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
- Highly asymmetrical vane typical of flight feathers; the inner vane is much broader than the outer vane. The tip is rounded and shows a slight emarginated shape on the leading edge to reduce turbulence.
- Size
- Approximately 10 to 12 inches (25-30 cm) in length. This is consistent with the primary feathers of a large female Great Horned Owl, which are among the largest owl species in North America.
- Rarity
- Common; they are the most widely distributed owl in the Americas, though their nocturnal nature makes them more often heard than seen.

Description
This feather belongs to the Great Horned Owl, a powerful apex predator known for its large size, prominent ear tufts, and piercing yellow eyes. Its plumage is a complex mosaic of brown, gray, and buff, designed to mimic bark and shadows. In flight, they are silent ghosts, capable of taking prey larger than themselves.
Colour & Pattern
Mottled brown and cream/buff banding. The dorsal side shows dark chocolate-brown bars alternating with lighter tawny-beige sections. The underside is paler with muted versions of the same pattern. The mottling provides excellent camouflage against tree bark.
Barb Structure
Features a specialized velvet-like pile (fimbriae) on the dorsal surface and a comb-like fringe (serrations) on the leading edge (outer vane). These structures effectively dampen sound by breaking up air turbulence.
Texture & Surface
Incredibly soft and silky to the touch due to the 'fluff' on the surface. Unlike the stiff, noisy feathers of a hawk, this feather feels velvet-like, designed for near-silent flight.
Key Features
Bold dark brown transverse banding, velvety 'hush' texture on the vane, and the presence of fine serrations on the leading edge which are unique to owls.
Habitat
Highly adaptable, found in deciduous and coniferous forests, deserts, subarctic tundra, urban parks, and agricultural areas. Requires nesting sites like old raptor nests or cliff ledges.
Geographic Range
Extensive range across North and South America, from the tree line in Alaska and Canada south to the tip of South America. They are mostly non-migratory year-round residents.
Ecological Role
Apex predator that controls populations of rodents, rabbits, and even other birds of prey. They are vital for maintaining ecological balance in their various habitats.
Similar Species
Long-eared Owl feathers are similar but much smaller and narrower. Barred Owl feathers have cleaner, more defined horizontal bars without the heavy mottling seen here.
Interesting Facts
The Great Horned Owl has a grip strength of up to 500 PSI, comparable to the bite of a large dog. They are one of the few animals that regularly prey upon skunks because they have a very poor sense of smell.
Condition Notes
Good to Excellent. The feather appears mostly intact with minimal vane separation (unziping). Some slight wear at the tip suggests it may have been a molted feather from a mature bird.
