Size Comparison
Habitat Comparison
Barn Owl
Open farmland, grasslands, and marshes. Nests in barns, church steeples, tree cavities, and purpose-built nest boxes.
角雕
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
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.
角雕
Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.
Geographic Range & Migration
Barn Owl
The most widespread owl and one of the most widespread land birds, found on every continent except Antarctica.
角雕
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

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.
角雕
角雕是美洲最大的猛禽之一，翼展可达224厘米。头部具灰白色双羽冠，体羽黑白对比分明，爪极为强大有力。分布于墨西哥至玻利维亚的热带低地雨林，以树栖哺乳动物为主食，包括树懒和猴子。飞行速度快，是雨林顶级捕食者。
