Inventario y estudio de los quirópteros en Quintos de Mora, Toledo

Abstract

This survey was carried out in June and July 2009 to identify the bat species and monitor their foraging activity in various habitats of Quintos de Mora´s farm, Toledo, Central Spain. Nine species were identified: Myotis daubentonii, Myotis escalerai, Myotis myotis/M. bythii, Eptesicus serotinus/E. isabellinus, Pipistrellus pipistrellus, Pipistrellus pygmaeus, Pipistrellus kuhlii, Hypsugo savii and Tadarida teniotis. We carried out 10 trapping sessions that allowed us to capture 28 individuals belonging to 7 species. Reproduction data were obtained from all species except M. daubentonii and M. escalerai. Ultrasound recordings gathered during 2,637 minutes provided 2,471 bat passes and 501 feeding buzzes. Total numbers of both bat passes and feeding buzzes were higher over water sites (ponds, reservoir) than in other habitats. Conifer plantations (Pinus pinaster) and Mediterranean macchia were respectively the most and the least used habitats by bats. All species were recorded in more than one habitat, although some of them (M. myotis/M. blythii, M. daubentonii, E. serotinus/E. isabellinus and T. teniotis) were not located in all habitat types. P. kuhlii were the most frequently recorded bats (54,8% of bat passes and 60,3% of feeding buzzes belonged to this species) and they were more and less frequently recorded in conifer plantations of Pinus pinaster and Quercus faginea respectively.
