Warmer winters may lead to changes in the hibernation behaviour of bats, such as the barbastelle Barbastella barbastellus, which prefers to hibernate at low temperatures. 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 t...

Light is necessary for life, but prolonged exposure to artificial light is a matter of increasing health concern. Humans are exposed to increased amounts of light in the blue spectrum produced by light-emitting diodes (LEDs), which can interfere with normal sleep cycles. The LED technologies are relatively new; therefore, the long-term effects of e...

The paper presents breeding records of the barbastelle (Barbastella barbastellus) from the whole current territory of Poland, both published data from papers and conference abstracts, and unpublished data collected by the authors. Up to 1999, known locations of maternity colonies and sites where young or lactating females had been caught, were assi...

In contrast to extensive research on optimal foraging in birds, the proximate mechanisms by which birds estimate the properties of nuts or seeds have not been well studied. Using slow-motion video-recording and experiments with modified peanuts presented to birds in their natural habitat, we explored these issues in a wild population of the Mexican...
Conference Paper
Full-text available
Background / Purpose: We conducted field experiments to test whether Mexican jays use “dynamic touch” to perceive the weight of elongated peanuts. These peanuts were designed so that “perceived” moments of inertia are different depending on the location of the grip. Main conclusion: Our results suggest that weight perception in Mexican jays is...

Numbers of wintering Natterer’s bats Myotis nattereri (Kuhl, 1817) and Daubenton’s bats M. daubentonii (Kuhl, 1817) were monitored at seven study sites (three single large hibernacula and four groups of roosts) in central Poland. The longest monitoring period was 1987–2009, the shortest - 1999–2009. The aim of the study was to find out if the numbe...

In order to identify population trends in Barbastella barbastellus in Poland we summarised results of long-term winter bat counts conducted between 1985 and 2004 in seven of the most important hibernacula of the species. The results show an upward trend in four of the sites while in the remaining four no trend was found. The numbers of barbastelles...

This study on the foraging areas of bats was conducted on 64 transects (2 km long) in different habitats and urban zones in central Poland. Relative bat densities in the city (Warsaw) were only slightly lower than in comparable habitats outside the city. The maximum densities of foraging bats were noted in wooded and riparian habitats (in the city...
