在鸽子掌握的定量分析表明，重要的功能相似性之间的视觉控制的鸟类喙和灵长类动物的手。在进食过程中，嘴的张开（张口）与目标的大小成正比，并且在接触之前完成调整。张口的大小的控制涉及的变化，在速度和持续时间的下巴打开，这些参数是由不同的效应器系统（下巴肌肉，颈部肌肉）介导。神经切片实验被用来确定颌骨运动神经元，这是最终的共同路径的组成部分，为抓。鸽子的抓握近似于哺乳动物视觉行为的功能复杂性，但由相对简单的效应器系统介导。
A quantitative analysis of grasping in the pigeon suggests important functional similarities between the visuomotor controls of the avian beak and the primate hand. Beak-opening (gape) during eating is directly proportional to target size and the adjustment is completed prior to contact. The control of gape size involves variations in both the velocity and duration of jaw opening and these parameters are mediated by different effector systems (jaw muscles, neck muscles). Nerve section experiments were used to identify jaw motoneurons which are components of the final common path for grasping. Grasping in the pigeon approximates the functional complexity of mammalian visuomotor behavior but is mediated by a relatively simple effector system.
