Great Horned Owl (also known as Tiger Owl or Hoot Owl)
Primary flight feather (Remex), likely from the outer wing (P6-P9 position)

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
Highly asymmetrical with a narrower leading edge and a broader trailing edge. The tip is rounded, and the leading edge shows specialized fimbriae (comblike serrations).
Size
Estimated at 10 to 12 inches (25-30 cm) in length. This is consistent with the primary feathers of a large Bubo species which typically range from 9-13 inches.
Rarity
Common. It is one of the most widespread and successful birds of prey in North America.

Description

This is a large, powerful primary feather from a Great Horned Owl. These birds are apex nocturnal predators with iconic 'ear tufts' and a wingspan of up to 5 feet. Their plumage is designed for camouflage and silent flight, allowing them to ambush prey such as rabbits, rodents, and even other raptors.

Colour & Pattern

Distinctive bold horizontal barring of dark chocolate brown or charcoal against a base of tawny-buff or ochre. The lighter bands show fine dark freckling or mottling. The underside is paler than the dorsal surface.

Barb Structure

The barbs are pennaceous and interlocked for most of the vane, but with a unique velvet-like pile (plumulaceous coating) on the surface to dampen sound. The trailing edge is soft and fringed.

Texture & Surface

Extremely soft and velvety to the touch. It has a matte appearance due to the specialized structure that eliminates wind noise. The leading edge feels slightly stiff/comb-like while the trailing edge is exceptionally flexible.

Key Features

Bold dark barring on a buffy background, velvety sound-dampening surface texture, and the presence of serrated leading-edge fimbriae characteristic of owls.

Habitat

Found in an incredibly diverse range of habitats including deciduous and evergreen forests, swamps, deserts, tundra edges, mountains, and suburban parks.

Geographic Range

Widespread throughout the Americas, from the subarctic tree line in Alaska and Canada southward through Central America and parts of South America.

Ecological Role

Apex nocturnal predator. They regulate populations of small mammals and are highly adaptable, occupying the top of the food chain in most of North America's ecosystems.

Similar Species

Short-eared Owl feathers are smaller and more yellowish; Barred Owl feathers have more regular, 'cleaner' grayish-brown bars and lack the deep tawny-orange tones seen here.

Interesting Facts

Great Horned Owls have a crushing grip of roughly 300-500 psi in their talons, which is comparable to that of a Golden Eagle. They are also known to be the primary predators of skunks, as they have a very poor sense of smell.

Condition Notes

Fair to Good. The feather shows significant wear and fraying on the trailing edge and tip (vane separation), suggesting it was either molted naturally or suffered mechanical wear from contact with vegetation.
