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.
Australasian Grass-owl
The Australasian Grass-owl is a barn owl relative found in open grasslands and marshes from Australia and New Guinea to parts of Asia. Weighing about 382g with a wingspan of 62.5cm, it has a pale heart-shaped facial disc and long legs suited for hunting through grass. It hunts rodents and other small mammals at night.
