Great Horned Owl
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Strigidae, Genus: Bubo, Species: Bubo virginianus · Strigidae (Typical Owls) · Contour feather (Body/Mantle); possibly from the upper wing coverts or dorsal region.
Species
Bubo virginianus
Feather Type
Contour feather (Body/Mantle); possibly from the upper wing coverts or dorsal region.
Family
Strigidae (Typical Owls)
Shape
Broadly rounded tip with a slightly asymmetrical vane; the feather is ovate in overall outline with a wide, soft base.
Size
Estimated 4-5 inches in length. This is consistent with a large body contour or secondary covert feather from an adult Great Horned Owl.
Rarity
Common. It is one of the most widespread and adaptable owls in the Americas, though its nocturnal nature makes direct sightings less frequent than its vocalizations.
Color & Pattern
A complex 'salt and pepper' motif featuring dark brown to near-black transverse bars over a background of tawny-buff and grayish-white. This is highly cryptic, mimicking tree bark.
Barb Structure
Highly specialized structure with a velvety, plumulaceous base for insulation and a pennaceous upper portion. The upper edge features a soft, fringed surface (fiery cilia) characteristically designed for silent flight.
Texture & Surface
Extremely soft and silky to the touch. The surface has a matte appearance with a specialized downy coating that reduces air turbulence and friction, allowing for silent movement.
Description
The Great Horned Owl is a massive, powerful raptor with prominent ear tufts and striking yellow eyes. This feather exemplifies its 'tiger of the air' persona, featuring the dense, mottled camouflage necessary for blending into woodland high-canopy roosts during the day.
Key Features
Rounded tip, velvety 'owl-down' texture for noise suppression, and distinctive erratic dark brown horizontal barring against a buff background.
Habitat
Extremely distal habitats ranging from deciduous and coniferous forests to deserts, suburban parks, and rocky canyons.
Geographic Range
Year-round resident throughout North and South America, ranging from the subarctic tundra of Canada and Alaska down to the southern tip of South America.
Condition Notes
Good condition. There is some minor separation of the barbs near the mid-section, likely from natural wear or the molting process, but the characteristic patterning remains vibrant.
Interesting Facts
The Great Horned Owl has no sense of smell and is one of the only consistent predators of skunks. Their grip can exert over 300 pounds per square inch of pressure, enough to sever the spine of large prey.
Ecological Role
Apex predator. They control populations of rodents, rabbits, and even other birds of prey. They are vital indicators of ecosystem health due to their position at the top of the food chain.
Similar Species
Long-eared Owl feathers are similar but smaller and more slender. Barred Owl feathers have wider, more regular brown and white bars and lack the tawny-orange wash often found in Great Horned specimens.
