N2  - Pellet analyses were used to identify smallmammal species in the diet of this owl species in order to reveal itsecological role. In this study, 706 pellets of Asio otus were collected from 3 different localities in FatihNatural Park between February and March 2014. Pellets were dissolved by using3% NaOH solution and then bones were dehydrated and identified. The aim of thisstudy was to determine mammal composition in the diet of Asio otus inhabiting Fatih Natural Park of Yozgat Province, Turkey.Residues of bone from 1293 individuals/preys corresponding to 42377.41 g biomass in total weredetected as the result of analysis. These individuals were identified tobelonging to 12 mammal species (Crocidurasuaveolens, Suncus etruscus, Microtus hartingi/lydius, Microtus levis, Microtus sp., Cricetulus migratorius,Mesocricetus brandti, Apodemus sp., Apodemus sylvaticus, Apodemuswhitherbyi, Mus macedonicus, and Meriones tristrami) from 3 families and8 genera. Microtus hartingi/lydius,which is known as agricultural pest, was dominant in the diet of Asio otus. When diversity of mammalspecies within the food composition was examined, Asio otus nesting in forest was found to primarily preferagricultural and steppe areas, and was also found in woody and bushy areas. Theuse of Asio otus can be taken intoconsideration when dealing with rodent species known as agricultural pests.
