Keywords: pond bat, habitat, distribution, migration, quantity
The pond bat hibernacular and summer distribution over the territory of Saint-Petersburg and Leningrad Region was investigated. The bat counts were carried out in the cave hibernacula in 2007–2009. 32 caves were examined. Summer distribution was studied in 2009 by means of ultrasonic detector D:200. The data were processed in ArcGIS system. During hibernation season, 992 to 1 302 pond bats were sighted. 156 pond bats were detected in summer habitats. 67 migrating pond bats were detected in autumn. The pattern of the distribution dynamics, the time of settlement in hibernacula, the migration routes and congestions, specifics of summer habitats were explored. An estimation of the total pond bat numbers is discussed.
