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.

About These Birds
Barn Owl
メンフクロウはあらゆるフクロウの中で最も非対称な耳を持ち、動物界最高の聴覚的方向定位能力を誇る。完全な暗闇の中でも音だけで獲物を捕まえることができる。特徴的なハート形の顔は放物線状の皿として機能し、ずれた両耳に音を集める。
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.
