Habitat Comparison
European Goldfinch
Open woodland, orchards, gardens, parks, and weedy fields with seed-bearing plants. Common at garden bird feeders.
オウギワシ
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison

A liquid, tinkling 'swit-swit-swit' in flight and a melodic twittering song. Flocks produce a bright jingling chorus. Male song is a sweet repetitive warble incorporating the flight 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.

オウギワシ
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.
