Size Comparison
Habitat Comparison
Common Starling
Open countryside, farmland, parks, and urban areas. Forms enormous communal roosts in winter, especially in urban environments.
부채머리독수리
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.

A complex mimic: rattles, whistles, clicks, and squeaks mixed with imitations of other birds. Song is a continuous medley. Also gives harsh 'scheer' alarm and chattering.
부채머리독수리
Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.

Native to Europe, western Asia, and North Africa. Introduced to North America, South Africa, Australia, and New Zealand.
부채머리독수리
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.
