Description

ABSTRACT. We investigated colonies and reproductive patterns of adult female eastern pipistrelles, Pipistrellus subflavus, in Indiana during the non-hibernation season in 1999-2000. Females began to form small colonies (range, 1-8 individuals) during early May, and parturition occurred during late June and early July (sex ratio of young = 1:1). Young pipistrelles began to fly during middle to late July. Colonies of adult females began to disband soon after the young became volant. Alter leaving colonies, the adult females roosted singly tier the remainder of the summer, and then moved to hibernation sites from late August through September. This study is the first detailed description of tree colonies and reproductive patterns of eastern pipistrelles roosting in natural structures.
