For many native Australian species, including microbats, tree hollows provide shelter, protection from predators and a stable microclimate for rearing young. We investigated the roosting habits of forest-dwelling microbats using nest boxes, which will move between multiple roosting sites as frequently as everyday. The factors driving roost-shifting behaviour are complex, but it is possible that reduced roost availability could influence social structure, parasitism and reproductive success. Our lack of understanding is largely due to the difficulty of simultaneously monitoring many bats in more than one roost without excessive disturbance of roosting sites. To overcome this problem we used implantable Passive Integrated Transponder (PIT) tags and a network of tag readers to remotely monitor the movement of individual bats using nest boxes. Using this technology we were able to continuously monitor roosting behaviour in a population of approximately 350 Gould’s wattled bats (Chalinolobus gouldii) for 18 months. From this data we found evidence of a female-centred social structure and some evidence for resource-guarding by males during the breeding season. We are currently investigating the influence of roost box microclimate on microbat energetics, water turnover and patterns of torpor, the implications of which are likely to inform the use of artificial nesting boxes as management tools.
