Table 2.
Duration of delay to resume feeding after initiation of playback. Results from a linear mixed model comparing the ranked duration of delay time. T ratios > 0 indicate that the first-named treatment has a higher rank, and thus a longer delay, than the second-named treatment. Post hoc comparison p-values were Tukey adjusted. Bolded p-values indicate statistical significance.
