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 rounded and fan-like; notably symmetrical with a high proportion of plumulaceous (downy) structure at the base.
- Size
- Approximately 2.5 to 3.5 inches (6.5-9 cm) in length. This is consistent with medium-sized contour feathers found on the underparts of large owls.
- Rarity
- Common; one of the most widespread and successful owls in the Western Hemisphere.

Description
This feather is a soft body contour feather from a Great Horned Owl. These birds are large, powerful predators with distinctive ear tufts (plumicorns) and yellow eyes. They have a wingspan of up to 5 feet and are known for their deep 'hoo-h'hoo-hoo' vocalizations. Their plumage is designed for camouflage against tree bark.
Colour & Pattern
Transverse barring pattern consisting of distinct, dark brownish-gray/charcoal bands against a cream or off-white base. The bands are slightly irregular and characteristic of the 'mottled' look of Bubo virginianus.
Barb Structure
Exhibits a large plumulaceous (downy) base for insulation. The distal pennaceous barbs are loose and soft, featuring 'frings' or velvet-like barbules typical of owls to reduce noise during flight.
Texture & Surface
Velvety, soft, and matte. It lacks the waxy or stiff texture of diurnal raptor feathers. The surface is designed to absorb sound rather than repel water.
Key Features
Dark transverse horizontal barring; downy base constituting nearly half the feather length; extremely soft 'velvet' texture typical of Strigiformes.
Habitat
Extremely versatile; found in deciduous and coniferous forests, swamps, deserts, agricultural areas, and even urban parks. Requires semi-open landscapes for hunting.
Geographic Range
Resident throughout North and South America, from the subarctic tree line in Canada/Alaska down to the southern tip of South America.
Ecological Role
Apex nocturnal predator; controls populations of rodents, rabbits, and even other birds of prey. They are highly adaptable and serve as an indicator of ecosystem health.
Similar Species
Long-eared Owl (smaller, more orange tones), Barred Owl (more vertical streaking on bellies, though breast is barred), and Snowy Owl (whiter, thicker down).
Interesting Facts
Great Horned Owls can apply up to 300 pounds per square inch of pressure with their talons. They are one of the few predators that regularly hunt and eat striped skunks because they have a poor sense of smell.
Condition Notes
Fair to Poor. The feather shows significant structural damage (splitting of the vanes) and many barbs have become unzipped or lost their adhesion, likely due to physical wear or being molted/dropped.
