日本猕猴（Macaca fuscata）的甘薯洗涤和小麦砂矿开采是非人类动物当地传统的最著名例子之一。这些行为的功能以及这些行为的习得和传播机制一直是人们争论的焦点。根据动物管理员的报告，莱比锡动物园的大猩猩[黑猩猩（Pan troglodytes），倭黑猩猩（Pan paniscus），大猩猩（Gorilla gorilla）和猩猩（Pongo abelii）]偶尔会清洗食物，我们进行了一项由两部分组成的食物清洗行为研究。在第一部分中，我们评估了目前的分布的基础上，看护报告的行为。在第二部分（实验）中，我们分别为受试者提供了一个水盆和两种食物（苹果和谷物），这些食物要么是干净的，要么是用沙子覆盖的。我们发现，所有物种的受试者（大猩猩除外）在食用苹果之前都会将苹果放在水中，而且当苹果脏的时候，他们这样做的频率要高于干净的时候。一些黑猩猩和猩猩也从事类似于小麦砂矿开采的行为。
Sweet potato washing and wheat placer mining in Japanese macaques (Macaca fuscata) are among the most well known examples of local traditions in non-human animals. The functions of these behaviors and the mechanisms of acquisition and spread of these behaviors have been debated frequently. Prompted by animal caretaker reports that great apes [chimpanzees (Pan troglodytes), bonobos (Pan paniscus), gorillas (Gorilla gorilla), and orangutans (Pongo abelii)] at Leipzig Zoo occasionally wash their food, we conducted a study of food washing behaviors that consisted of two parts. In the first part we assessed the current distribution of the behavior on the basis of caretaker reports. In the second (experimental) part, we provided subjects individually with a water basin and two types of food (apples and cereal) that was either clean or covered/mixed with sand. We found that subjects of all species (except gorillas) placed apples in the water before consumption, and that they did so more often when the apples were dirty than when they were clean. Several chimpanzees and orangutans also engaged in behaviors resembling wheat placer mining.
