The Giant Noctule (Nyctalus lasiopterus, Schreber 1780) is one of those difficult forest species and probably the European rarest and least studied of them. However the development of bat detectors and of radio-tracking techniques have allowed increasing the knowledge on this elusive species. ntil recently, with the exception of a few occasional records of individuals, the Giant Noctule was mainly known from Spain and Central Europe where breeding colonies were located. We present here its distribution in France, where a colony of post-lactating females was found in June 2012. This record is the first documented data for Western Europe, north of the Pyrenees. %> internal-pdf://1435963042/Duborg_et_al_2013.pdf
