There is an error in the fifth row values for Table 1. Please see the correct Table 1 here.

Additionally, there is an error in the values for the parameter syllables/second for Fig. 5b. Please view the correct Fig. 5 here.

Box plots are separated by sex and population. Abbreviations and colours as in Figure 4. Asterisks denote the cases where found differences were significant (p≤0.05 (*), p≤0.01 (**)).

Finally, there is an error in the last two sentences of the last paragraph of the “Temporal Analysis” sub-section under the “Results” section. Please refer to the correct paragraph here.

To find the factors responsible for these differences, we conducted post-hoc tests (Wilcoxon rank-sum test) for the DiffSex and the SameSex situations and corrected for multiple testing (Bonferroni, DiffSex: p’ = p * 4, SameSex: p’ = p * 2). In the SameSex situation females emitted longer songs than males (W = 245, p’ = 0.0085). In the DiffSex situation French mice emitted more syllables per second than German mice (W = 27820, p’ < 0. 0001). In both situations, males emitted more syllables per second than females of the same population (DiffSex: W = 27029, p’ < 0.0001; SameSex: W = 14304, p’ < 0.0001).
