Figure 6. Female removal changed syllable parameters.

A) For all syllables combined, the dominant frequency increased after removal of the female, as did the dominant frequency of “complex,” “down,” and “short” syllables. B) Both “complex” and “short” syllables decreased in duration after females were removed. C) Bandwidth increased for “flat” and “short” syllables between sub-contexts. With Wilcoxon signed ranks tests, all comparisons were significant after FDR corrections at the *p<0.05 level.
