Abstract: Common pipistrelles (Pipistrellus pipistrellus) congregate in mass-hibernacula, sometimes with hundreds to thousands of individuals. In the urban environment, these hibernacula are often situated in crevices and other spaces in buildings with poor insulation.

Abstract: This study investigates the relationship between outdoor temperatures, periods of prolonged precipitation and the numbers of brown long-eared bats (Plecotus auritus) in hibernacula during the annual bat census.

Abstract: The numbers of hibernating bats in the Voorberg-Jezuïetenberg marl quarry complex, southwest of Maastricht, were monitored between 1987 and 2020 by means of annual counts at the turn of the year.
