Fig. 6. Limb positions vs time for separate representative glide sequences. Limb movements were ubiquitous throughout all glides and of magnitudes that far exceed the estimated digitizing error. The correlation between these movements and body rotations indicate that these movements function to control body orientation. (A) Chord angles tended to be fairly large and positive at the start of the sequences and decrease through the trial. Chord angles became negative in 14 of 49 trials. (B) Forelimb elevation angles tended to fluctuate between positive and negative, but usually remained fairly small. (C) Forelimb protraction angles were large and positive at all times in all glide sequences.
