Abstract: The sex ratios of Nyctalus noctula, N. leisleri and N. lasiopterus were studied in North-East Hungary between 1994 and 2006. Significant seasonal changes were found in the sex ratios of N. noctula and N. leisleri. N. noctula females were not present during nursing time, which means that the species do not form maternity colonies in the region. Females were observed in the spring and autumn which suggests considerable migration. In the cases of N. leisleri and N. lasiopterus females were dominant during nursing time.
