Abstract
Bats are nocturnal animals that use echolocation to navigate their environment. As auditory specialists, bats also developed a complex array of communication signals. We can utilize communication calls to comprehend these animals' behavioral states and social structure. Carollia perspicillata is highly social mammal that has been used in a wide array of laboratory studies, from disease transmission to neuroscience. We aim to explore how C. perspicillata female bats choose between a known or novel bat, with acoustic analysis to determine group differences. We hypothesized that while most females will choose to roost with a known conspecific, some individuals will choose the novel bat, supporting the fission-fusion model, formation of new roosts, and inter-species roost-sharing. Our data show that captive bats spend more time with roostmates than with strangers, whereas wild bats show no preference. To our knowledge, this is the first study to examine differences in social behavior between wild-caught and captive-born populations of C. perspicillata, which can inform us on how reduced social variation and reduced genetic variability affect bat welfare and social behavior.
