Great Horned Owl (also nicknamed the Tiger Owl or Hoot Owl)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Strigidae, Genus: Bubo, Species: Bubo virginianus
Family: Strigidae (Typical Owls)
- Shape
- Broadly rounded tip with a moderately asymmetrical vane, characteristic of a secondary wing feather. It lacks the sharp taper of a primary flight feather.
- Size
- Approximately 7 to 9 inches (18-23 cm) in length and 2 inches wide, consistent with the inner secondary feathers of a large female or male Great Horned Owl.
- Rarity
- Common; it is the most widely distributed and successful owl species in the Americas, though its nocturnal nature makes visual sightings less frequent than audio encounters.

Description
This feather belongs to one of the most powerful predators of the night. The Great Horned Owl is a large bird with prominent ear tufts, a white throat patch, and piercing yellow eyes. Their plumage is a complex tapestry of grays, browns, and buffs designed to mimic tree bark. This specific secondary feather shows the characteristic soft-edged fringe that allows the owl to fly silently over prey.
Colour & Pattern
Mottled and barred with dark umber brown, buffy tan, and creamy white. The darker bars are somewhat irregular, a classic 'camouflage' pattern for woodland concealment. The underside is generally paler with less distinct mottling.
Barb Structure
Pennaceous throughout most of the vane but with specialized velvet-like pile (fimbriae) on the dorsal surface and a soft, fringed trailing edge. These features facilitate silent flight by breaking up air turbulence.
Texture & Surface
Extremely soft, silky, and 'fuzzy' to the touch. It has a matte finish without the gloss found in waterfowl or raptor feathers, designed to absorb sound rather than repel water.
Key Features
Velvety dorsal surface texture, trailing edge fringe (comb-like), and the specific mottled-brown and buff-barring pattern unique to Bubo virginianus.
Habitat
Highly adaptable; found in deciduous and evergreen forests, swamps, desert scrub, agricultural areas, and even urban parks or suburban woodlots.
Geographic Range
Extends throughout North America from the Arctic tree line south through Central America and much of South America. They are permanent residents (non-migratory).
Ecological Role
Apex nocturnal predator. They control populations of rodents, rabbits, and even other birds of prey. Their presence indicates a healthy, diverse ecosystem with sufficient prey biomass.
Similar Species
Long-eared Owl feathers (smaller, more orange-buff), Barred Owl feathers (more distinct, clean brown-and-white horizontal bars), and Great Gray Owl feathers (much larger and more grey-toned).
Interesting Facts
Great Horned Owls have a crushing power in their talons of up to 500 psi—enough to break the spine of a large rabbit or even a small hawk. They are also one of the few predators that regularly eat skunks because they have a very poor sense of smell.
Condition Notes
The feather appears weathered with some separation and fraying in the upper vane (splitting). There is visible wear on the trailing edge, suggesting it was likely a molted feather found after a full season of use. Grade: Fair.
