The largest number of aberrant colouration cases was recorded during the hibernation period in the Nietoperek bat reserve, western Poland (0.016% individuals with albinism). In 2014, five individuals with partial albinism and one flavistic bat were found there. Proportion of individuals with albinism varied from 0.05% in the case of M. nattereri, 0.02% in the case of M. daubentonii and only 0.007% in the case of M. myotis. During the studies on bat swarming in the Tatra Mountains one case of leucistic whiskered bat was recorded which accounts for 0.016% out of over 5,900 representatives of this species that were caught. Aberrant colouration in bats is rarely recorded in Poland and it is not associated with any particular geographical region. Higher probability of observing atypically coloured individuals occurs in large populations of bats.

At present we know 9 sites (areas of occurrence) of this species in this area. These are the following squares according to the UTM grid: WS62, WS63, WS70, WR97, XR36, XR37, XR38, XR39, XR59, XR67 and XR77. There were recorded in total 22 underground winter and spring shelters and 5 summer shelters. The breeding colonies of R. hipposideros as well as the more numerous winter colony are known in Góry Opawskie only. In the remaining regions in the shelters were recorded only 1-2 individuals per control.

The cases of mortality were confirmed for 7 bat species: Vespertilio murinus, Eptesicus nilssonii, Eptesicus serotinus, Pipistrellus pipistrellus, Pipistrellus pygmaeus, Pipistrellus nathusii and Nyctalus noctula. 5 species were recorded in Pobrzeże Gdańskie (Gdańsk Coast) region, 3 species on Pobrzeże Szczecińskie (Szczecin Coast) and one species in each of the remaining regions. Pipistrellus nathusii was found in three regions and Vespertilio murinus and Nyctalus noctula in two regions.

The species is also known for its large annual fluctuations in the number of wintering individuals, so inference about population trends should be based on long-term data. Prior to 2005, analyses indicated stable or even increasing barbastelle population in Poland. We analysed the results of 13 winter bat counts (2005-2017) of the species from 15 of the largest hibernacula, and additional site of 47 small bunkers, in Poland. The total number of wintering individuals remained stable during the study period, because the barbastelle is not a long-distance migrant, this likely reflects the national population trend. On the basis of mean winter air temperatures we divided the country into four thermal regions. Analyses of barbastelle abundance in hibernacula in the four regions revealed a 4.8% annual mean increase in numbers in the coldest region, where mean winter temperatures were below-2˚C, annual mean declines of 3.3% and 3.1% in two warmer regions of western Poland, but no trend in the region of intermediate mean winter temperatures of between-1˚C and-2˚C. Overall, there was a significant, but weak, negative correlation between the abundance of hibernating individuals and the mean winter temperature. On the other hand, the number of individuals hibernating in small bunkers increased, even though the site was located in one of the warm regions. The results indicate a warming climate will likely reduce the use of large, well-insulated winter roosts by species that prefer colder conditions-and that this is already

Here we present the first observation of grass snake Natrix natrix in the galleries of Cerambyx cerdo. We recorded three grass snake individuals basking and hiding inside the C. cerdo galleries. We suggest the presence of this beetle species may create new environmental niches and improve habitat quality for snakes and other vertebrates.
