  1. Results of generalized linear mixed model with estimates, standard deviation, and credible intervals using WinBUGS for (a) playback and (b) decoy experiment. Stimulus is defined as random factor to compare paths of all stimuli and thus correct for multiple testing. A behavioural response differs significantly from the local population if its credible intervals do not include the mean of the local population. Significant results are shown in bold.
