Artificial light at night poses a serious threat to wildlife, particularly to nocturnal species. Bats that roost in urban areas during the day but forage in surrounding natural habitats at night face the dilemma of commuting through artificially lit environments on their way to dark foraging grounds. Such illumination may force bats to take energetically costly detours, threatening colonies by disconnecting them from areas of high prey density. Here, we studied commuting greater mouse-eared bats (Myotis myotis), a…
