Great Horned Owl (also known as Tiger Owl or Hoot Owl)

Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Strigidae, Genus: Bubo, Species: Bubo virginianus

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.
