Résumé :	Several males of Great Bustard were recorded in southwestern France (Pyrenees-Atlantiques and Gers) in summer 2009. An analysis of available data shows a more regular occurrence of this species in the past in southwestern France after cold spells (individuals originating from central Europe) but also in summer as it was the case in 2009. The summer records fit the postnuptial dispersal of Great Bustard males originating from the Iberian Peninsula. These males disperse northwards alter the spring coutship period and return southwards at the end of summer.
