About These Birds
Southern Bald Ibis
79 cm. Glossy black with metallic sheen; bare pink facial skin; red bill and legs. Endemic to South Africa and Lesotho in mountain grasslands and escarpments. Vulnerable; feeds on insects and small vertebrates in short grassland. Colonial breeder on cliff ledges; at risk from pesticides and habitat loss.
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.
