About These Birds
White-shouldered Ibis
75–80 cm. Large; dark brown with white shoulder patch; bare red facial skin. Critically Endangered; fewer than 250 birds known. Restricted to lowland Mekong forests of Cambodia, Vietnam, and Myanmar. Threatened by forest clearance and hunting; one of Asia's rarest birds.
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.
