Popis:	Capsule In this region the diet is mainly cold-blooded prey, mostly insects such as beetles. Aims To describe the diet of this newly separated, poorly documented and endangered species. Method Diet was inferred from pellet analysis, collected during a single breeding and winter period in the steppe of the Crau. Results A total of 5409 prey were identified from 257 pellets. Vertebrates were seldom taken, except by adults (small passerines) during the fledgling period. High seasonal differences were found. Hymenoptera were largely consumed in autumn, Arachnida in autumn and winter, Orthoptera in summer and autumn and Lepidoptera larvae in winter and spring and by fledglings. Nevertheless, Coleoptera were ingested in large proportions all year round. Carabidae were the main prey in winter and Melolonthidae were especially important for adults during the nestling period, as were Cetoniidae for the fledglings. Conclusion Small mammals and small birds were less exploited in France and Spain (L. m. meridionalis)...
