Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Strigidae, Genus: Bubo, Species: Bubo virginianus
Family: Strigidae (Typical Owls)
- Shape
- Asymmetrical vane typical of flight feathers, with a broad, rounded tip and a slightly curved outline.
- Size
- Estimated 8-10 inches (20-25 cm) in length; the width is approximately 2.5 inches. This is consistent with a secondary wing feather of a large adult owl.

Description
This is a robust wing feather from the Great Horned Owl, a powerful nocturnal predator known for its 'horns' (ear tufts) and yellow eyes. The bird has a wingspan of up to 5 feet and a mottled camouflage plumage designed for concealment in trees.
Colour & Pattern
Bold alternating horizontal bands of dark chocolate brown/black and creamy off-white. The dark bands are thick and well-defined, while the base transitions into a stark white downy section.
Barb Structure
Pennaceous throughout the majority of the vane with a distinct soft, plumulaceous base; features a specialized 'velvet' or fringed leading edge to dampen sound during flight.
Texture & Surface
Extremely soft and silky to the touch (velvety) due to specialized barbules that minimize air turbulence; matte finish with no iridescence.
Key Features
Distinctive broad dark banding, velvety sound-dampening surface, and a stark white plumulaceous base near the calamus.
Habitat
Highly adaptable; found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and suburban parks.
Geographic Range
Resident throughout North and South America, from the subarctic tundra of Canada to the southern tip of South America.
Ecological Role
Apex predator; controls populations of rodents, rabbits, and even other birds of prey. They are vital indicators of forest health.
Similar Species
Barred Owl (Strix varia) feathers are similar but generally smaller with less distinct, more 'blurry' brown banding. Red-tailed Hawk feathers have similar banding but lack the velvety, silent-flight texture.
Interesting Facts
Great Horned Owls have specialized feathers that allow for 'silent flight,' enabling them to ambush prey without being heard. They have the most diverse diet of any North American raptor.
Condition Notes
Good condition; slight fraying at the very tip and along the trailing edge suggests it was molted naturally rather than lost to trauma.
