Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Strigiformes; Family: Strigidae; Genus: Bubo; Species: virginianus
Family: Strigidae (Typical Owls)
- Shape
- Broadly spatulate with a rounded tip; relatively symmetrical vanes typical of body contour feathers rather than primary flight feathers.
- Size
- Estimated 3-4 inches (7-10 cm) in length. Broad width of approximately 1.5 inches. Consistent with large scapular or upper-back contour feathers of a Great Horned Owl.
- Rarity
- Common and widespread, though rarely seen during the day due to nocturnal habits and excellent camouflage.

Description
A large, powerful owl with prominent ear tufts and a white throat patch. The plumage is a complex mosaic of brown, gray, and white providing perfect camouflage against tree bark. They have a massive 3-5 foot wingspan and are known for their deep 'hoo-h'hoo-hoo' call.
Colour & Pattern
Alternating thick horizontal bands of dark umber/grayish-brown and creamy off-white. The dark bands are slightly mottled with finer speckles. The base is pure white and downy.
Barb Structure
The upper half is pennaceous with tightly interlocked barbs, while the base is highly plumulaceous (downy) for insulation. Features the characteristic 'fringe' or velvet-like surface that reduces noise during flight.
Texture & Surface
Velvety, soft, and slightly matte. The specialized micro-structure of the barbs creates a 'muffler' effect, though this is more pronounced in flight feathers than in these contour feathers.
Key Features
Characteristic broad brown and cream banding; velvet-like surface texture; dense white downy base; absence of the orange/buff tones seen in Long-eared Owls.
Habitat
Extremely versatile; found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and urban parks. Requires large trees for nesting/roosting.
Geographic Range
Resident throughout North and South America, from the subarctic tree line in Canada/Alaska down to the tip of South America. Non-migratory.
Ecological Role
Apex nocturnal predator; controls populations of rodents, rabbits, and other birds. Their presence indicates a healthy, diverse ecosystem with adequate prey.
Similar Species
Barred Owl (lacks the same banding density and has more 'blur' to the pattern) and Long-eared Owl (smaller, usually with more orange-buff coloration and narrower bands).
Interesting Facts
They have the most diverse diet of any North American raptor, successfully hunting prey as large as skunks, porcupines, and even other raptors like Red-tailed Hawks.
Condition Notes
Good to Fair. Some splitting/fraying along the vane edges (barb separation) suggests it was a natural molt. No obvious signs of parasite damage or sun bleaching.
