Popis: Work on animal personality, characterized by high behavioural repeatability, shows that animals exhibit limits to plasticity, with an individual’s range of variation only covering a portion of the range observed across the entire population. This work is particularly important for understanding the underlying genetic basis of behaviours. While research on behavioural repeatability has spanned many taxa, little work has focused on bats. Our objective was to determine if big brown bats (Eptesicus fuscus) exhibit moderate to high repeatability of different behavioural traits and if behavioural syndromes (among-individual correlations between behaviours) are present. Using a captive population, repeatability was assessed for aggression, exploration, and activity. Moderate repeatabilities were observed for all behaviours, indicating that individuals exhibit consistent behaviour over time. There were no significant correlations among behaviours. Future research aimed at assessing how changes in social structure impact behavioural repeatability will be valuable for understanding behavioural plasticity in social bat species.
