Size Comparison
Habitat Comparison
흰머리수리
Large bodies of open water including coasts, rivers, and lakes with abundant fish and old-growth trees for nesting.
부채머리독수리
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison

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

North America from Alaska and Canada through the contiguous United States to northern Mexico.
부채머리독수리
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.
