Family: Strigidae (Typical Owls)
- Shape
- Highly asymmetrical vane with a rounded tip; the leading edge (outer vane) is significantly narrower than the trailing edge (inner vane).
- Size
- Total length estimated at 25-30 cm (10-12 inches) when intact, consistent with the wing feathers of a large female.

Description
A large, powerful owl with prominent ear tufts and a white throat patch. This feather reflects the bird's supreme adaptation for silent, nocturnal hunting.
Colour & Pattern
Alternating broad bars of dark soot-brown to charcoal and creamy off-white to buff; the pattern is jagged or 'toothed' rather than perfectly straight.
Barb Structure
Pennaceous and tightly interlocked with a unique fimbriate (comb-like) leading edge and a soft, velvety 'velutinous' upper surface to dampen sound.
Texture & Surface
Remarkably soft and silky to the touch due to elongated barbules; the surface has a matte finish that absorbs light and sound.
Key Features
Velutinous (velvety) surface texture and the characteristic fringed leading edge designed for silent flight.
Habitat
Extremely versatile; found in deciduous and coniferous forests, deserts, suburban parks, orchards, and agricultural areas.
Geographic Range
Resident throughout North and South America, from the Arctic tree line in the north to the tip of South America in the south.
Ecological Role
Top-tier nocturnal predator; controls populations of rodents, rabbits, and even other raptors or smaller owls.
Similar Species
Barred Owl (Strix varia) feathers are smaller and have more regular, horizontal banding; Snowy Owl feathers are much whiter.
Interesting Facts
Great Horned Owls have a grip strength of over 300 pounds per square inch, comparable to the bite of a large dog.
Condition Notes
Good; minimal wear on the barbs suggests a relatively fresh molt, though some slight separation is visible at the tips.
