Size Comparison
Habitat Comparison
Barn Owl
Open farmland, grasslands, and marshes. Nests in barns, church steeples, tree cavities, and purpose-built nest boxes.
オウギワシ
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.
オウギワシ
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.
オウギワシ
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.
