FLEDGLING PRODUCTIVITY IN RELATION TO DIET COMPOSITION OF TENGMALM'S OWL AEGOLIUS FUNEREUS IN CENTRAL EUROPE

Popis výsledku v původním jazyce

Based on 52 nesting attempts of Tengmalm's owl Aegolius funereus in the Sumava Mountains (South Bohemia, Czech Republic), in habitats comprised mainly of Norway spruce forests, we investigated the relationships between diet composition and fledgling productivity of this owl. We found that (i) owls feed mainly on Sorex shrews (39%), Microtus voles (19%), Apodemus mice (15%), bank voles Myodes glareolus (14%) and birds (6%), (ii) the percentage of Apodemus mice, as well as the percentage of Myodes glareolus, negatively correlated to the percentage of Sorex shrews and birds in the owls' diet, and (iii) the fledgling productivity of the owls positively correlated to the percentage of Apodemus mice in the diet. Finally, (iv) the percentage of Microtus voles, the second most common prey, exhibited no close relationships with other prey groups or fledgling productivity of the owls. These results suggest that Apodemus mice were an important prey in the diet of the Tengmalm's owl in our study a
