Great Horned Owl (also known as 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 spatulate with a rounded tip; relatively symmetrical vane characteristic of body plumage rather than flight feathers.
- Size
- Approximately 3 to 4 inches (7.5-10 cm) in length. This is consistent with the large body contour feathers found on an adult Great Horned Owl.
- Rarity
- Common. It is the most widely distributed true owl in the Americas, though its nocturnal nature and camouflage make feathers more commonly found than the bird is seen.

Description
This feather belongs to one of the most iconic North American raptors. The Great Horned Owl is a large, thick-bodied owl with prominent ear tufts and a white throat patch. The feather reflects the bird's overall 'salt and pepper' camouflage, which allows it to blend perfectly against tree bark during the day.
Colour & Pattern
Mottled brown and grayish-white with distinct horizontal barring. The distal end shows a darker brownish tip with a clear light-colored 'window' or band, typical of the cryptic camouflage of forest owls.
Barb Structure
Plumulaceous (downy) at the base for insulation, transitioning to a soft pennaceous structure at the tip. Features the characteristic 'velvety' fringe or pilorelations to dampen sound during flight.
Texture & Surface
Extremely soft, silky, and matte. Lacks the stiff, waxy coating of waterfowl feathers, optimized instead for silent movement and thermal regulation.
Key Features
Soft, fuzzy texture; distinct horizontal brown barring on a buff/white background; rounded tip; plumulaceous base exceeding half the feather's length.
Habitat
Highly adaptable; found in deciduous and evergreen forests, swamps, deserts, subalpine fields, and urban parks/orchards.
Geographic Range
Extensive range across North and South America, from the subarctic northern tree line to the southern tip of South America. Primarily non-migratory.
Ecological Role
Apex predator. They control populations of rodents, rabbits, and even other birds of prey. They are vital indicators of forest health.
Similar Species
Long-eared Owl (smaller, more orange tones), Barred Owl (more vertical streaking on belly feathers, lacking the fine horizontal detail of the Great Horned).
Interesting Facts
Great Horned Owls have a crushing grip strength of up to 500 PSI, similar to a large German Shepherd. They are one of the few predators that regularly hunt skunks, as they have a very poor sense of smell.
Condition Notes
Fair to Good. The feather shows significant separation of the barbs (venting) and some wear at the tips, suggesting it was naturally molted or subject to environmental weathering.
