velvety 'hirsute' surface texture unique to owls for noise suppression.
Habitat
Highly adaptable: found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and even suburban parks.
Geographic Range
Extensive range across North and South America, from the subarctic treeline in Alaska and Canada to the southern tip of South America. Mostly non-migratory permanent residents.
Ecological Role
Apex predator; controls populations of rodents, rabbits, and even other birds of prey. Their presence indicates a healthy, diverse ecosystem.
Similar Species
Long-eared Owl feathers are smaller and more slender. Barred Owl feathers lack the rich tawny/orange tones of the Great Horned, appearing more grey/white and brown.
Interesting Facts
Great Horned Owls can exert over 300 pounds per square inch of pressure with their talons. They are one of the few predators that regularly hunt skunks, as they have a very poor sense of smell.
Condition Notes
Good to Excellent condition. The calamus is clear, suggesting a natural molt. Slight separation of barbs (splits) is visible near the tip, likely from terminal wear before molting.
