abstract

In 1984–2000, observations of wintering bats in underground cavities located in Chernivtsi, Ivano-Frankivsk, Khmelnytskyi and Ternopil regions were conducted. A total of 24 underground cavities of both natural and artificial origin were surveyed. In 18 of them, hibernating bats were found belonging to 9 species: R. hipposideros, M. myotis, M. bechsteinii, M. daubentonii, M. dasycneme, M. mystacinus, P. auritus, and B. barbastellus. Most of the specimens among wintering cave-dwelling bats were R. hipposideros and M. myotis. No abundant (more than 300 individuals) wintering colonies were found, although such colonies were mentioned earlier for Western Ukraine. Fragmentation of populations is a result of increase of human influence. Small colonies attract less attention of humans and predators thus they have more chances for successful wintering. As of 2000, 3 new underground shelters of key importance were discovered in Chernivtsi, Khmelnytskyi, and Ternopil regions. Some individuals were marked by rings in order to study their migration routes. In total, 89 bats were ringed in Verteba, Vitrova, and Zbruchanska caves. Subsequent catches testified the association of bats with these wintering shelters.
