Size Comparison
Habitat Comparison
Barn Owl
Open farmland, grasslands, and marshes. Nests in barns, church steeples, tree cavities, and purpose-built nest boxes.
Northern Fulmar
Open ocean and sea cliffs. Breeds on cliff ledges and grassy slopes on northern coastlines. Pelagic outside breeding season.
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.
Northern Fulmar
A nasal, cackling 'kak-kak-kak-kak' or grunting 'uh-uh-uh' at the nest and colony. Less melodic than petrels. In flight gives occasional single nasal calls.
Geographic Range & Migration
Barn Owl
The most widespread owl and one of the most widespread land birds, found on every continent except Antarctica.

About These Birds
Barn Owl
헛간올빼미는 어떤 올빼미보다 가장 비대칭적인 귀를 가지고 있어, 동물계에서 가장 정밀한 청각 위치 파악 능력을 지닙니다. 소리만으로 완전한 어둠 속에서 먹이를 잡을 수 있습니다. 헛간올빼미의 독특한 하트 모양 얼굴은 포물면 접시처럼 작용하여 소리를 어긋난 귀로 집중시킵니다.
Northern Fulmar
The northern fulmar is a long-lived seabird that can survive over 40 years. It defends its nest by projectile-vomiting a foul-smelling stomach oil at intruders, which can mat the feathers of predators and cause fatal loss of waterproofing. Fulmars have expanded their breeding range dramatically southward over the past two centuries.
