In the struggle for survival, scatter‐hoarding rodents are known to cache food and pilfer the caches of others. The extent to which rodents utilize auditory/visual cues from conspecifics to improve cache‐pilfering is unknown. Here, Siberian chipmunks (Tamias sibiricus) were allowed to search for caches of Corylus heterophylla seeds (man‐made caches and animal‐made caches) after experiencing cues from a conspecific's cache‐searching events. For each type of cache, 3 experimental scenarios were presented: (1) alone (control); (2) auditory/visual (hearing and seeing conspecific's cache‐searching events); and (3) auditory only (hearing conspecific's cache‐searching events only) with random orders. The subjects located man‐made caches faster, harvested more caches, and hoarded more seeds both in the auditory/visual and the auditory only treatments compared to the control, while scatter‐hoarding more seeds in the auditory/visual treatment but larder‐hoarding more seeds in the auditory only treatment. Compared to the control, the animals spent less time locating animal‐made caches, harvested more caches, ate fewer seeds, larder‐hoarded more seeds and hoarded more seeds in total both in the auditory/visual and the auditory only treatments, while eating more seeds and hoarded fewer seeds in total in the auditory only treatment than in the auditory/visual treatment. The results also show that females spent less time locating the animal‐made caches, but they scatter‐hoarded fewer seeds than males in the auditory/visual treatment. To the best of our knowledge, this is the first report that visual and/or auditory cues of conspecifics improve cache‐pilfering and hoarding in rodents.

视觉和听觉提示有助于在室内条件下对西伯利亚花栗鼠（Tamias sibiricus）进行缓存盗窃。

在为生存而奋斗的过程中，众所周知，散布啮齿类的啮齿动物会储存食物并偷窃他人的藏匿处。啮齿动物在多大程度上利用特定物种的听觉/视觉提示来改善缓存窃取的程度尚不清楚。在这里，花鼠（Tamias芒）被允许搜索的高速缓存榛子在经历了同种的缓存搜索事件提示后的种子（人造缓存和动物缓存）。对于每种类型的缓存，提出了3种实验方案：（1）单独（控制）；（2）听觉/视觉（听到和看到同种的缓存搜索事件）；（3）仅听觉（仅听取特定类的缓存搜索事件）且顺序随机。与对照相比，受试者在听觉/视觉和仅听觉处理中更快地找到了人造缓存，收获了更多的缓存，并且ho积了更多的种子，而在听觉/视觉处理中散布了更多的种子，但是but积了更多种子在听觉上只能治疗。与对照组相比，动物花费更少的时间查找动物制成的藏匿处，收获更多藏匿处，少吃种子，在听觉/视觉和仅听觉处理中，贮藏量更多，种子的总贮藏量更多；而在听觉/视觉处理中，进食较多的种子和种子的总贮藏量少于听觉/视觉处理。结果还表明，在听觉/视觉处理中，雌性花在寻找动物制成的藏身处的时间更少，但散布在种子中的种子比雄性少。据我们所知，这是第一份关于特定物种的视觉和/或听觉线索可以改善啮齿动物的缓存偷窃和ho积的报告。但是在听觉/视觉处理中，它们散布的种子比男性少。据我们所知，这是第一份关于特定物种的视觉和/或听觉线索可以改善啮齿动物的缓存偷窃和ho积的报告。但是在听觉/视觉处理中，它们散布的种子比男性少。据我们所知，这是第一份关于特定物种的视觉和/或听觉线索可以改善啮齿动物的缓存偷窃和ho积的报告。
