Why Do Chimpanzees Throw Poop? 黑猩猩為什麼要丟大便？
Going to the zoo can be a great adventure, especially if you find poop hurtling in your direction. The likely perpetrators, chimpanzees, are known to sometimes throw their feces at visitors.
Throwing feces is not a regular occurrence for primates, at least not most of them. Primates in the wild don’t normally throw feces. It’s typically observed only in captive populations of chimpanzees.
Chimpanzees have hierarchical social groups. They are known to drag tree branches or throw rocks when they are frustrated or annoyed or when they want to display dominance.
In zoo environments, especially if groups of people are staring at them, the chimps may get riled up or frustrated, and they may decide to convey that emotion to their captive audience.
Since they’re usually deprived of rocks, or branches, or any small objects like that, for this exact reason, they opt for the next best thing that they have within reach, which is usually poop.
