物体或环境地标的识别是有问题的，因为外观可以根据照明、观看距离、视角等而广泛变化（1）。为每一个可能的视图存储一个单独的图像或“模板”需要存储和扫描大量的图像，识别错误的可能性很高，似乎不是灵长类动物采用的解决方案（2-3）。然而，一些无脊椎动物模板匹配系统可以通过“主动视觉”来实现识别，其中动物自身的行为被用于实现模板和对象（4）之间的匹配，例如通过重复地遵循设定的路径（5-7）。因此，识别仅限于来自设定路径的视图，但用最少数量的模板来实现。在这里，我们报告的第一个证据，类似的主动视觉在一只鸟，在运动的形式和单独不同的头部运动，使眼睛在不同的场合类似的一系列意见。母鸡识别物体的能力也被发现在它们的正常路径被改变时下降。
Recognition of objects or environmental landmarks is problematic because appearance can vary widely depending on illumination, viewing distance, angle of view and so on(1). Storing a separate image or 'template' for every possible view requires vast numbers to be stored and scanned, has a high probability of recognition error and appears not to be the solution adopted by primates(2-3). However, some invertebrate template matching systems can achieve recognition by 'active vision' in which the animal's own behaviour is used to achieve a fit between template and object(4), for example by repeatedly following a set path(5-7). Recognition is thus limited to views from the set path but achieved with a minimal number of templates. Here we report the first evidence of similar active vision in a bird, in the form of locomotion and individually distinct head movements that give the eyes a similar series of views on different occasions. The hens' ability to recognize objects is also found to decrease when their normal paths are altered.
