Family: Strigidae (Typical Owls)
- Shape
- Broad, slightly asymmetrical vane with a rounded tip; characteristic of secondary wing feathers providing lift.
- Size
- Estimated 7-9 inches (18-23 cm) in length and 2-2.5 inches in width, consistent with the mid-wing secondaries of a large owl.
- Rarity
- Common (though feathers are less frequently found due to the bird's nocturnal habits and secretive roosting).

Description
A large, powerful owl with prominent ear tufts and a white throat patch. This feather reflects the species' apex predator status, designed for stealthy, nocturnal hunting.
Colour & Pattern
Rich ochre/tawny base color with 6-8 distinct dark brown or charcoal transverse bars. The tip shows fine vermiculation (mottling) typical of owl camouflage.
Barb Structure
Upper surface is soft and velvety with a dense 'fimbria' or muff-like pile; trailing edge shows fine fringing; plumulaceous (downy) base for insulation.
Texture & Surface
Incredibly soft, quiet, and matte. The surface lacks the glassy/reflective quality of hawks to ensure 'silent flight' by breaking up air shear.
Key Features
Velvety surface texture, distinct dark banding on a tawny background, and a fringed trailing edge that muffles sound during flight.
Habitat
Highly adaptable: found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and even suburban parks.
Geographic Range
Extensive range across North and South America, from the subarctic tree line to the southern tip of South America; largely non-migratory.
Ecological Role
Apex predator; regulates populations of rodents, rabbits, and other birds. Highly sensitive to secondary poisoning from rodenticides.
Similar Species
Long-eared Owl feathers are smaller and narrower; Barn Owl feathers lack the bold dark banding and are more orange/white; Red-tailed Hawk feathers are stiff and glossy.
Interesting Facts
Great Horned Owls have a crushing grip of 300-500 psi, comparable to a large dog, and they are one of the few predators that regularly hunt skunks.
Condition Notes
Good; showing some wear and separation at the distal barbs (likely a molted feather), but the pigmentation and rachis remain strong.
