- Shape
- Asymmetrical vane with a rounded tip; the trailing wing edge is broad and curved while the leading edge shows slight narrowing.
- Size
- Approximately 7-9 inches (18-23 cm) in length; width is roughly 1.5-2 inches (4-5 cm). This is within the standard range for a mid-wing secondary feather of this species.

Description
This is a robust flight feather from a Great Horned Owl, a powerful predator known for its 'horns' (ear tufts). The bird is a large, bulky owl with a wingspan of up to 5 feet, characterized by a white throat patch and yellow eyes. The feather's intricate mottling and specialized silent-flight edges are perfectly adapted for nocturnal hunting.
Colour & Pattern
Mottled grayish-brown base with distinct dark brown or charcoal transverse bars. The inner vane shows lighter, cream-to-white spotting and marbling, typical of owl camouflage patterns designed to mimic tree bark.
Barb Structure
Pennaceous with a specialized velvety surface (fimbriae); the distal edges feature a fine, hair-like fringe (combing) designed to suppress noise during flight.
Texture & Surface
Velvety, soft, and silent to the touch. The surface has a matte appearance with a fuzzy, hair-like pile that reduces air turbulence and sound.
Key Features
Velvet-like surface texture (fimbriae), dark horizontal banding, and fine hair-like fringes on the barbs that distinguish it from the smoother feathers of hawks or crows.
Habitat
Extremely versatile; found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and suburban parks.
Geographic Range
Resident year-round throughout North and South America, from the subarctic treeline in Alaska and Canada south to the tip of South America.
Ecological Role
Apex nocturnal predator; controls populations of rodents, rabbits, and even other birds of prey. Their presence indicates a healthy, diverse ecosystem with a robust prey base.
Similar Species
Long-eared Owl (smaller, more orange tones), Barred Owl (tighter vertical/horizontal barring, lacks 'fuzzy' texture intensity of the Bubo genus), and Great Gray Owl (larger, grayer tones).
Interesting Facts
Great Horned Owls have a crushing power in their talons of up to 500 PSI, which is enough to break the spine of large prey; they are also one of the few animals that regularly prey on skunks because they have a poor sense of smell.
Condition Notes
Good condition; slight wear at the tip and some separation of the lower barbs near the calamus (quill). No evidence of heavy parasite damage or fault bars.
