Great Horned Owl (also known as Tiger Owl or Hoot Owl)
Primary flight feather (remex), likely from the outer wing (P7-P9 range).

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
Distinctly asymmetrical vane with a broad trailing edge and a narrow leading edge; the tip is rounded but shows a slight taper characteristic of outer primaries.
Size
Estimated at 10 to 12 inches (25-30 cm) in length. This is consistent with the primary feathers of a large female Great Horned Owl, which tip the scales of sizing for this species.
Rarity
Common. It is one of the most widespread and successful birds of prey in the Americas.

Description

This is a large, powerful owl with prominent ear tufts (plumicorns) that give it a cat-like silhouette. They possess a 3-5 foot wingspan and are mottled gray-brown above with heavy barring on the belly. As apex nocturnal predators, their feathers are specialized for total silence during flight.

Colour & Pattern

Base color is a creamy buff to off-white, marked with 6-8 bold, dark brown horizontal bars. The bars are slightly jagged and mottled. The ventral (underside) is paler and more matte than the dorsal side.

Barb Structure

Pennaceous throughout most of the vane with a plumulaceous (downy) base. A key diagnostic feature is the fine, velvet-like pilosity (fuzz) on the dorsal surface and a slight fimbriate (comb-like) edge on the leading vane to muffle sound.

Texture & Surface

Velvety and exceptionally soft to the touch. Unlike the stiff, glassy texture of a hawk feather, this has a matte finish and a 'hairy' surface texture designed to break up air turbulence.

Key Features

Bold dark brown banding on a buff background, velvety surface texture for silent flight, and a distinct white/creamy base with plumulaceous down.

Habitat

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

Geographic Range

Year-round resident across most of North and South America, ranging from the subarctic tree line in Alaska and Canada down to the southern tip of South America.

Ecological Role

Apex predator. They control populations of rodents, skunks, and even other birds of prey. Their presence indicates a healthy, diverse local food web.

Similar Species

Long-eared Owl feathers are similar but much smaller and narrower. Barred Owl feathers have more regular, even chocolate-brown banding and lack the warm buff/orange tones often seen in Great Horned Owls.

Interesting Facts

Great Horned Owls have a grip strength of over 300 psi, comparable to a large German Shepherd dog. They are also one of the few predators that regularly hunt and eat skunks due to their poor sense of smell.

Condition Notes

Good to Fair. There is a visible split (vane separation) in the lower third of the trailing vane. The downy base is intact, and the colors are vibrant, suggesting a relatively recent molt.
