- Shape
- Symmetrical and rounded at the apex, with a broad, spatulate overall outline

Description
This is a soft body feather from the Great Horned Owl, a powerful predator with iconic 'ear tufts.' The bird is large and thick-bodied with mottled brown, grey, and white plumage and a distinct white throat patch.
Colour & Pattern
Base color is creamy-white to pure white. It features a dark brown/ochre spot at the very tip and a faint, horizontal brownish bar across the midsection of the vane.
Barb Structure
The top half is pennaceous (interlocked) while the bottom half is highly plumulaceous (downy). A soft, velvety fringe is present, which is characteristic of owls.
Texture & Surface
Extremely soft, silky, and matte. The surface lacks the glossy sheen of waterfowl feathers, instead possessing a specialized 'velvety' pile that dampens sound.
Key Features
Velvety sound-dampening texture, white base color with distinct brown tip-spotting and faint barring, and a highly fluffy lower plumulaceous section.
Habitat
Thrives in a vast array of habitats including deciduous and evergreen forests, swamps, deserts, subalpine areas, and urban parks.
Geographic Range
Resident throughout North and South America, from the subarctic tree line in the north to the southern tip of South America. Not migratory.
Ecological Role
Apex predator; they control populations of rodents, rabbits, and even other birds of prey. They are vital indicators of ecosystem health.
Similar Species
Barred Owl (Strix varia) feathers are similar but usually have heavier, more defined darker brown barring. Snowy Owl feathers are whiter with less distinct brown markings.
Interesting Facts
Owl feathers are evolved for silent flight. The soft barbs break up air turbulence, allowing the owl to approach prey without making a sound.
Condition Notes
Excellent condition; the barbs are mostly intact with no significant fault bars or signs of parasite wear, suggesting a healthy molt.
