Size Comparison
Habitat Comparison
Belted Kingfisher
Rivers, streams, lakes, ponds, estuaries, and coastlines with clear water and suitable perches. Nests in burrows dug into earthen banks.
角雕
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison
Belted Kingfisher
A loud, rattling 'klee-klee-klee-klee' — mechanical and penetrating. Given in flight along rivers. Also a harsh 'kekekek' near nest. Far louder than Common Kingfisher.
角雕
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
Belted Kingfisher
North America from Alaska and Canada to Central America and the Caribbean. Northern populations migrate south in winter.
角雕
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

About These Birds
Belted Kingfisher
The belted kingfisher is unusual in that the female is more colorful than the male, sporting an additional rufous belly band. These noisy birds announce their territory with a distinctive rattling call. They excavate nesting burrows up to 2.4 meters deep into riverbanks using their heavy bills.
角雕
角雕是美洲最大的猛禽之一，翼展可达224厘米。头部具灰白色双羽冠，体羽黑白对比分明，爪极为强大有力。分布于墨西哥至玻利维亚的热带低地雨林，以树栖哺乳动物为主食，包括树懒和猴子。飞行速度快，是雨林顶级捕食者。
