Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Strigiformes; Family: Strigidae; Genus: Bubo; Species: Bubo virginianus
Family: Strigidae (Typical Owls)
- Shape
- Broad and slightly asymmetrical; the tip is rounded and blunt, which is characteristic of owls to facilitate slow, silent flight.
- Size
- Estimated 8-11 inches in length (20-28 cm). This matches the typical flight feather dimensions for an adult Great Horned Owl.
- Rarity
- Common and widespread throughout its range, though they are nocturnal and more often heard than seen.

Description
This feather belongs to the Great Horned Owl, a powerful apex predator with a wingspan of up to 5 feet. The bird is known for its large size, prominent ear tufts, and deep 'hoo-h'hoo-hoo' call. Its plumage is a mosaic of browns, greys, and blacks designed for perfect forest concealment.
Colour & Pattern
Base color is a creamy white to buff-tan, marked with distinctive, broad dark brown transverse bands (barring). The bands are slightly irregular, typical of owl camouflage.
Barb Structure
The distal edge features a fimbriate (comb-like) fringe for noise reduction. The proximal structure is plumulaceous (downy) at the base and pennaceous toward the tip.
Texture & Surface
Extremely soft and velvety to the touch. It has a matte finish rather than a glossy one, which helps break up light and sound.
Key Features
Soft fimbriate edges (fringed), broad dark brown barring on a buff background, and a dense downy base that lacks the stiffness of diurnal raptor feathers.
Habitat
Highly adaptable; found in deciduous and evergreen forests, swamps, deserts, tundra edges, and even urban parks or suburban areas.
Geographic Range
Year-round resident across most of North America, from the subarctic to Central and South America. They do not typically migrate.
Ecological Role
Apex predator; controls populations of rodents, rabbits, and other birds. They are an essential indicator of ecosystem health.
Similar Species
Long-eared Owl feathers are smaller with narrower barring; Red-tailed Hawk feathers are much stiffer, glossier, and lack the soft, silent-flight fringe.
Interesting Facts
Great Horned Owls have no sense of smell, allowing them to frequently prey on skunks. Their serrated wing feathers disrupt airflow so effectively they are virtually silent in flight.
Condition Notes
Good condition; the barbs show some minor separation (fraying) near the tip, likely due to natural wear or the molting process.
