Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Strigidae, Genus: Bubo, Species: Bubo virginianus
Family: Strigidae (Typical Owls)
- Shape
- Broadly rounded tip with a slightly asymmetrical vane; the overall outline is somewhat spatulate or ovate.
- Size
- Estimated 3 to 4.5 inches in length. This is consistent with a larger body contour feather found on the back or mantle of an adult Great Horned Owl.
- Rarity
- Common and widespread, though rarely seen during the day due to their nocturnal nature and excellent camouflage.

Description
This feather exhibits the iconic 'tiger-stripe' pattern of the Great Horned Owl, a massive raptor with a wingspan up to 5 feet. The bird is known for its prominent ear tufts and piercing yellow eyes. Its plumage is a complex mosaic of brown, gray, and white designed to blend into tree bark.
Colour & Pattern
Bold horizontal banding featuring rich chocolate brown or dark umber alternating with creamy white or pale buff. The dark bands are crisp against the lighter background, a key nocturnal predator camouflage.
Barb Structure
The upper portion is pennaceous but features the characteristic velvet-like pile (fimbriae); the base is highly plumulaceous (downy) for insulation.
Texture & Surface
Extremely soft and silky to the touch. The surface has a matte appearance with a specialized soft fringe (fimbriae) that muffles sound during flight.
Key Features
Broad dark chocolate bands on a cream background, velvet-like 'muffling' texture on the vane surface, and a very fluffy, downy lower half.
Habitat
Highly adaptable; found in deciduous and evergreen forests, swamps, deserts, subalpine fields, and even urban parks or suburban areas.
Geographic Range
Extensive range across North and South America, from the subarctic tunda of Canada and Alaska to the southern tip of South America. Mostly non-migratory.
Ecological Role
Top-tier nocturnal predator. They control populations of rodents, rabbits, and even other birds of prey. They are vital indicators of ecosystem health.
Similar Species
Barred Owl feathers (Strix varia) have similar banding but are generally more grey-brown and have a more regular, 'barred' look. Long-eared Owl feathers are smaller and more intricately mottled.
Interesting Facts
Great Horned Owls are one of the few predators that regularly hunt skunks, as they have a very poor sense of smell. They are also known as 'The Great Shadow' because of their nearly silent flight.
Condition Notes
Good condition. The barbs are mostly intact, though there is some minor separation at the tip. The downy base remains lofted, suggesting a relatively recent molt.
