Figure 7

Correlation of mean vocalization energy with mean vocalization entropy variance and mean vocalization energy with the mean total song count in males and females during week 1 and week 3. Closed circles represent male mean values and open circles represent female mean values. Trend lines for males are solid lines and dashed lines for females. Significant trend lines are highlighted in grey. A) For males during week 1 there is a significant linear relationship between the loudness of a vocalization and its acoustic stability with louder vocalizations being having higher entropy variance, which is, associated with less stability (i.e. less stereotyped vocalizations). B) Furthermore, there was a striking sex and week interaction where for males only during week 3 we observed that the greater the vocalization energy the greater the mean total number of bouts per recording.
