Wind turbines, helicopters, and other devices that use rotors have a big noise problem, but the solution may come from a not-so little bird. Scientists from Chiba University in Japan and Shanghai Jiao ...

AMES, Iowa – Anupam Sharma pulled an accordion folder from the bookshelf above his Iowa State University desk. Inside was the carefully collected and preserved wing of a short-eared owl. Here, he said ...

Owls produce negligible noise while flying. While many studies have linked the micro-fringes in owl wings to their silent flight, the exact mechanisms have been unclear. Now, a team of researchers has ...

Every owl fancier has a story of the first time they heard an owl — or, rather, didn’t hear one. It’s unforgettable to see an enormous bird, whose wingspan can reach more than six feet, slipping ...

The ability of birds to react to choppy gusts is leading aeronautical engineers to explore the concept of hinged wings on planes and drones. The responses to wind of a barn owl named Lily were studied ...

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 ...

This is a lousy photo of a Great Horned Owl, except that it shows the shape of the wings well. The bird had flushed, and was flying away from me. You can see that the wings are broad all the way to ...

The micro-fringes on owl wings effectively suppress the noise while maintaining the aerodynamic performance of the wings comparable to that of a wing without the fringes. Owls are fascinating ...
