Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Strigidae, Genus: Bubo, Species: Bubo virginianus
Family: Strigidae (Typical Owls)
- Shape
- Broad and asymmetrical with a rounded tip. The leading edge (vane) is narrower than the trailing edge, typical of flight feathers designed for lift.
- Size
- Approximately 8-10 inches in length. This is consistent with the secondary feathers of a large female Great Horned Owl, which typically range from 7 to 11 inches.
- Rarity

Description
This is a large, powerful owl with prominent ear tufts and piercing yellow eyes. Its plumage provides excellent camouflage against tree bark. In flight, it has broad, rounded wings and a short tail, moving with a steady, silent beat.
Colour & Pattern
Mottled brown, tan, and cream coloration. It features distinct dark horizontal banding (bars) against a lighter, speckled background. The underside is noticeably paler than the dorsal surface.
Barb Structure
The distal edge features a specialized 'comb' or fimbriae structure for silent flight. The base is plumulaceous (downy) for insulation, while the rest is pennaceous but exceptionally soft to the touch.
Texture & Surface
Extremely soft, silky, and matte. Owl feathers lack the waxy, glossy coating of many waterbirds, which helps reduce noise but makes them less waterproof.
Key Features
Soft velvet-like texture, rounded tip, distinct dark banding, and the 'comb-like' leading edge which is a hallmark of silent-flight strigiforms.
Habitat
Highly adaptable; found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and even urban parks or suburban areas.
Geographic Range
Extensive range across the Americas, found from the treeline in the Arctic south through Central America and much of South America. Most populations are non-migratory year-round residents.
Ecological Role
Apex predator; they control populations of rodents, rabbits, and even other birds of prey. They are vital for maintaining the balance of the local small mammal population.
Similar Species
Long-eared Owl feathers are similar but much smaller and more slender. Barred Owl feathers have cleaner, more defined white-and-brown barring without as much fine mottling.
Interesting Facts
Great Horned Owls have a bite force of approximately 300 psi, comparable to a large dog. They are also known to be the primary predator of skunks, as they have a very poor sense of smell.
Condition Notes
Fair to Good. There is some separation (splitting) of the barbs along the edges, suggesting this may be a molted feather that has experienced some mechanical wear or wind damage.
