The role of Apodemus mice and Microtus voles in the diet of the Tengmalm's owl in Central Europe

Popis výsledku v původním jazyce

Based on a long-term dataset (1999-2010), we investigated how the availability of main prey affects the breeding density and food ecology of the Tengmalm's owl (Aegolius funereus) in the Czech Republic. In particular, we assessed the role of Microtus voles and Apodemus mice in the diet, based on the main predictions of the optimal diet theory that the diet composition depends on the availability of the main prey. We found that (i) the Tengmalm's owl exhibited no numerical response to the availability ofMicrotus voles and Apodemus mice in the field; (ii) the availability of Apodemus mice in the field positively affected their proportion in the diet (26 %), and despite a high proportion of Microtus voles in the owls' diet (47 %), no relationship was found between their availability in the field and proportion in the diet; (iii) the proportion of Apodemus mice was negatively correlated to the proportion of Microtus voles, Sorex shrews and birds in the diet, but no similar relationship wa
