鸽子、鸡和许多其他常见的鸟类在走路时会前后摆动脑袋，这给人的印象很有说服力，但却很虚幻。事实上，行走的鸟会将头向前推进，然后保持几乎静止，同时颈部收缩，身体跟上。头部相对于身体前后移动，但在环境中只向前移动。虽然这在40多年前的电影中已经得到了证明，但关注视觉系统进化的理论家们2 - 4仍然认为头部的来回摆动对鸟类的视觉很重要。
THE impression that pigeons, chickens, and many other common birds bob their heads backward and forward as they walk is compelling but illusory. In reality, the walking bird thrusts its head forward, then holds it nearly stationary while the neck retracts and the body catches up. The head moves backward and forward with respect to the body, but moves only forward in the environment. Although this was demonstrated on film more than 40 years ago1, theorists concerned with the evolution of visual systems2–4continue to suggest that a back and forth oscillation of the head is important in avian vision.
