From: Syringeal vocal folds do not have a voice in zebra finch vocal development
Minimal frequency does not change over zebra finch song development. (a) Mean and S.D. (inset) fundamental frequency in the pb − picas pressure control space for the left and right hemi-syrinx in males over vocal development. (b) Minimum fo does not change with age in males and females. (c) Minimum frequency was significantly different between the left and right hemi-syrinx, regardless of age or sex. (d) Slope S1 for the relationship between fo and pt was not significantly different for side. (e) Fundamental frequency in the pb − picas pressure control spaces for the left and right hemi-syrinx in females. For statistics see Supplementary Table S2. ***p < 0.001.
