Abstract

Cognition is a powerful adaptation, enabling animals to utilise resources that are unavailable without manipulation. Tool use and food processing are examples of using cognition to overcome the protective mechanisms of food resources. Here, we describe and examine the flexibility of proto-tool use (defined as the alteration of an object through object-substrate manipulation) for food processing in a cooperatively breeding bird, the Arabian babbler (Argya squamiceps). Field observations demonstrate that the birds transport different caterpillar species to different substrate types depending on the processing method needed to prepare the caterpillar for eating. Species with toxic setae (e.g. Casama innotata) are transported to be rubbed on rough substrates (e.g. sand) before consumption, while other species (e.g. Hyles livornica) are transported to be pounded against hard substrates until their inner organs are removed and only their external body part is consumed. These results are among the few to describe flexible proto-tool use for food processing in wild animals. They thereby contribute to the taxonomic mapping of proto-tool use and food processing in non-human species, which is a fundamental step to advance comparative studies on the evolution of these behaviours and their underlying cognitive mechanisms.

野生阿拉伯狒狒使用原工具加工食物:加工方法、基质和猎物类型的匹配
认知是一种强大的适应能力,它使动物能够利用不加操作就无法获得的资源。工具使用和食物加工就是利用认知克服食物资源保护机制的例子。在这里,我们描述并研究了一种合作繁殖的鸟类--阿拉伯狒狒(Argya squamiceps)--使用原工具(定义为通过物体-基质操作改变物体)处理食物的灵活性。实地观察表明,鸟类会将不同种类的毛虫搬运到不同的基质上,这取决于毛虫食用前所需的处理方法。带有毒性刚毛的毛虫(如 Casama innotata)会被运到粗糙的基质(如沙)上摩擦后再食用,而其他种类的毛虫(如 Hyles livornica)则会被运到坚硬的基质上敲打,直到去除内脏,只食用外部身体部分。这些结果是为数不多的描述野生动物利用灵活的原生工具加工食物的结果。因此,它们有助于在分类学上绘制非人类物种使用原型工具和加工食物的图谱,这对于推进这些行为及其潜在认知机制的进化比较研究来说是至关重要的一步。

期刊介绍: Animal Cognition is an interdisciplinary journal offering current research from many disciplines (ethology, behavioral ecology, animal behavior and learning, cognitive sciences, comparative psychology and evolutionary psychology) on all aspects of animal (and human) cognition in an evolutionary framework. Animal Cognition publishes original empirical and theoretical work, reviews, methods papers, short communications and correspondence on the mechanisms and evolution of biologically rooted cognitive-intellectual structures. The journal explores animal time perception and use; causality detection; innate reaction patterns and innate bases of learning; numerical competence and frequency expectancies; symbol use; communication; problem solving, animal thinking and use of tools, and the modularity of the mind.
