Shape
Broad and slightly asymmetrical with a rounded tip; the edges show characteristic softening softening (fimbriae) for silent flight.
Size
Approximately 8 to 10 inches in length; width is about 2 inches. This fits within the standard secondary range for a large Bubo species.

Description

This is a secondary wing feather from a Great Horned Owl, a massive nocturnal predator with a wingspan up to 5 feet. The bird is characterized by its large ear tufts, intimidating yellow eyes, and deep 'hoo-h'oo-hoo' vocalization. The feather's intricate barring provides perfect camouflage against tree bark.

Colour & Pattern

Mottled brown, buff, and tan with distinct dark transverse bars (banding). The base transitions into a creamy white or pale buff downy section. The ventral side is noticeably paler than the dorsal side.

Barb Structure

Pennaceous at the tip with a prominent plumulaceous (downy) base. Features specialized velvet-like pilosity on the dorsal surface and a fimbriate (fringed) leading edge for noise reduction.

Texture & Surface

Extremely soft and velvety to the touch. It has a matte finish rather than glossy to prevent light glinting during nocturnal hunting. The surface feels almost like suede.

Key Features

Soft fimbriate edges (serrations), velvety upper surface texture, and bold dark brown transverse banding on a buff background.

Habitat

Highly adaptable: found in deciduous and evergreen forests, swamps, deserts, subarctic tundra, agricultural areas, and even urban parks.

Geographic Range

Year-round resident across most of North America from the treeline in the north down through Central America and parts of South America.

Ecological Role

Apex predator; they control populations of rodents, skunks, and hares. They are also known as 'ecological indicators' of forest health and prey availability.

Similar Species

Long-eared Owl feathers are smaller and narrower; Red-tailed Hawk feathers are stiffer, glossy, and lack the soft 'velvet' texture and fringed edges of an owl.

Interesting Facts

Great Horned Owls have a crushing grip strength of up to 500 PSI, which is enough to break the spine of large prey like skunks (their favorite meal) or even other medium-sized raptors.

Condition Notes

Fair to Good. There is significant 'zipper' separation of the barbs (venting) and some wear on the tips, suggesting it may have been molted naturally at the end of a breeding season.
