Size Comparison
Habitat Comparison
オウギワシ
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Hawfinch
Deciduous and mixed woodland, orchards, parks, and large gardens with mature fruiting trees.
Song & Call Comparison
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.
Hawfinch
A sharp, metallic 'tsick' call — the primary vocalization and often all that's heard. Song is a thin, reedy warble. Generally inconspicuous vocally despite its striking appearance.
Geographic Range & Migration
オウギワシ
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.
Hawfinch
Europe, North Africa, and western and central Asia. Partially migratory, with northern populations moving south in winter.
