The research done on bat flight has increased the knowledge about bat flight and the corresponding aerodynamic phenomena in great extent. In the mid seventies and eighties, the first kinematic studies by Norberg (1976a,b) and Aldridge (1986, 1987) were performed with the use of high speed cameras and made it possible to analyze the kinematics of bat flight in great detail. These studies were first performed in _ight corridors, later followed by measurements in windtunnels (Busse von, 2011). This made it possible to measure over a range of flight speeds, which shows a gradual change in kinematics when _ight speed is increased. Aerodynamic measurements were the next step in bat flight research and gave a better insight in the vortex structure of bat _ight both onwing (Muijres et al., 2008) and in the wake (Hedenstrom et al., 2007, 2009; Johansson et al., 2008).
