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 Myna
家八哥（Acridotheres tristis）— 原产于南亚，已被引入世界各地的强适应性椋鸟科鸟类。黄色嘴和眼周黄色裸皮为特征。
