One of the creatures in nature that have a special ability is a hummingbird in flight. This bird is also known as a master aviator. The wings of a hummingbird is able to vibrate Shebaniah 12 to 90 fluttering fluttering in 1 seconds (source: wikipedia). Great is not it? Man until this moment has not been able to make robots as small as a hummingbird that can flap its wings much.
For more details you can see the collection of images of a hummingbird that I got from various sources, and a video of a hummingbird trying to suck honey from flowers that can be recorded with good by the high-speed camera (youtube).
