Fig. 3. The relationship between zebra finch pectoralis function and flight speed.
(A) EMG duty cycle. (B) Relative EMG intensity. (C) Fascicle strain. (D)
Wingbeat frequency. (E) Proportional shortening duration. The numbers adjacent
to the data points denote homogenous subsets between which no significant
differences were detected using a Scheffé post-hoc test
(P>0.05). Values are means ± s.e.m. (N=6).
