在 4 只鸽子 (Columba livia) 的运动和啄食行为过程中，同时记录了头部和眼睛的运动，这些鸽子经过训练，穿过调节室，两端各有一个啄键和一个食物分配器。每次试验都涉及啄键、行走和喂食。用头骨上安装的微型加速度计记录头部运动，用植入的眼电电极记录眼球运动。在行走和进食过程中，观察到头部和眼睛运动之间几乎完美的时间协调。行走过程中，头部运动主要提供视网膜图像稳定性，眼球运动支持视觉扫描。在喂食过程中，头部运动主要有助于抓握食物，而眼球运动则维持对食物的视觉固定。因为在啄食的中间阶段眼睛会反射性地闭上，所以头部和眼睛的运动受到弹道控制。
Head and eye movements were simultaneously recorded during locomotory and pecking behavior of 4 pigeons (Columba livia), which were trained to traverse a conditioning chamber, with a pecking key and a food dispenser at each end. Each trial involved key pecking, walking, and feeding. Head movements were registered with a skull-mounted miniature accelerometer, and eye movements were recorded with implanted electrooculographic electrodes. An almost perfect temporal coordination between head and eye movements was observed during both walking and feeding bouts. During walking, head movements primarily provide retinal image stability, and eye movements support visual scanning. During feeding, head movements mainly subserve the grasping of food items, and eye movements maintain visual fixation on them. Because the eyes are reflexively closed during the middle phase of pecks, the head and eye movements are then under ballistic control.
