Does a live barn owl (Tyto alba) affect emergence behavior of serotine bats (Eptesicus serotinus)?

Popis výsledku v původním jazyce

We studied the impact of predation risk on emergence behavior of a maternity colony of Eptesicus serotinus. Observations were made during sets of three consecutive nights ů control, treatment and post-treatment. On treatment nights, a trained individualof barn owl (Tyto alba) was displayed during the emergence of the colony. Presence of the owl did not induce any significant change in the emergence parameters with exception of the degree of clustering. In pregnancy bats increased their clustering during treatment and post-treatment nights. The presence of the owl induced changes in relationships among emergence parameters. If bats emerged earlier when predation risk supposed to be higher, they increased their degree of clustering to decrease the individuals probability of being attacked. We conclude that clustering in emergence is an important anti-predation strategy.
