Abstract
In the period 2004-2006 a sampling of bats took place in Aragon. Traps were set in 47 forests and 67 potential shelters were inspected. Mist nets, harp traps, ultrasound detectors and video cameras were used. A total of 1197 specimens, belonging to 24 species, were captured; 529 records were obtained and the presence of at least 120 breeding colonies was identified (32 of them the common pipistrelle (Pipistrellus pipistrellus, 110 records and 30 breeding colonies), Savi’s pipistrelle (Hypsugo savii, 63 records and 11 colonies) and Kuhl’s pipistrelle (Pipistrellus kuhlii, 48 records and 13 colonies). Reproduction data have been found for all species except for Myotis capaccinii, Myotis cf. nattereri, Nyctalus lasiopterus, Nyctalus leisleri and Eptesicus serotinus. The species found can be divided into four large groups: one of general and continuous distribution (P. pipistrellus, P. kuhlii, H. savii, E. serotinus and P. austriacus), another of general but discontinuous distribution (R. ferrumequinum, R. hipposideros, R. euryale, M. myotis, M. blythii, M. escalerae, M. emarginatus, M. daubentonii, P. pygmaeus, M. schreibersii and T. teniotis), a third of forest species, which were found only in some of the extensive wooded areas (Pyrenees, Moncayo and the south of Teruel: M. mystacinus, M. cf. nattereri, P. auritus, B. barbastellus, N. lasiopterus and N. leisleri) and finally two very rare species in the region (M. capaccinii and P. macrobullaris). The distribution of these species in Aragon is shown and their status in relation to data obtained and the bibliography is reviewed.

Summary
En el período 2004-2006 se ha realizado un muestreo de los quirópteros de Aragón. Se ha trampeado en 47 bosques y se han inspeccionado 67 refugios potenciales. Se han encontrado datos de reproducción para todas las especies identificadas salvo Myotis capaccinii, Myotis cf nattereri, Nyctalus lasiopterus, Nyctalus leisleri y Eptesicus serotinus. Las especies halladas se reparten según cuatro patrones: uno de distribución general y continua (P. pipistrellus, P. kuhlii, H. savii, E. serotinus y P. austriacus), otro de distribución general pero discontinua T. teniotis), otro de especies forestales, presentes únicamente en algunas de las grandes manchas boscosas (Pirineos, Moncayo y sur de Teruel: M. mystacinus, M. cf nattereri, P. auritus, B. barbastellus, N. lasiopterus y N. leisleri) y el último con dos especies de presencia muy restringida en la región (M. capaccinii y P. macrobullaris). Se muestra la distribución de estas especies en Aragón y se comenta su estado de conservación en función de los datos obtenidos en este trabajo y la bibliografía.
