圈养出生的雄性和雌性松鼠猴自发地“发明”了一种杯子工具使用技术来容纳（即，他们把食物切成碎片食用，并把从阀门收集来的水喝。观察到使用食物杯比使用水杯更频繁。观察结果表明，该种群中68%（n= 39/57）的猴子使用杯子（塑料滑帽）来盛装食物，其中10%（n= 4/39）的猴子也使用杯子来盛装水。杯子的使用是可选的，并没有取代，但补充，手/臂对嘴进食和直接阀饮水的所有成员的人口。猴子在喜欢的上层栖息地，在它们生活的类似树木的环境中，将食物和杯子放在一起进行食物加工活动的策略提供了证据，表明猴子可能计划用杯子进行食物加工活动。具体而言，在使用杯子之前，猴在食物之前首先获得杯子，或者在将食物和杯子运送到上层栖息区域之前同时从地板上获得食物和杯子。在用杯子进行食物加工活动后，猴子很少会把杯子掉在地上，更经常的是把杯子放在栖木上。猴子随后返回使用先前在食物加工活动后放置在栖木上的杯子。后者的行为是一致的可能性，猴子可能会保持杯子在首选栖息地为未来的食品加工活动，值得实验研究。关于松鼠猴自发使用工具的报告很少，这是第一份关于群体水平工具使用的报告。这些发现为松鼠猴的认知能力提供了新的见解，并为该属的行为研究以及与其他灵长类动物的比较研究提供了新的背景。Am.

Captive‐born male and female squirrel monkeys spontaneously ‘invented’ a cup tool use technique toContain(i.e., hold and control) food they reduced into fragments for consumption and toContainwater collected from a valve to drink. Food cup use was observed more frequently than water cup use. Observations indicate that 68% (n= 39/57) of monkeys in this population used a cup (a plastic slip cap) toContainfood, and a subset of these monkeys, 10% (n= 4/39), also used a cup toContainwater. Cup use was optional and did not replace, but supplemented, the hand/arm‐to‐mouth eating and direct valve drinking exhibited by all members of the population. Strategies monkeys used to bring food and cups together for food processing activity at preferred upper‐level perching areas, in the arboreal‐like environment in which they lived, provides evidence that monkeys may plan food processing activity with the cups. Specifically, prior to cup use monkeys obtained a cup first before food, or obtained food and a cup from the floor simultaneously, before transporting both items to upper‐level perching areas. After food processing activity with cups monkeys rarely dropped the cups and more often placed the cups onto perching. Monkeys subsequently returned to use cups that they previously placed on perching after food processing activity. The latter behavior is consistent with the possibility that monkeys may keep cups at preferred perching sites for future food processing activity and merits experimental investigation. Reports of spontaneous tool use by squirrel monkeys are rare and this is the first report of population‐level tool use. These findings offer insights into the cognitive abilities of squirrel monkeys and provide a new context for behavior studies with this genus and for comparative studies with other primates. Am. J.
