Bats hibernating in Kaunas Fortress, Lithuania
Kaunas Fortress is one of the largest bat hibernation sites known in northeastern Europe. Bat counts have been carried out there during two periods (19781995 and 2007). In 2007, 52 underground and semi-underground roosts belonging to seven forts and two bunkers were inspected. In all, 958 bats of 8...
