Size Comparison
Habitat Comparison
角雕
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Roseate Spoonbill
Shallow coastal lagoons, estuaries, mangroves, and freshwater marshes. Nests in colonies in trees and shrubs.
Song & Call Comparison
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.
Roseate Spoonbill
Low, grunting and guttural croaking sounds at nesting colonies. Generally quiet. Alarm calls are softer croaks. Vocalizations lack melodic quality; purely functional colony sounds.
Geographic Range & Migration
角雕
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

About These Birds
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。
Roseate Spoonbill
The roseate spoonbill is the only spoonbill species in the Americas and one of the most striking wading birds in the Western Hemisphere. Like flamingos, their pink color comes from carotenoid pigments in their crustacean prey. Nearly hunted to extinction for their plumes in the 19th century, they have recovered substantially.
