Table 3 Output from GLMMs testing the effects of song learning on the likelihood of male mounting during a mating trial, independent of prenatal playback treatment. Each model used mounting (yes/no, per trial) as the dependent variable, and one measure of song copying accuracy (n = 148 trials from 31 males) or song complexity (n = 188 trials from 39 males) as the fixed effect. Female movement (normal/abnormal) was also included as a fixed effect, with male identity and female identity included as random effects unless their parameter estimate was nil.
