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
- Distinctly asymmetrical vane with a rounded tip; the outer (leading) edge is much narrower than the inner (trailing) edge, providing aerodynamic stability for silent flight.
- Size
- Approximately 25-30 cm in length. This is consistent with the large wingspan of a Great Horned Owl, where primaries typically range from 24 to 32 cm.
- Rarity
- Common; though nocturnal and difficult to see, they are one of the most widespread raptors in the Americas.

Description
A magnificent large owl with prominent ear tufts and a white throat patch. The feather reflects their 'tiger' camouflage, designed to blend into bark and shadows. They are apex nocturnal predators with a wingspan up to 4.8 feet.
Colour & Pattern
Mottled ochre-buff base with 5-7 thick, dark chocolate-brown transverse bands. The ventral surface is paler, and the rachis transitions from creamy white at the base to dark brown toward the tip.
Barb Structure
Densely packed pennaceous barbs with a velvet-like soft pile on the surface. Features a specialized fimbriate (comb-like) leading edge that breaks up air turbulence.
Texture & Surface
Extremely soft and velvety to the touch. The dorsal surface has a fine downy nap (flutings) that dampens sound, while the trailing edge has a soft fringe.
Key Features
Bold dark banding, rich buff-orange coloration, and the presence of sound-dampening velvet pile (flutings) on the vane surface.
Habitat
Highly adaptable; found in deciduous and evergreen forests, swamps, deserts, tundra edges, and suburban parks.
Geographic Range
Year-round resident across most of North America from the Arctic tree line south through Central America and parts of South America.
Ecological Role
Apex predator; controls populations of rodents, rabbits, and even other birds of prey. Currently listed as Least Concern by the IUCN.
Similar Species
Long-eared Owl feathers are smaller and narrower; Red-tailed Hawk feathers lack the velvety sound-dampening pile and have thinner, more frequent bands.
Interesting Facts
Great Horned Owls have a crushing grip strength of over 300 psi and are one of the few predators that regularly hunt skunks due to their poor sense of smell.
Condition Notes
Excellent condition; the barbs are well-aligned, indicating a relatively fresh molt with no signs of heavy wear, fault bars, or parasite damage.
