Great Horned Owl (Hoot Owl, Tiger Owl)
Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Strigiformes; Family: Strigidae; Genus: Bubo; Species: Bubo virginianus
Family: Strigidae (Typical Owls)
- Shape
- Broad and somewhat asymmetrical with a rounded tip. The trailing vane is wider than the leading vane, typical of flight feathers designed for silent, low-speed lift.
- Size
- Estimated at 8–10 inches (20–25 cm) in length. This is consistent with the primary feathers of a Great Horned Owl, which typically range between 7 and 11 inches.
- Rarity
- Common; they are one of the most widespread and successful owls in the Americas, though they are more often heard than seen due to their nocturnal nature.

Description
This feather belongs to the Great Horned Owl, a powerful apex predator known for its 'horns' (ear tufts) and deep hooting. The bird has a wingspan of up to 5 feet and is characterized by its bulky frame, large yellow eyes, and camouflaged brown-and-white plumage.
Colour & Pattern
Mottled brown and tawny-buff with distinct, broad dark brown transverse bands. The base color is a warm cream-beige, reflecting the 'tiger-striped' plumage of the species. The dorsal side is more intensely colored than the ventral.
Barb Structure
Pennaceous and soft with specialized plumulaceous (downy) fringes at the base. The leading edge features a diagnostic 'comb' or fimbriae that breaks up air turbulence for silent flight.
Texture & Surface
Extremely soft and velvety to the touch. It has a matte finish rather than glossy, an adaptation that prevents light reflection and dampens sound during nocturnal hunting.
Key Features
Velvety surface texture for silent flight, broad brown banding, and 'comb-like' serrations on the leading edge (fimbriae).
Habitat
Extremely adaptable; found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and urban parks with large trees.
Geographic Range
Year-round resident throughout North and South America, from the subarctic treeline in Alaska and Canada down to the southern tip of South America.
Ecological Role
Apex nocturnal predator; they control populations of rodents, rabbits, and even other birds of prey. They are considered an indicator of forest health.
Similar Species
Barred Owl (Strix varia) feathers are similar but usually show more grey-white tones and lack the warm tawny-buff base color. Red-tailed Hawk (Buteo jamaicensis) feathers are stiffer and lack the velvety 'silent flight' texture.
Interesting Facts
Great Horned Owls have a crushing grip strength of up to 500 PSI, similar to a large dog's bite. They are one of the few predators that regularly hunt skunks, as they have a very poor sense of smell.
Condition Notes
Good condition; the barbs are mostly intact though the plumulaceous base appears slightly matted, suggesting it was a molted feather found on the ground.
