Great Horned Owl (Tiger Owl, Hoot Owl)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Strigidae, Genus: Bubo, Species: Bubo virginianus
Family: Strigidae (Typical Owls)
- Shape
- Broadly spatulate to rounded with a slightly tapered base and a soft, blunt tip. The vanes are relatively symmetrical for a body feather.
- Size
- Approximately 3.5 to 4.5 inches (9-11 cm) in length. This is consistent with larger contour feathers found on the upper breast or flank of an adult Great Horned Owl.
- Rarity
- Common. It is one of the most widespread and successful owl species in the Americas.

Description
This feather belongs to the Great Horned Owl, a powerful apex predator known for its iconic 'ear' tufts and yellow eyes. The bird is mottled grey-brown above with heavy barring below and a white throat patch. Their soft feathers allow them to fly almost silently to ambush prey.
Colour & Pattern
Complex patterning featuring a warm tawny or cinnamon-buff ground color at the tip, transitioning into bold, dark brown to charcoal horizontal bars. The distal end shows fine 'salt and pepper' speckling (vermiculation).
Barb Structure
The feather shows a classic owl structure with a dense, velvet-like 'frazil' on the surface and plumulaceous (fluffy) barbs at the base for insulation. The pennaceous section is soft and flexible.
Texture & Surface
Extremely soft, silky, and velvet-like. It lacks the stiff, glossy finish of diurnal raptors, instead appearing matte to absorb sound and provide maximum insulation.
Key Features
Characteristic horizontal 'owl barring', soft velvety texture, vermiculated tip, and a rich cinnamon-buff wash that distinguishes it from the grey-toned Barred Owl.
Habitat
Highly adaptable: found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and even urban parks or suburban woodlots.
Geographic Range
Resident throughout North and South America, from the subarctic tree line in Canada/Alaska down to the southern tip of South America. They are non-migratory.
Ecological Role
Apex nocturnal predator. They control populations of rodents, skunks, and even other raptors, serving as a critical indicator of ecosystem health.
Similar Species
Barred Owl (Strix varia) feathers are similar but typically lack the rich cinnamon/orange tones and have more defined, cleaner grey-brown barring. Long-eared Owl feathers are smaller and narrower.
Interesting Facts
Great Horned Owls have a clenching force of up to 500 psi in their talons and are one of the few consistent predators of skunks, as they have a very poor sense of smell.
Condition Notes
Fair to Good. There is significant 'zipper' separation of the barbs (mechanical damage) and some fraying at the tip, likely from preening or environmental wear.
