Aerial hawking and landing: approach behaviour in Natterer's bats, Myotis nattereri (Kuhl 1818)
We compared the flight and echolocation behaviour of a vespertilionid bat ( Myotis nattereri ) approaching a large stationary or a small moving target. Bats were trained to either land on a landing grid or to catch a moving tethered mealworm. When closing in on these two targets, the bats emitted gr...

We compared the flight and echolocation behaviour of a vespertilionid bat ( Myotis nattereri ) approaching a large stationary or a small moving target.

Therefore, the information collected in buzz II does not guide the bats to the target. The relevant part of the approach phase to reach the target ends with buzz I.
