Radio-tracking a Lesser horseshoe bat (Rhinolophus hipposideros) in Bavaria: an experiment to locate roosts and foraging sites

A b s t r a c t . A radio-tracking experiment with Rhinolophus hipposideros in southern Bavaria revealed a new roost of a colony and a first insight into the foraging areas of this species in the Alps. The radio-tracked female mainly foraged in mountainous forests using 7 different foraging areas in three nights. They were located at an average distance of 2.4 km (max. 3.6) from the roost.
