The aim of the study was to determine whether raccoons pose a threat to bats wintering in the Nietoperek nature reserve, one of the largest hibernation sites in Central Europe. In the winter of 2016–2017, 67 raccoon scats were collected in one of the main underground corridors in the reserve. It was confirmed, with the use of molecular methods, that the scats belonged to raccoons. Raccoon prey was identified based on the features of skulls, jaws or hair found in the scats. Analysis of the determinable remains indicates that bats (including Daubenton's bat/Natterer's bat/Brandt's bat M. daubentonii/nattereri/brandtii, Natterer's bat Myotis nattereri, greater mouse-eared bat Myotis myotis, brown long-eared bat Plecotus auritus) made up the largest percentage of raccoon diet (96%).
