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 Kestrel
The common kestrel is Europe's most abundant falcon, famous for its ability to hover motionless in the wind while scanning for prey. Research has shown kestrels can see ultraviolet light, allowing them to detect vole urine trails that reflect UV. The species has adapted remarkably well to urban environments.
