About These Birds
Barn Owl
The barn owl has the most asymmetrical ears of any owl, giving it the finest auditory localization ability in the animal kingdom. It can catch prey in complete darkness using sound alone. The barn owl's distinctive heart-shaped face acts as a parabolic dish, funneling sound to its offset ears.
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。
