Aerial-hawking bats adjust their use of space to the lunar cycle

We tracked adult Nyctalus noctula in July 2015 using Robin GPS loggers (CellGuide, Israel). Bats were taken from their artificial roosting boxes in the morning and loggers were attached with Sauer Hautkleber, then bats were placed back in their roosting boxes, which were located in a pine stand near Prieros / Germany. Loggers recorded GPS positions every 15 seconds. We retrieved useful GPS data for 9 animals. Data was analysed with respect to space use and the influence of moonlight on habitat choice of bats.
