Barn Owl (also known as the Ghost Owl, Monkey-faced Owl, or Church Owl)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Strigiformes, Family: Tytonidae, Genus: Tyto, Species: Tyto alba · Tytonidae (Barn Owls) · Primary flight feather (remex), likely one of the outer primaries (P8-P10).
Species
Tyto alba
Feather Type
Primary flight feather (remex), likely one of the outer primaries (P8-P10).
Family
Tytonidae (Barn Owls)
Shape
Distinctly asymmetrical vane indicating a flight function; the outer vane is much narrower than the inner vane. The tip is slightly tapered and rounded.
Size
Estimated at 20-25 cm (8-10 inches) in length. This is consistent with the primary feathers of an adult Barn Owl, which typically range from 18 to 27 cm.
Rarity
Common but elusive due to strictly nocturnal habits. Populations may be declining locally due to habitat loss and rodendenticide use.
Color & Pattern
Predominantly white to creamy-white on the proximal two-thirds and the ventral surface. The distal third (tip) features a warm tawny-brown wash with charcoal-grey or blackish speckling and faint subterminal banding.
Barb Structure
Pennaceous and tightly interlocked throughout most of the vane, transitioning to plumulaceous (fluffy) near the base. Features a specialized velvet-like pile (frizz) on the dorsal surface and a comb-like fringe (fimbriae) on the leading edge for silent flight.
Texture & Surface
Extremely soft and silky to the touch, often described as 'velvety.' It has a matte finish rather than a glossy one, an adaptation that reduces acoustic friction.
Description
An iconic nocturnal raptor with a heart-shaped facial disc and long, feathered legs. Barn Owls lack the ear tufts seen in typical owls. Their flight is buoyant and eerily silent, allowing them to hunt small mammals by sound in complete darkness.
Key Features
Asymmetrical vane, velvety 'frizz' on the surface, white base with tawny-speckled tips, and a fine serrated edge on the leading margin.
Habitat
Open country, including grasslands, marshes, agricultural fields, and verges. They nest in cavities, including hollow trees, cliffs, and man-made structures like barns, chimneys, and steeples.
Geographic Range
One of the most widespread birds in the world, found on every continent except Antarctica. In North America, they range from the northern US through Central and South America.
Condition Notes
Fair to Good. There is some separation of the barbs (zipper-like structure) near the tip and mid-vane, likely due to handling or natural wear before molting.
Interesting Facts
Barn Owls have the most sensitive hearing of any animal tested. Their ears are placed asymmetrically on their head, allowing them to triangulate the exact position of a mouse under snow or thick grass.
Ecological Role
Apex predator of small rodents. A single family of Barn Owls can consume over 1,000 rats or mice in a single nesting season, making them vital for natural pest control.
Similar Species
Short-eared Owl feathers are similar but usually show more distinct, heavy dark barring and a yellower/buff base color. Snowy Owl feathers are much larger and lack the warm tawny speckling.
