Tomorrow Today # Soft and silent – Owls' wings provide an example for airplanes # 08.06.2009

No other bird flies as quietly as an owl. Their wings have special characteristics that make this possible. As a result, they are able to approach prey so quietly that they go unnoticed. Another reason evolution has favored their stealth is that they use their keen ears to hunt. Noisy flapping would make them unable to use their outstanding hearing to find their meals.
