Abstract

In the years 2007-2016 the food composition of Tawny Owls Strix aluco was examined in „Dębina I” reserve in Masovian Voivodship (52.40°N, 21.38°E). In the analysed bone material 2,655 vertebrate prey items were found, among which there were 1,513 individuals of mammals. On that basis, it was established that the area and the nearest surrounding were inhabited by at least 21 species of small mammals. The following species were recorded: three soricomorphs Soricomorpha, eight bats Chiroptera, nine rodents Rodentia and one of the order Carnivora. All of them belong to species whose ranges cover the whole Masovia. Substantial forest fragmentation and the lack of connection with larger forests could be responsible for the absence of some rodent species which ranges cover this part of the country. It is worth emphasizing the presence of relatively rich assemblage of bats, among which Lesser Noctule Nyctalus leisleri and Brandt’s Bat Myotis brandtii are valuable and rarely noted species. The most often species preyed by owls were the following: among bats – Brown Long-eared Bat Plecotus auritus (20 out of 35 individuals, 1.3% of mammalian prey), soricomorphs – Common Shrew Sorex araneus (5.6%), rodents – Yellow-necked Mouse Apodemus flavicollis (29,0%) and Bank Vole Myodes glareolus (23,5%).
