Specializations in the lumbosacral vertebral canal and spinal cord of birds: evidence of a function as a sense organ which is involved in the control of walking
R Necker - Journal of Comparative Physiology A, 2006 - Springer
Birds are bipedal animals with a center of gravity rostral to the insertion of the hindlimbs.
This imposes special demands on keeping balance when moving on the ground. Recently …

A physical model suggests that hip-localized balance sense in birds improves state estimation in perching: implications for bipedal robots
In addition to a vestibular system, birds uniquely have a balance-sensing organ within the
pelvis, called the lumbosacral organ (LSO). The LSO is well developed in terrestrial birds …

Consequences of lost endings: caudal autotomy as a lens for focusing attention on tail function during locomotion
Autotomy has evolved in many animal lineages as a means of predator escape, and
involves the voluntary shedding of body parts. In vertebrates, caudal autotomy (or tail …
