Shallow coastal lagoons, estuaries, mangroves, and freshwater marshes. Nests in colonies in trees and shrubs.

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.

About These Birds
オウギワシ

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.
