Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Strigidae, Genus: Bubo, Species: Bubo virginianus
Family: Strigidae (Typical Owls)
- Shape
- Asymmetrical vane with a broad trailing edge and narrower leading edge; rounded tip with a slight emargination (notching) characteristic of slow, silent flight.
- Size
- Estimated 25-30 cm (10-12 inches) in length; the width is approximately 5-7 cm. This size is consistent with the large wingspan of a Great Horned Owl.

Description
This is a large, powerful feather from a Great Horned Owl. The bird itself is a massive raptor with distinctive 'ear' tufts, a white throat patch, and piercing yellow eyes. Its plumage is designed for camouflage against tree bark, featuring a complex mix of brown, grey, and black patterns.
Colour & Pattern
Mottled brown and tawny-buff base with distinct dark brown/blackish horizontal barring; 'salt and pepper' speckling (vermiculation) throughout the lighter bands; underside is paler with muted patterns.
Barb Structure
Densely pennaceous with specialized velvety 'fimbriae' (fringes) on the leading edge and a soft, pilose surface to dampen sound during flight; lower section shows plumulaceous down.
Texture & Surface
Extremely soft and velvety to the touch (matte appearance); lacks the glossy water-shedding oils of waterfowl to allow for aerodynamic silence; trailing edge is notably soft and fringed.
Key Features
Distinctive horizontal barring, velvety surface texture for silent flight, and frayed/fringed leading edges which are unique to the Strigiformes order.
Habitat
Extremely versatile; found in deciduous and evergreen forests, swamps, deserts, subarctic tundra, city parks, and agricultural areas.
Geographic Range
Resident throughout North America from the tree line to the south, and through Central and South America. Non-migratory but may wander in search of food.
Ecological Role
Apex predator; controls populations of rodents, skunks, and even other birds of prey. They are highly adaptable and occupy a vital niche in nearly every terrestrial ecosystem.
Similar Species
Long-eared Owl feathers (smaller, narrower), Red-tailed Hawk feathers (lack the velvety texture and have different banding), and Snowy Owl feathers (much whiter with different barring).
Interesting Facts
The Great Horned Owl has a gripping force of up to 500 psi in its talons, enough to break the spine of large prey. Their 'silent flight' is achieved by the specialized fringed edges of feathers like this one which break up air turbulence.
Condition Notes
Fair condition; shows some mechanical wear and fraying along the edges (vane separation), likely a molted feather found after a breeding season.
