Nenhum
Barn Owl
Open farmland, grasslands, and marshes. Nests in barns, church steeples, tree cavities, and purpose-built nest boxes.
Gavião-real
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.
Gavião-real
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.
Gavião-real
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.
Gavião-real
The harpy eagle is among the most powerful raptors in the world, with talons as large as a grizzly bear's claws. It is the national bird of Panama. Deforestation poses the greatest threat to this species, as each breeding pair requires a vast territory of undisturbed forest.
