鸟类的腰骶椎和脊髓在解剖学上有特殊性。这些包括与脊髓副叶相关的分段组织的骨管。两个结构通过脑脊液连接。为了测试这些特化是否起到平衡感觉器官的作用，在鸽子身上研究了打开液体空间的效果。损伤后，地面运动行为（落在栖息处、在旋转栖息处保持平衡、行走）在栖息处、在旋转栖息处保持平衡、行走）但飞行行为没有显着受损。这些结果支持腰骶骨特化参与地面运动控制的假设。
In birds there are anatomical specializations in the lumbosacral vertebrae and spinal cord. These include segmentally organized bony canals which are related to accessory lobes of the spinal cord. Both structures are connected by cerebrospinal fluid. To test whether these specializations function as a sense organ of equilibrium the effect of opening the fluid space was studied in pigeons. Locomotory behaviors on the ground (landing on a perch, keeping balance on a rotating perch, walking) on a perch, keeping balance on a rotating perch, walking) but not flight were significantly impaired after lesion. These results support the assumption that the lumbosacral specializations are involved in the control of locomotion on the ground.
