扩展的地面结构，如道路或田地边缘，可以是动物导航的重要线索，例如在道路跟踪鸽子中看到的。在一个没有天际线线索，但有一个矩形网格的路径和道路的景观，我们使用谐波雷达跟踪自由飞行的熊蜂，熊蜂terrestris。个别蜜蜂一贯使用地面线性功能导航在广泛的人工智能的背景。蜜蜂探索飞行，搜索行为和觅食路线的形状由线性特征，蜜蜂经常飞行沿着和平行的路径和道路。在这些行为背景下的飞行轨迹的比较表明，个人调制他们的线性features的使用策略，就其个人的目标和经验。寻找喂食器的蜜蜂使用线性特征来定位它们的搜索，而觅食者通常沿着路径返回蜂巢而不会过度。这些关于主要传粉者的发现对农业蜂群的位置和保护花卉资源具有重要意义。(c)2021年，任作家。由Elsevier Ltd代表动物行为研究协会出版。这是CC BY许可证下的开放获取文章（http：creativecommons.org/licenses/ by/4.0/）。
Extended ground level structures like roads or field edges can be important cues for navigating animals, seen for example in road-following pigeons. In a landscape devoid of skyline cues but with a rectangular grid of pathways and roads, we used harmonic radar to track free-flying bumble bees, Bombus terrestris. Individual bees consistently used ground level linear features for navigation in a wide range of behav-ioural contexts. Bee exploration flights, search behaviour and foraging routes were shaped by linear features, with bees frequently flying along and parallel to pathways and roads. Comparisons of flight trajectories across these behavioural contexts show that individuals modulated their use of linear fea-tures strategically with respect to their individual goals and experience. Bees searching for a feeder used linear features to target their search, while foragers often followed pathways to return to their hive without overshooting. These findings on a major pollinator have important implications for the place -ments of bee colonies for agriculture and floral resources for conservation. (c) 2021 The Authors.
