Pellet analyses were used to identify small
mammal species in the diet of this owl species in order to reveal its
ecological role. In this study, 706 pellets of Asio otus were collected from 3 different localities in Fatih
Natural Park between February and March 2014. Pellets were dissolved by using
3% NaOH solution and then bones were dehydrated and identified. The aim of this
study 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 were
detected as the result of analysis. These individuals were identified to
belonging to 12 mammal species (Crocidura
suaveolens, Suncus etruscus, Microtus hartingi/lydius, Microtus levis, Microtus sp., Cricetulus migratorius,
Mesocricetus brandti, Apodemus sp., Apodemus sylvaticus, Apodemus
whitherbyi, Mus macedonicus, and Meriones tristrami) from 3 families and
8 genera. Microtus hartingi/lydius,
which is known as agricultural pest, was dominant in the diet of Asio otus. When diversity of mammal
species within the food composition was examined, Asio otus nesting in forest was found to primarily prefer
agricultural and steppe areas, and was also found in woody and bushy areas. The
use of Asio otus can be taken into
consideration when dealing with rodent species known as agricultural pests.
