Small birds often fly long distances using a technique in which short bursts of flapping are alternated with intervals in which the wings are folded against the body This is a flight pattern known as bounding or flap bounding flight When the bird s wings are folded its trajectory is primarily ballistic with a small amount of body lift The flight pattern is believed to decrease the energy required by reducing the aerodynamic drag during the ballistic part of the trajectory and to increase the efficiency of muscle use.
