摘要在基于视图的导航中，动物从不同的位置获取景观的视图，然后将学习到的视图与当前视图进行比较，以便在某些方向上定向或向某些目的地移动。在基于视图的导航中具有巨大潜在用途的一个景观特征是天际线，即地面物体在天空中的轮廓，因为它距离较远，相对稳定且易于检测。天际线在蚂蚁基于视觉的导航中已经被证明是重要的，但是还没有明确的飞行昆虫以这种方式使用天际线。在这里，我们表明蜜蜂确实使用天际线定向。一个喂食器周围环绕着一个人造的自然天际线的复制品，蜜蜂离开巢穴的过程是在阴天下用摄像机从上面记录下来的（以消除天体的暗示）。当人造天际线旋转时，蜜蜂的出发点也相应旋转，这表明蜜蜂仅由人造天际线定向。我们讨论了这些发现的背景下，可能的重要性的天际线在蜜蜂的远程归巢，海拔高度可能的重要性，在使用的天际线，紫外线的可能作用，在检测天际线，以及我们所知道的蜜蜂的能力，解决天际线的功能。总结：蜜蜂可以利用天际线来确定方向，天际线是地面物体在天空中的全景轮廓，这种能力对蜜蜂的日常导航很重要。
ABSTRACT In view-based navigation, animals acquire views of the landscape from various locations and then compare the learned views with current views in order to orient in certain directions or move toward certain destinations. One landscape feature of great potential usefulness in view-based navigation is the skyline, the silhouette of terrestrial objects against the sky, as it is distant, relatively stable and easy to detect. The skyline has been shown to be important in the view-based navigation of ants, but no flying insect has yet been shown definitively to use the skyline in this way. Here, we show that honeybees do indeed orient using the skyline. A feeder was surrounded with an artificial replica of the natural skyline there, and the bees' departures toward the nest were recorded from above with a video camera under overcast skies (to eliminate celestial cues). When the artificial skyline was rotated, the bees' departures were rotated correspondingly, showing that the bees oriented by the artificial skyline alone. We discuss these findings in the context of the likely importance of the skyline in long-range homing in bees, the likely importance of altitude in using the skyline, the likely role of ultraviolet light in detecting the skyline, and what we know about the bees' ability to resolve skyline features. Summary: Honeybees can orient using the skyline, the panoramic silhouette of terrestrial objects against the sky, an ability probably important to bees in their everyday navigation.
