The Secrets of Owls' Near Noiseless Wings

"silent owl technology" may help to design wind turbines in the future.

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 working to solve the mystery of exactly how owls achieve this acoustic stealth will present their findings at the American Physical Society’s (APS) Division of Fluid Dynamics meeting, held Nov. 24 — 26, in Pittsburgh, Pa. — work that may one day help bring “silent owl technology” to the design of aircraft, wind turbines, and submarines.
