Table 1 Output from LMMs or GLMMs testing the effects of prenatal playback of incubation calls (treatment; n = 13) or contact calls (control; n = 18) on the number of song syllables that males (a) copied from their father, (b) failed to copy from their father, and (c) copied from non-father males or improvised. Models include playback treatment, father song complexity (number of different syllable types), and son nestling mass as fixed effects; and father identity as a random effect. For the variable ‘playback treatment’, estimates and SEs are for treatment males, with control as a reference.
