Great Horned Owl (also known as Tiger Owl or Hoot Owl)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Strigidae, Genus: Bubo, Species: Bubo virginianus
Family: Strigidae (Typical Owls)
- Shape
- Broadly rounded at the tip with a slightly asymmetrical vane, characteristic of secondary feathers or large wing coverts.
- Size
- Approximately 4 to 6 inches in length. This is consistent with inner secondary feathers or median/greater wing coverts of a large owl.
- Rarity
- Common; however, their nocturnal nature and camouflaged plumage make findable molted feathers a prize for enthusiasts.

Description
This is a classic 'barred' feather from the Great Horned Owl. The bird itself is a powerful predator with iconic 'horns' (feather tufts). It possesses a broad wingspan of 3-5 feet and a deep, rhythmic hooting call. Their plumage is designed for total camouflage against tree bark.
Colour & Pattern
Alternating thick bands of dark chocolate brown and light cream/white. The dark bands show subtle mottling, while the white bands are crisp. The dorsal surface is more vivid than the ventral.
Barb Structure
Highly specialized pennaceous structure with a 'fringed' velvety surface. The edges show fine pilular structures (fimbriae) that dampen sound.
Texture & Surface
Velvety and exceptionally soft to the touch. It has a matte finish to reduce light reflection and 'hush' barbs to eliminate the sound of air movement.
Key Features
Broad dark chocolate banding, velvety surface texture (hush), and distinctive rounded shape typical of Strigiformes.
Habitat
Extremely versatile; found in deciduous and evergreen forests, swamps, deserts, subarctic tundra, and urban parklands.
Geographic Range
Extensive range across North and South America, from the northern tree line in Alaska and Canada down to the southern tip of Argentina.
Ecological Role
Apex predator; controls populations of rodents, rabbits, and even other birds of prey. They are highly adaptable and serve as indicators of ecosystem health.
Similar Species
Barred Owl (Strix varia) feathers have similar banding but generally have more blurred, grayish-brown edges and less of a white 'pop' in the light bands.
Interesting Facts
Great Horned Owls have a crushing grip strength of up to 500 psi. They are one of the few predators that regularly hunt skunks, as they have a very poor sense of smell.
Condition Notes
Excellent condition, appearing freshly molted. Only minor separation of barbs near the base (plumulaceous region); no significant fault bars or parasitic damage visible.
