The secrets of owls' near noiseless wings

Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence. A research group is working to solve the mystery of exactly how owls achieve this acoustic stealth -- work that may one day help bring “silent owl technology” to the design of aircraft, wind turbines, and submarines.
