How the Bat, Pipistrellus Kuhli, Hunts for Insects
Most studies on the insect catching behavior in bats describe either echolocation behavior or capture techniques and flight behavior. Only in a few laboratory studies have both behaviors been studied simultaneously. We were able to do this in the field following the development of a battery operated 6 flash strobe system, which could be synchronized with the sound recordings. This equipment is still very bulky and cannot be moved during a recording session. Therefore we concentrated our efforts on a bat species, which reliably hunted in one area and could therefore be easily photographed. In the village Gornije Okrug near Trogir in Yugoslavia we found a site where several Pipistrellus kuhli regularly hunted for insects near a street light. The data from 10 nights of recording are presented here.
