Abstract:
The species composition of a small mammal community in the diet of the Barn Owl Tyto alba was examined at two sites near the town of Świecie nad Wisłą (northern Poland). Bones of 161 prey were extracted from T. alba pellets collected in 2021 and 2023. A total of 14 mammalian species were recorded: Soricomorpha (3) and Rodentia (11). The dominant species in the diet of T. alba at both sites was Microtus arvalis, accounting for 24–48%. The second most common species in the diet of owls was Sorex araneus. A significant difference between the sites is the ratio of Microtidae to Muridae in the food of the Barn Owl. The most interesting species was Crocidura suaveolens, whose localities are located outside the previously known north-eastern limit of its range. Possible pathways for the spread of this species beyond its current geographic range are discussed.
