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.
