Habitat Comparison
Belted Kingfisher
Rivers, streams, lakes, ponds, estuaries, and coastlines with clear water and suitable perches. Nests in burrows dug into earthen banks.

Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.

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