Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Strigiformes; Family: Strigidae; Genus: Bubo; Species: Bubo virginianus
Family: Strigidae (Typical Owls)
- Shape
- Broad, rounded, and slightly spatulate with a highly asymmetrical plume distribution near the base.
- Size
- Approximately 2.5 to 3.5 inches in length. This is consistent with a medium-sized body contour feather from the flank or lower breast of a Great Horned Owl.

Description
This feather represents the iconic Great Horned Owl, a massive avian predator with a wingspan of up to 5 feet. The owl is characterized by its prominent 'horns' (ear tufts), a white throat bib, and yellow eyes. This specific feather shows the intricate banding that helps the bird blend into the shadows of the forest canopy during the day.
Colour & Pattern
Mottled grayish-brown base with distinct dark brown horizontal barring. The ventral side is paler, almost white. The pattern is typical of the camouflage 'cryptic' coloration used to mimic tree bark.
Barb Structure
Mixed pennaceous and plumulaceous structure. The proximal (bottom) half is highly plumulaceous (downy) for insulation, while the distal (top) half is pennaceous with velvet-like pile for silent flight and camouflage.
Texture & Surface
Extremely soft, silky, and velvet-like. It lacks the stiff, glossy 'scritch' of a hawk feather, as owl feathers are evolutionarily designed to absorb sound for silent movement.
Key Features
Distinguished by the soft, 'velvety' texture unique to Strigiformes and the specific horizontal dark-on-tan barring pattern that is thicker than that of a Long-eared Owl.
Habitat
Found in a vast variety of habitats including deciduous and evergreen forests, swamps, deserts, tundra edges, and even urban parks or suburban areas.
Geographic Range
Year-round resident across most of North America (from the tree line in the Arctic south to Mexico) and throughout much of South America.
Ecological Role
Apex predator. They control populations of rodents, skunks, and even other birds of prey. Their presence is a sign of a healthy, productive ecosystem with ample prey.
Similar Species
Long-eared Owl (Asio otus) feathers have thinner, more frequent bars. Barred Owl (Strix varia) feathers tend to be more brown/white without the same tawny-orange highlights.
Interesting Facts
The 'horns' are essentially tufts of feathers and have nothing to do with hearing. Great Horned Owls have a crushing grip strength of up to 200-500 pounds per square inch, making them the tigers of the sky.
Condition Notes
Fair to Good. The distal tip shows significant wear and fraying (vane separation), likely due to contact with vegetation or grooming. The downy base remains largely intact and fluffy.
