高速摄影技术被用来分析鸽子啄小视觉目标的头部运动序列，并确定目标落在视网膜上的不同位置。在为食物奖励和正常进食的关键啄食中，啄目标的决定是在头部注视发生在距离目标所在表面超过80 mm(从眼睛中心测量)的过程中做出的。一旦决定啄食，第二次固定(F2)发生在平均55毫米的距离，允许鸟计算目标的大小、深度和位置。在两次注视中，靶点都位于鸽子S的双目视野内，该区域对应于视网膜颞叶上象限的红色区域。
High-speed cinematography was used to analyze the sequence of head movements made by pigeons pecking at small visual targets and to determine where on the retina the target fell at different points in the sequence. In both key-pecking for food reward and normal feeding, the decision to peck the target was made during a head fixation that occurred over 80 mm from the surface on which the target was located (as measured from the center of the eyes). Once the decision to peck had been made, a 2nd fixation (F2) occurred at an average distance of 55 mm allowing the bird to calculate the size, depth, and location of the target. During both fixations, the target was located in the pigeon''s binocular field within a region corresponding to the red area of the upper temporal quadrant of the retina.
