Avian Bipedal Locomotion: XROMM animation
Hind limb movement during steady walking in Numida meleagris
XROMM animation of the pelvis and right hind limb bones of a Helmeted Guineafowl walking steadily at 0.6 m/s. The femur, tibiotarsus, and tarsometatarsus undergo subtle long-axis rotations as the limb moves through 3-D space. The playback speed is one tenth of the real speed. Animated by S.M. Gatesy, R.E. Kambic, and T.J. Roberts.
