Studies on the feeding biology of Lesser Kestrel (Falco naumanni) have limited in Turkey. The aim of this study was tocontribute to the knowledge of its feeding ecology in arid areas. In this study, pellet compositions of Lesser Kestrel wereexamined. Compositions of 17 pellets of Falco naumanni were used in the study. 182 preys which belong to 8 differenttaxa were found in the diet composition. Insecta (f= 59.34%) and Arachnida (f= 37.36%) taxa were the main preys in thediet composition of Falco naumanni. Solpugidae (Arachnida) (f= 35.16%) had the high prey rate in the dietarycomposition. The significant ratio of members of Solpugidae was similar to the results of the other semi-arid and aridareas.
