Great Horned Owl

Species

Bubo virginianus

Feather Type

Secondary flight feather (Remex), likely from the mid-wing (S4-S8)

Family

Strigidae (Typical Owls)

Shape

Broad and rectangular with a rounded tip; the vane is relatively symmetrical compared to outer primaries, though the trailing edge is slightly wider.

Size

Approximately 7-9 inches (18-23 cm) in length and 2.5 inches wide, which is standard for a large secondary feather from a Great Horned Owl.

Rarity

Common; however, feathers are often hidden in thick brush or under roosting trees, making them a moderately difficult find.

Color & Pattern

Mottled brown and off-white/ochre banding. The bars are thick and dark brown, alternating with lighter cream-buff spaces. There is significant grayish-brown mottling (flecking) within the lighter bands.

Barb Structure

Densely pennaceous with specialized velvety 'fringe' or 'flutings' on the leading edge and a soft, hair-like trailing edge to provide silent flight. The base contains a significant plumulaceous (downy) section.

Texture & Surface

Extremely soft, velvety, and matte. The surface lacks the glossy sheen of raptors or waterfowl, an adaptation that breaks up air turbulence to allow the owl to fly silently.

Description

This feather belongs to the 'Tiger of the Air,' a large, powerful owl with prominent ear tufts. The Great Horned Owl is a heavy-bodied raptor with a 3-5 foot wingspan, known for its deep rhythmic hooting. The feather's soft texture and 'combed' edges are high-performance tools for nocturnal hunting.

Key Features

Soft velvety texture (the 'owl silencer'), broad rounded tip, and distinct brown-and-buff horizontal banding with fine internal mottling.

Habitat

Highly adaptable; found in deciduous and evergreen forests, swamps, deserts, subalpine areas, and urban parks near Sidney, BC.

Geographic Range

Common throughout North America from the Arctic tree line south to Central and South America. Residents of Vancouver Island are generally non-migratory.

Condition Notes

Good condition; the barbs are mostly intact though the tip shows minor wear from flight or ground contact. No significant fault bars or parasitic damage visible.

Interesting Facts

Great Horned Owls can apply 300-500 pounds per square inch of pressure with their talons. They are one of the few predators that regularly hunt skunks, as they have a very poor sense of smell.

Ecological Role

Apex nocturnal predator. They control populations of rodents, rabbits, and even other birds of prey, playing a vital role in maintaining ecosystem balance.

Similar Species

Barred Owl (Strix varia) feathers have more distinct, clean horizontal bands with less internal mottling. Long-eared Owl (Asio otus) feathers are significantly smaller and narrower.
