Great Horned Owl (Tiger Owl, Hoot Owl)

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

Family: Strigidae (Typical Owls)

Shape
Broadly rounded at the tip with a slightly asymmetrical vane, typical of the inner wing feathers. The profile is relatively wide and rectangular compared to primary feathers.
Size
Approximately 8 to 10 inches in length. This size is consistent with the secondary feathers of a large female or male Great Horned Owl, which average 20-25 cm.
Rarity
Common and widespread, though rarely seen during the day due to their nocturnal nature and effective camouflage.

Description

This feather belongs to one of the most powerful apex predators of the night. Adult Great Horned Owls are large, thick-bodied birds with prominent ear tufts and striking yellow eyes. Their plumage is a complex mosaic of browns, grays, and whites designed to mimic tree bark. In flight, they are nearly silent, moving through the woods like a ghost to surprise prey as large as skunks and other raptors.

Colour & Pattern

Mottled grayish-brown base with 4-5 distinct dark chocolate brown horizontal bands (bars). The dorsal surface shows a fine 'salt and pepper' speckling between the bands, providing excellent camouflage.

Barb Structure

Pennaceous with a specialized velutinous (velvety) surface. The leading edge shows characteristic fimbriae (fine serrations) which reduce noise during flight. The base transition is plumulaceous (downy).

Texture & Surface

Extremely soft, silky, and matte. The dorsal surface has a fine pile or 'muff' that dampens sound. It lacks the glossy, stiff texture found in day-hunting raptors.

Key Features

Broad dark bands, velvety 'hush' texture on the surface, soft fimbriae on the edges, and a sturdy white rachis.

Habitat

Highly adaptable; found in deciduous and evergreen forests, swamps, desert canyons, subalpine meadows, and even urban parks or agricultural areas.

Geographic Range

Resident throughout North and South America, from the northern tree line in Alaska and Canada down through Central America to parts of South America. They do not migrate.

Ecological Role

Apex nocturnal predator. They control populations of rodents, rabbits, and even other medium-sized birds. They are vital indicators of forest health.

Similar Species

Red-tailed Hawk feathers (lack the velvety texture and have different banding), Barred Owl feathers (usually have paler, more uniform gray-white bands and are slightly smaller).

Interesting Facts

Great Horned Owls have a bite pressure of up to 500 psi. They are one of the few animals that regularly prey on skunks because they have a very poor sense of smell.

Condition Notes

The feather is in good condition, likely a naturally molted specimen. There is some minor separation of the barbs near the base (plumulaceous area), and the tip shows very slight wear.
