About These Birds
Common Ostrich
非洲鸵鸟（Struthio camelus）— 世界上最大的鸟，栖息于非洲草原。虽然不能飞翔，但奔跑速度可达每小时70公里，产下世界上最大的蛋。
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.
