摘要: The aim of this work was to investigate the diet Tawny Owl (Strix aluco) in NE Poland. Pellets were collected territory one owl centre Romincka Forest twice a year, spring and autumn, from 2000 2003. Among 450 identified prey items, rodents (38% items), amphibians (34%) insectivores (17%) constituted dominant groups. Birds caught only occasionally (5%). Significant differences found composition between two seasons. hunted more frequently winter spring, whereas proportion murid higher summer-autumn period. percentages microtines pellets comparable Amphibians preyed on had thicker femurs than those summer autumn.
