Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Strigidae, Genus: Bubo, Species: Bubo virginianus · Strigidae (Typical Owls) · Primary flight feather (likely P8 or P9)
Species
Bubo virginianus
Feather Type
Primary flight feather (likely P8 or P9)
Family
Strigidae (Typical Owls)
Shape
Asymmetrical with a distinctively tapered tip; features a prominent leading-edge serration (fimbriae).
Size
Approximately 10-12 inches (25-30 cm) in length; broad vane consistent with a large raptor of this wingspan.
Rarity
Common and widespread throughout its range, though feathers are often hidden in dense roosts.
Color & Pattern
Mottled ochre and tawny-buff base with bold, dark brown horizontal bands (bars); ventral side is paler and more matte.
Barb Structure
Pennaceous with specialized velvety 'flutings' on the surface and a comb-like fringe (fimbriae) on the leading edge for silent flight.
Texture & Surface
Velvety, soft, and extremely quiet to the touch; matte finish designed to absorb sound rather than reflect light.
Description
A magnificent, powerful owl with iconic 'horns' (ear tufts) and yellow eyes. This feather reflects its apex-predator status, featuring the specialized morphology required for silent nocturnal hunting.
Key Features
Leading-edge serrations (comb), velvety surface texture, and the specific tawny-and-brown banding characteristic of Bubo virginianus.
Habitat
Highly adaptable: found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and urban parks.
Geographic Range
Extensive range across North and South America, from the subarctic tree line to the southern tip of Argentina; largely resident.
Condition Notes
Good; shows some minor ruffling (unzipped barbs) at the tip and trailing edge, likely from natural wear or contact with brush.
Interesting Facts
The 'comb' on the leading edge of this feather breaks up air turbulence, allowing the owl to fly silently and ambush prey that relies on hearing.
Ecological Role
Apex nocturnal predator, controlling populations of rodents, rabbits, and even other birds of prey.
