摘要
The prey selection of short-eared owl (Asio fiammeus) was studied based on pellet analysis. The owls consumed primarily mammals (99.4%), with the most important prey species being Microtus arvalis (94.7%) followed by Mus spicilegus, Crocidura suaveolens and Melanocorypha calandra. The selected prey species are common food components of this species; the food niche breadth was similar to the one in most studies in Central and Southern Europe and highlights the high food specialisation of short-eared owls.
