Predicted probability to discover box pairs by visiting suitable roosts depending on the cumulative number of visits to unsuitable (a) and suitable boxes (b) by female Bechstein’s bats (n = 34). The estimate and its 95% confidence interval were based on our best fitted generalized additive mixed model (GAMM) including the cumulative number of suitable and unsuitable visits as fixed effects; bat identity and colony were random intercepts. While investigating the effect of each factor separately the remaining factor was set to its mean. Given the similar behavior of the two colonies, we present only the estimated probabilities for the Blutsee colony as a representative
