Food caching by the red fox, Vulpes vulpes, may safeguard surplus food for future consumption. Because of practical difficulties involved in observation the extent to which the fox making a cache, or any other fox, can utilise the hoard was not known. This problem is tackled through extended observation, using unfra-red binoculars, on wild foxes (some of which were radio-tagged), together with experiments involving hand-reared tame foxes, either walked on a long leash or free and radio-tagged. The results demonstrate the fox's ability to rediscover its caches and shed light on the adaptive significance of the behaviour, which is then dsicussed in the context of food safeguarding by other carnivores.
赤狐（Vulpes vulpes）贮藏食物可能是为了储备多余的食物以供日后食用。由于观察存在实际困难，所以不清楚藏食的狐狸或其他狐狸能在多大程度上利用贮藏的食物。通过使用红外双筒望远镜对野生狐狸（其中一些带有无线电标签）进行长期观察，并结合对人工饲养的 tame 狐狸进行的实验来解决这个问题，这些 tame 狐狸要么用长绳牵着行走，要么自由活动并带有无线电标签。结果证明了狐狸重新找到其贮藏食物的能力，并揭示了这种行为的适应性意义，随后将在其他食肉动物贮藏食物的背景下对此进行讨论。
原文中“tame”可能有误，推测应为“tamed”。
