Fig. 11. We observed a number of asymmetries in the wing kinematics of the cockatoos
as they navigated the maneuvering course, including but not limited to the
following. (A) Asymmetric wrist flexion angles at the start of downstroke, (B)
asymmetric wrist angles and wingtip trajectories at the end of downstroke, and
(C) asymmetric wing velocity vectors angles at the start of downstroke. These
asymmetries all occur in the 3D reconstruction as well as the 2D projections
given by the camera, although the camera views do accentuate some asymmetries.
However, none of these asymmetries was significantly correlated with changes
in heading or roll.
