"The secrets of owls' near silent wings has been revealed by scientists who could now use the technology to develop quieter aircraft. A new study has shown how the bird of prey's naturally evolved plumage gives the hunting advantage of 'acoustic stealth', allowing it to sneak up on targets. Research found that many owl species have developed feathers which can effectively eliminate the aerodynamic noise from their wings as they cut through the air."

Owls have the uncanny ability to fly silently, relying on specialized plumage to reduce noise so they can hunt in acoustic stealth. Researchers from the University of Cambridge, England, are studying the owl's wing structure to better understand how it mitigates noise so they can apply that information to the design of conventional aircraft.
