In PNAS, Fayet et al. (1) report on two cases of tool use in a seabird. In two distant populations they recorded Arctic puffins (Fratercula arctica) using sticks to scratch themselves (Fig. 1). The documentation of tool use in this species expands the ever-growing list of tool-using birds through rare observations under natural conditions. Although it is neither the first observation of tool use in wild seabirds, nor the first of stick-tool use outside of a foraging context in wild birds, these findings contribute to the debate on the evolutionary and cognitive origins of tool use.

使用工具的海雀刺痛了认知进化的难题。

在 PNAS 中,Fayet 等人。( 1 ) 报告两起在海鸟身上使用工具的案例。在两个遥远的种群中,他们记录了北极海雀(Fratercula arctica)用棍子抓自己(图1)。通过在自然条件下的罕见观察,该物种使用工具的记录扩大了不断增长的使用工具鸟类的名单。虽然这既不是第一次观察到野生海鸟使用工具,也不是第一次在野生鸟类觅食环境之外使用棒状工具,但这些发现有助于关于工具使用的进化和认知起源的辩论。
