Description

This is a secondary wing feather from a Great Horned Owl, a massive apex predator characterized by its prominent ear tufts and piercing yellow eyes. The bird itself has a mottled grayish-brown plumage designed for camouflage against tree bark. It has a wingspan of up to 4.8 feet and is famous for its deep, resonant 'hoo-h'hoo-hoo-hoo' call.

Colour & Pattern

Warm ochre/tawny base color with 7-9 distinct dark brown horizontal bars; underside is lighter cream with more muted banding; rachis is cream-colored

Barb Structure

Pennaceous vane with a velvet-like 'fimbriae' pile on the surface; distal barbs form a soft fringe to dampen sound; plumulaceous at the base

Texture & Surface

Extremely soft, velvet-like surface (silent flight adaptation); matte finish with a downy, hair-like feel across the vane

Key Features

Warm tawny coloration, soft fimbriate trailing edge, and distinct broad dark barring; lack of a stiff, noisy 'snap' when flexed

Habitat

Highly adaptable; found in deciduous and evergreen forests, swamps, deserts, subalpine, and urban parks

Geographic Range

Common throughout North and South America, ranging from the Arctic treeline south to the tip of South America

Ecological Role

Apex predator; controls populations of rodents, skunks, and other small-to-medium mammals. Known as the 'tiger of the air' for its hunting prowess.

Similar Species

Long-eared Owl (smaller, thinner bars), Barred Owl (grayer tones, different barring rhythm), or Eurasian Eagle-Owl (larger, more orange tones)

Interesting Facts

The soft fringes on these feathers allow the owl to fly in near-total silence, preventing prey from hearing their approach. They have a grip strength of 300-500 psi, comparable to a Golden Eagle.

Condition Notes

Good condition; minor fraying at the base and tip suggests it is a natural molt rather than a plucked feather; no significant fault bars visible
