Gaukelflug
As Gaukelflug is at butterflies and some birds of prey - especially the ordinations - called a back-and herschwenkende type.
During the consecration, the flight of jugglers, which takes place with the wings held slightly upwards at a low height above the ground, is used to search for prey close to the ground. The prey is surprised and on the ground from a short distance resorted, but some can Harriers also beat usually also scared small birds by rapid body turns in the air. This type of flight is very low in energy and uses the wind at low altitude. A disadvantage of the trickery flight is that an escaped prey cannot be tracked fast enough.
In the case of butterflies , the flight of flies is due to the shape of the wing, but it also makes it easier to find suitable flowers. In advertising, it often develops into a dancing flight for the couple.
