Great Horned Owl (also known as Tiger Owl or Hoot Owl)
Primary flight feather (Remiges), likely a mid-outer primary (P6-P8) due to the strong curvature and asymmetrical vanes.

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 narrow leading edge (outer vane) and a wide trailing edge (inner vane). The tip is rounded, and the overall outline is elongated and slightly tapered towards the apex.
Size
Estimated between 10-12 inches in length. This is consistent with the primary feathers of a large Great Horned Owl, which adult birds typically have in the 25-30 cm range.
Rarity
Common. It is one of the most widespread and successful birds of prey in the Americas.

Description

This feather represents the ultimate stealth predator. The Great Horned Owl is a large, powerful bird with prominent ear tufts and striking yellow eyes. The feather's bold banding and specialized 'muffled' surface are adaptations for nocturnal hunting, allowing the bird to ambush prey silently.

Colour & Pattern

Mottled dark brown and creamy buff/white. It features broad, irregular dark brown transverse bands against a lighter buff background. The pattern is highly cryptic, mimicking tree bark (disruptive coloration). The ventral (under) side is lighter and more matte.

Barb Structure

Pennaceous structure throughout most of the vane. A key diagnostic feature is the "fimbriae" (comb-like fringes) on the leading edge and a soft, velvety pile (fine barbule extensions) on the surface, which provides silent flight.

Texture & Surface

Extremely soft and velvety to the touch. Unlike the stiff, glassy feathers of hawks, this feather has a matte, downy surface texture that dampens sound. The trailing edge is notably soft and fringed.

Key Features

Bold horizontal banding, velvety surface texture (pile), and the presence of silent-flight fringes along the leading edge.

Habitat

Extremely versatile: found in deciduous and coniferous forests, deserts, suburban parks, agricultural areas, and even rocky canyons.

Geographic Range

Resident year-round throughout North and South America, from the subarctic tree line in Alaska and Canada south to the tip of South America.

Ecological Role

Top-tier apex predator. They control populations of rodents, rabbits, and even other birds of prey. They are non-migratory and maintain territories year-round.

Similar Species

Barred Owl (Strix varia) feathers are similar but generally smaller and have more regular, cleaner-edged brown and white bars. Red-tailed Hawk feathers are much stiffer, glossy, and lack the velvety 'silent flight' coating.

Interesting Facts

Great Horned Owls have a grip strength of up to 300 psi, comparable to the bite of a large dog. They are also one of the few predators that regularly hunt skunks, as they have a very poor sense of smell.

Condition Notes

Fair to Poor. The feather shows significant 'zipper' separation (unzipped barbs) and fraying at the tip and trailing edge. This suggests it is a naturally molted feather that has been exposed to the elements or mechanical wear.
