Bat study: capture and radio-tracking

The target of this study was to define the hunting areas used by the greater mouse-eared bat (Myotis myotis). It is part of the impact assessment for two wind farm projects in the municipality of Houffalize. Our mission was very clear: capture bats on their hunting grounds, equip the captured greater mouse-eared bats with a VHF tag and follow them days and nights, with radio-tracking technics. During the 9 capture sessions, 4 males of greater mouse-eared bat were caught and equipped with a transmitter. The intensive radio-tracking work allowed us to find 3 daytime roosts and to identify the forest areas used as hunting sites.
