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 and rectangular with a rounded tip; the vane is slightly asymmetrical, which is characteristic of secondary feathers located closer to the body rather than the wingtip.
Size
Estimated at 8.5 to 10 inches (21-25 cm) in length. This is consistent with the secondary feathers of an adult Great Horned Owl, which typically range from 20-28 cm.
Rarity
Common. They are the most widely distributed owl in the Americas, though feathers are often hidden in dense roosting vegetation.

Description

This feather belongs to the 'Tiger of the Woods,' a large, powerful owl with prominent ear tufts and piercing yellow eyes. The bird stands up to 25 inches tall with a 5-foot wingspan. Its plumage is a complex camouflage of mottling and barring.

Colour & Pattern

Base color is a warm buffy-tan to creamy white. It features 6-7 broad, dark chocolate-brown transverse bars. The ventral side is lighter and more matte. The rachis is pale cream, almost white.

Barb Structure

Pennaceous structure with a specialized velvety (fimbriate) dorsal surface; the barbs are soft and lack the stiff interlocking of most raptors. A fine, comb-like fringe (serrae) is present on the leading edge (though subtle in photos) to dampen sound.

Texture & Surface

Incredibly soft, velvety, and matte. Unlike hawk feathers which are glossy and stiff, this is designed for 'silent flight'. It feels silky and has a pillowy loftiness due to long barbules.

Key Features

Broad, dark transverse bands on a buff base; rounded tip; velvety 'silent flight' texture; and a robust, pale-colored rachis.

Habitat

Highly adaptable: found in deciduous and evergreen forests, swamps, deserts, agricultural areas, and even suburban parks or urban woodlots.

Geographic Range

Extremely widespread across North and South America, ranging from the subarctic tree line in Alaska and Canada down through Central America to the tip of South America. Non-migratory resident.

Ecological Role

Apex predator. They control populations of rodents, skunks, and even other birds of prey. They are vital indicators of ecosystem health due to their position at the top of the food chain.

Similar Species

Long-eared Owl feathers are similar but much smaller and narrower. Red-tailed Hawk feathers are stiff, glossy, and have sharper, more defined banding without the velvety texture.

Interesting Facts

The Great Horned Owl has a grip strength of 300-500 psi, comparable to a Golden Eagle, allowing them to hunt prey as large as skunks and small deer. Their velvet-covered feathers break up air turbulence, making their flight completely silent to their prey.

Condition Notes

Fair to Good. There is significant 'zipper' separation (parting of the barbs) in the mid-vane, likely due to mechanical stress or handling after it was molted. No obvious parasite damage.
