From: Syringeal vocal folds do not have a voice in zebra finch vocal development
Wiener entropy and mechanical efficiency do not change over zebra finch song development. (a) In males, Wiener entropy (WE) for the left and right hemi-syrinx in males age 25 and 100 DPH. (b) WE did not change for males over development. (c) Mechanical efficiency (ME) for the left and right hemi-syrinx in males age 25 and 100 DPH. (d) The mean ME produced for males significantly differed over development. (e) In females, WE did not significantly change over development. (f) WE did not change for females over development. (g) Mechanical efficiency (ME) for the left and right hemi-syrinx in females age 25 and 100 DPH. (h) The mean ME of female syrinxes decreased significantly over development. For statistics see Supplementary Table S2. *p < 0.05.
