Table 7. Foraging responses of radio-tagged Myotis nattereri at 6 church sites (n = 6 bats/site) and effect of short-term applications of acoustic deterrence at roosts inside churches.
Response variables were time of emergence, time of return to church after foraging, total time spent foraging, individual bat home range area (MCP), core foraging area (cluster core), and range span (distance from roost to furthest edge of cluster core foraging area).
