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
- Slightly asymmetrical towards the base but generally rounded and broad. The tip is blunt and rounded, typical of a slow-flying, silent predator.
- Size
- Estimated at 3.5 to 4.5 inches (9-11 cm) in length. This is consistent with the medium-sized decorative body and covert feathers of a large owl species.
- Rarity
- Common; it is one of the most widespread and successful raptors in the Western Hemisphere.

Description
This feather belongs to a large, powerful owl with prominent ear tufts and piercing yellow eyes. The bird has a 3-5 foot wingspan and a deep, rhythmic hooting call. Its plumage is designed for total stealth and cryptic camouflage against tree bark.
Colour & Pattern
Mottled grayish-brown and buff with distinct transverse dark brown bars or bands. The 'tiger-striped' look is highly characteristic, with a creamy-white base and intermittent tawny highlights.
Barb Structure
The upper portion is pennaceous and tightly interlocked, while the bottom third is heavily plumulaceous (downy). A diagnostic feature is the fine, velvet-like fringe (fimbriae) on the barbs that muffles sound during flight.
Texture & Surface
Extremely soft and velvety to the touch. It has a matte finish rather than a glossy one, which helps in camouflage and noise reduction by absorbing light and sound.
Key Features
Transverse 'tiger-stripe' banding, velvety/fuzzy surface texture for silent flight, and a large plumulaceous base for insulation.
Habitat
Incredibly diverse; found in deciduous and evergreen forests, swamps, deserts, tundra edges, and even suburban parks or urban areas.
Geographic Range
Resident year-round throughout North and South America, ranging from the Arctic tree line in the north to the tip of South America.
Ecological Role
Apex nocturnal predator. They control populations of rodents, rabbits, and other birds. As an adaptable species, they are vital indicators of local ecosystem health.
Similar Species
Barred Owl feathers (more regular, cleaner white/brown banding) and Long-eared Owl feathers (shorter, more narrow, different banding frequency).
Interesting Facts
Great Horned Owls have a crushing grip strength of up to 500 PSI, similar to a large dog, and are one of the few animals that regularly hunt skunks since they have a poor sense of smell.
Condition Notes
The feather appears to be in excellent condition, likely a naturally molted specimen. The barbs are mostly intact with no visible fault bars or parasite damage.
