About These Birds
Black-faced Spoonbill
The Black-faced Spoonbill is a large, elegant wading bird with all-white plumage, a distinctive spatula-shaped black bill, and black facial skin around the eyes. It is critically endangered and among the rarest spoonbills in the world, breeding on rocky islets off the Korean Peninsula and wintering mainly in Taiwan, Hong Kong, and Vietnam. It feeds by sweeping its spoon-shaped bill through shallow water to capture fish, crustaceans, and aquatic invertebrates.
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.
