许多动物依靠视觉在它们的环境中成功地移动。然而，令人惊讶的是，我们对视觉和运动之间相互作用的理解是有限的。因此，这项研究考察了引导鸟类跳跃运动的视觉机制。它记录了圈养的印度孔雀(Pavo Criatus)在栖息地上下跳跃时的眼球运动。孔雀在跳跃时眼睛向前移动，增加了双眼重叠的程度。他们的眼球运动在跳跃时是高度共轭的，但在其他方面是松散的共轭。最后，孔雀很少把目光对准着陆点。这些结果表明，眼球运动在鸟类的运动中起着核心作用，它们可以根据具体的运动任务而变化。摘要：在跳跃运动中，雌性孔雀很少盯着它们的着陆点，它们的眼球运动在向前移动时高度共轭，这表明视觉在运动中起着关键作用，这取决于运动任务。
ABSTRACT Many animals rely on vision to successfully locomote through their environments. However, our understanding of the interaction between vision and locomotion is surprisingly limited. This study therefore examined the visual mechanisms guiding jumping locomotion in an avian species. It recorded the eye movements of captive Indian peafowl (Pavo cristatus) as they jumped up onto and down from a perch. Peafowl shifted their eyes forward as they were jumping, increasing the degree of binocular overlap. Their eye movements were highly conjugate as they were jumping but were otherwise loosely conjugate. Finally, the peafowl rarely directed their gaze toward landing spots. These results suggest that eye movements play a central role in avian locomotion and they can vary depending on the specific locomotor task. Summary: During jumping locomotion, female peafowl rarely gaze at their landing spots and their eye movements are highly conjugate while shifting forward, suggesting that vision plays a critical role in locomotion that varies depending on the locomotor task.
