Abstract

The study was conducted with pellets of the long–eared owls (Asio otus) from two periods (January 2006 and January 2007) in suburban area of Prelog (northern Croatia). A total of 113 pellets with 198 prey items were analysed. The averaged number of prey individuals per pellet was 1.75 (SD = 0.99). Twelve small mammalian species (97.9% in number and 97.1% in biomass) and three bird species (2.1% in number and 2.9% in biomass) were preyed upon. By comparing the number of prey items between 2006 and 2007 no significant differences were found.
