Prey selection and seasonal diet changes in the western barbastelle bat (Barbastella barbastellus)

Original language description

The objective of the study was to describe the diet composition of western barbastelle bat (Barbastella barbastellus), its seasonal changes and main factors determining trophic niche of the species. Barbastelle bat feeds predominantly on moths and has the narrowest trophic niche within the entire studied bat community. A comparison of the food supply and the diet composition showed selectivity for larger species of moths. An increasing of absolute abundance of preferred larger moths within summer is accompanied with narrowing of bat's trophic niche. This pattern corresponds well with the conclusions of optimal foraging theory. Larger moths are preferred even in a period of their low relative abundance within a peak of abundance of smaller species. There are no abrupt seasonal changes in the bat's diet within season, but the narrow pool of available food supply seems to determine the trophic niche breadth within low prey diversity periods in early spring and late autumn.
