About These Birds
Asian Crested Ibis
55–77 cm. White overall; bare red facial skin; long drooping nape plumes; pinkish wash in breeding. Endangered; reduced to near-extinction by 1981 (7 individuals in Japan) but recovered through captive breeding to thousands. Resident Japan, China, Korea; feeds on fish and crustaceans in rice paddies.
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.
