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.
European Roller
因求偶时的翻滚飞行而得名。欧洲唯一的佛法僧科鸟类。种群数量下降。
