It flies from Pistoia to the outskirts of Florence, then moves to Empoli and the urban hinterland: it is the first Italian bat equipped with a GPS tracker. The specimen is a male equipped by CNR researchers with an ultralight GPS. The tracking device, a plate with a small antenna and built-in geolocator, weighs about one gram and is glued to the animal's back with a surgical, non-toxic glue. The battery lasts between 40 and 60 days, and after that time, the glue dries and the backing comes off. This method means that the bat does not have to be recaptured to remove the device, reducing the stress load on the animal. The data are collected and sent automatically about once/twice a day, and can be downloaded simply by logging on to the site and entering the GPS code, provided by the German Max Planck Institute. Overall, the information obtained allows the research team to reconstruct the path taken by the animal. The work is part of a larger project to monitor migratory species (“ICARUS Bats”) in order to study their ecology, behavior and movements across several European countries.
