Title: Small mammals in the diet of the barn owl Tyto alba and the tawny owl Strix aluco in localities in north-western Poland

Abstract:

Analysis of food composition of two owl species (Tyto alba and Strix aluco) in 14 study sites in the years 1998–2024 revealed the presence of 22 species of small mammals. Five species of Soricomorpha (Talpa europaea, Sorex araneus, S. minutus, Neomys fodiens and Crocidura suaveolens), four species of Chiroptera (Myotis myotis, M. nattereri, Eptesicus serotinus and Nyctalus noctula), 12 species of Rodentia (Clethrionomys glareolus, Arvicola amphibius, Microtus arvalis, M. subterraneus, M. agrestis, M. oeconomus, Mus musculus, Rattus norvegicus, Apodemus agrarius, A. sylvaticus, A. flavicollis and Micromys minutus) and one species (Mustela nivalis) of the order Carnivora were found. Three species: S. araneus, M. arvalis and M. musculus clearly dominated in the diet of the T. alba. Forest rodents: C. glareolus, A. flavicollis and in one site M. arvalis were most common in the diet of S. aluco. Noteworthy is the great share of M. agrestis in the diet of S. aluco, which is rarely noted in other regions of the country. Distinctly increased share of Chiroptera (3 species) constituting 10.1% of prey items of T. alba was recorded in one site in Przelewice.
