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 Kingfisher
普通翠鸟（Alcedo atthis）— 广泛分布于欧亚大陆和非洲的亮蓝橙色鸟类。栖息于溪流和池塘旁，以鱼类为食。
