Abstract
This study on the foraging areas of bats was conducted on 64 transects (2 k m long) in different habitats and urban zones in central Poland. Relative b at densities in the city (Warsaw) were only slightly lower than in comparab le habitats outside the city. The maximum densities of foraging bats were n oted in wooded and riparian habitats (in the city respectively 2.0 and 1.0 records/100 m per count; outside of the city - 1.8 and 1.5 records/100 m pe r count). Open areas were the least frequently visited by foraging bats. Bu ilt-up areas outside the city were characterized by higher densities than c ity built-up areas. The percent of Eptesicus serotinus records was highest in the central zone (about 66%) and decreased with the distance from the ci ty centre. The main foraging areas of Nyctalus noctula were distributed in riparian habitats of all zones. Pipistrellus nathusii and Myotis spp. were more frequent in a landscape less transformed by human activity. Tree cover within a foraging site was the most important factor influencing bat densi ty.
