Long distance migration of female Leisler’s bat (Nyctalus leisleri) from Italy to Poland


The routes followed by migratory bat populations occurring in Italy are practically unknown. We herewith report on the capture of a female Leiskler’s bat Nyctalus leisleri occurred in Poland, Wielkopolska province (Greater Poland), district Ostrzeszów, in a forest near the village of Jesiona. The specimen, caught on 5 August 2012, had been previously (23 September 2010) banded in Italy in the Nature State Reserve of Pian degli Ontani (Cutigliano, Pistoia Province, Italy, 44° 06’ 27" N, 10° 41’ 33" E; ring code WWF-ITALY C0524). The minimum straight distance between the two sites is ca. 960 km. This record is the first that proves the existence of migration in Italian populations of N. leisleri and shows that a long NE-SW migration route – one of the longest recorded in Europe by N. leisleri – is followed. The observation remarks once again the importance of a large-scale, trans-national planning of bat conservation.
