Реферат:	eng: Diets of the Long-eared and Short-eared Owls, closely related species with overlapping ranges, have been studied in the south of Western Siberia (the Baraba Lowland) by analyzing bone remains in pellets. The results show that both species in the south of the Baraba Lowland employ similar strategies of food resource use, which, however, differ in some aspects. In the Short-eared Owl, the hunting range is apparently more restricted. During the nesting period, these birds occupy relatively moist habitats along riverbanks and protect their hunting grounds. The Long-eared Owl nests in mainly mesic habitats, in forest outliers, and can supplement its diet with shrews (Sorex) and steppe rodent species. The diets of both species largely consist of murine rodent species that are dominant or subdominant in the small mammal community of the Baraba forest-steppe. Seasonal and interannual variations in the food spectra of both species have been revealed. © 2013 Pleiades Publishing, Ltd.
