Great Horned Owl (also known as 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 asymmetrical with a rounded, blunt tip. The leading edge (vane) is narrower than the trailing edge, typical of secondary wing feathers.
- Size
- Estimated length 18-22 cm (7-8.5 inches) and 4-5 cm wide. This fits within the range for a mid-tier secondary feather of a large owl.
- Rarity
- Common and widespread, though feathers are often hidden in dense roosting vegetation. One of the most ubiquitous large raptors in North America.

Description
This is a classic secondary flight feather from a Great Horned Owl. These birds are bulky, barrel-shaped owls with distinctive ear tufts (plumicorns) and piercing yellow eyes. Their plumage is designed for maximal camouflage and stealth, featuring complex 'mottling' and 'barring' that mimics tree bark. Known for their deep 'hoo-h'hoo-hoo' call, they are the quintessential owl of the night.
Colour & Pattern
Alternating thick horizontal bands of dark sooty-brown and mottled buffy-white. The dark bands are crisp against the lighter, slightly translucent barring. No iridescent qualities.
Barb Structure
Pennaceous with specialized velvet-like fuzz on the surface (pii). The leading edge features a diagnostic fimbriate (comb-like) fringe to reduce turbulence for silent flight.
Texture & Surface
Soft, velvety, and matte. The surface is covered in a downy 'nap' that dampens sound, providing a muffled, non-reflective appearance compared to the glossy feathers of hawks.
Key Features
Velvety surface texture, fimbriate leading edge for silent flight, and bold, alternating dark and light horizontal barring without the fine 'vermiculation' seen in other owl species.
Habitat
Extremely adaptable; found in deciduous and coniferous forests, swamps, deserts, agricultural areas, and even suburban parks or urban cemeteries.
Geographic Range
Extensively distributed throughout North and South America, from the subarctic tree line in Alaska and Canada south to the tip of Argentina.
Ecological Role
Top-tier nocturnal predator. They control populations of rodents, skunks, and even other birds of prey. They are vital indicators of ecosystem health.
Similar Species
Barred Owl feathers are similar but generally have more even, cleaner brown-and-tan stripes with less mottling. Great Gray Owl feathers are larger and more uniformly gray/silver.
Interesting Facts
The 'silent flight' of an owl is so effective that they can fly within inches of a human ear without being heard. Their grip strength is estimated at over 300 psi, comparable to a Golden Eagle.
Condition Notes
Good to Fair. There is some noticeable fraying and separation of the barbs along the trailing edge (right side), indicating some wear from flight or exposure to the elements before molting.
