On the Attack

We watched this owl make multiple attacks on rodents over the course of several days. What impressed us the most was the utter silence of the attacks. "Serrated feathers on the front edges of owl wings funnel air smoothly over the wings, reducing the noise of rushing air. Each wing has a scarflike, fringed back edge that prevents the abrupt air-pressure changes--and noise--produced by rigid wings." (Info from the Biomimicry Guild)
