The Schreibers’ bent-winged bat (Miniopterus schreibersii), listed as Vulnerable on the IUCN Red List, has undergone severe population declines in Europe. In Piedmont (NW Italy), at the northern edge of its range, it is rare. Following the capture of a post-lactating female of this species – possibly a transient individual – at the entrance of a mouse-eared bat (Myotis blythii and Myotis myotis) maternity site in late July 2022, we investigated its occurrence in the six maternity colonies of mouse-eared bats currently known in the region. We analysed photographic material collected between 2004 and 2025 during yearly colony censuses, focusing on identifying possible M. schreibersii adults and newborns based on their distinctive morphological traits. Photographs taken after the emergence of adult bats at dusk provided the first clear evidence of M. schreibersii reproduction in Piedmont: newborns, although few in number (1-4), were repeatedly documented at the Abbey of Staffarda, the Castle of Agliè, and the Fortress of Verrua Savoia. Detections suggested an increasing trend in the number of individuals. Their frequency, together with the large distances from the nearest maternity colonies of M. schreibersii outside the region, rules out the possibility that the presence of newborns was the result of occasional transport by mothers during temporary roost-switch events. The observed distribution pattern suggests a strategy in which small groups of breeding females integrate into large mouse-eared bat colonies rather than forming a single, larger nursery. The non-invasive photographic method used proved effective, and could be suitable to monitor this species in other areas where it is uncommon.
