Barn Owl
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Tytonidae, Genus: Tyto, Species: Tyto alba · Tytonidae (Barn Owls) · Secondary Flight Feather (Remiges)
Species
Tyto alba
Feather Type
Secondary Flight Feather (Remiges)
Family
Tytonidae (Barn Owls)
Shape
Asymmetrical with a broad vane; slightly rounded tip, with characteristic softness at the edges
Size
Approximately 15-18 cm (6-7 inches) in length; consistent with a mid-secondary flight feather of a medium-sized owl.
Rarity
Common, though their nocturnal nature and silent flight make them difficult to spot without effort.
Color & Pattern
Pale ochre to golden-buff dorsal surface with subtle, fine greyish-brown vermiculation (mottling) near the tip. The ventral surface is much paler, nearly white. The color is derived from pheomelanin.
Barb Structure
Pennaceous vane throughout most of the length; however, the leading edge features a specialized fringe (fimbriae) and the surface is covered in a soft, plumulaceous velvet (velutinum) to dampen sound.
Texture & Surface
Extremely soft, silky, and velvet-like to the touch. It has a matte appearance with no gloss or iridescence, designed to absorb sound rather than reflect light.
Description
The Barn Owl is a medium-sized, ghostly white-to-buff raptor with a distinctive heart-shaped facial disk. They lack ear tufts and possess long legs. This feather exhibits the warm, toasted-honey tones typical of the bird's upperparts, which contrast sharply with their snow-white underparts.
Key Features
Heart-shaped facial disk (bird), velvet-like surface texture (feather), and the absence of dark heavy barring found in other large owls.
Habitat
Open country, grasslands, agricultural fields, and marshes; nests in hollow trees, cliff cavities, and human structures like barns and silos.
Geographic Range
One of the most widespread birds in the world; found on every continent except Antarctica. Resident across much of North America, Europe, Africa, and Australia.
Condition Notes
Good condition; minor separation of barbs in the mid-vane (preening could fix). Calamus is clear, suggesting a natural molt.
Interesting Facts
Barn Owls have asymmetrical ear openings, allowing them to triangulate the exact position of a mouse under snow or vegetation in total darkness.
Ecological Role
Apex nocturnal predator of small mammals; acts as a critical biological control for rodent populations.
Similar Species
