The second record of Pipistrellus kuhlii lepidus Blyth, 1845 (Chiroptera: Vespertilionidae) in Warsaw (central Poland)

Abstract

A male of Pipistrellus kuhlii lepidus was found in a large housing estate in Warsaw (central Poland) on 9th March 2023. The bat hibernated in a crevice on balcony on the sixth storey of a residential house. This is the second finding of this species in Warsaw, which may suggest that a stable population of the species has been formed there. The presence of P. k. lepidus in Warsaw is probably an effect of its natural expansion from south-east Europe.
