Take Off Signals Emitted by Myotis Mystacinus: Theory of Receivers and Modelling

  • B. Escudié
Part of the NATO ASI Science book series (NSSA, volume 156)


Since 1976, our group carried systematical annual experiments on Myotis mystacinus in very convenient sites: Montellier (Ain) France, 20 km N.E of LYON. During June 1980 (16/05/80) records were made of SONAR signals emitted by Myotis mystacinus during take off and the early part of flight. Bats were taking off from behind a shutter of an old barn (see fig. 1). We only register during this experiment the take off signals and the cruise ones emitted when the bat is flying to the microphone (16).
