Song & Call Comparison

Common Ostrich
Male produces a surprisingly deep, resonant booming roar — remarkably lion-like. Also gives whistling and hissing sounds. Females and chicks emit softer grunts and squeaks.
Geographic Range & Migration

Sub-Saharan Africa. Formerly also found in the Middle East and parts of Asia. Farmed worldwide.

About These Birds
白头海雕
The bald eagle is the national bird and symbol of the United States. Once endangered due to DDT pesticide use, it made a remarkable recovery and was removed from the endangered species list in 2007. These powerful raptors build the largest tree nests of any bird, some weighing over two tons.
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。
