Size Comparison
Habitat Comparison
Barn Owl
Open farmland, grasslands, and marshes. Nests in barns, church steeples, tree cavities, and purpose-built nest boxes.
Snowy Owl
Arctic tundra for breeding. Winters in open habitats resembling tundra, including prairies, airports, shorelines, and agricultural fields.
Song & Call Comparison
Barn Owl
An eerie, drawn-out rasping shriek 'shreeeeee' — not a hoot. Also gives hissing, snoring, and bill-snapping when disturbed. Chicks call with a persistent rasping hunger call.
Snowy Owl
Male gives a deep booming hoot 'hooooo' and a rising 'hoo-hoo' series. Also barks sharply when alarmed. Quieter than many owls; silent during long Arctic winter hunts.
Geographic Range & Migration
Barn Owl
The most widespread owl and one of the most widespread land birds, found on every continent except Antarctica.
Snowy Owl
Circumpolar Arctic for breeding. Irruptive winter movements bring birds south to the northern United States, Europe, and Asia.

Pale pinkish hooked bill nearly concealed by the facial disc
Snowy Owl
Adult males are almost entirely white. Females and immatures have dark brown barring and spotting. Yellow eyes and fully feathered feet.
Dark hooked bill mostly hidden by dense facial feathering
About These Birds
Barn Owl
The barn owl has the most asymmetrical ears of any owl, giving it the finest auditory localization ability in the animal kingdom. It can catch prey in complete darkness using sound alone. The barn owl's distinctive heart-shaped face acts as a parabolic dish, funneling sound to its offset ears.
Snowy Owl
The snowy owl is the heaviest North American owl and one of the most charismatic Arctic birds. Unlike most owls, it is largely diurnal, necessitated by the continuous daylight of Arctic summers. Snowy owl irruptions — periodic mass southward movements — are tied to lemming population cycles.
