In the end, chimpanzees hunt for selfish reasons, and they don’t always like to share. Finally, he will give them some meat just to be left alone. Other chimps have to beg and harass him to share. This means that individuals will cooperate during hunting to improve their own chances of getting meat.Ĭhimps use information about many things to decide when to cooperate: What is the forest like? How hard will it be to follow the monkeys? Can I catch one on my own? How much energy do I have? Who else is in my group? Are they good hunters?Įven when a chimp catches a monkey, he doesn’t always like to share. Meat provides important nutrients for chimps that are rare in plants. Humans and chimpanzees both hunt animals for meat. One of the earliest and most significant discoveries made by Jane Goodall was that chimpanzees hunt for and eat meat. 33 prey per year during a 10-year period. Jane Goodall’s original tale of chimpanzees still astonishes today National Geographic revisits Jane Goodall’s iconic 1963 article about the chimpanzees of Gombe Stream Game Reserve. Today, researchers study how chimpanzees cooperate with each other during hunting and other activities. One community of chimpan- zees in Gombe Stream was observed to hunt. Like humans, chimpanzees hunt other animals and even go to war with other chimp groups. When Jane Goodall went to study chimpanzees at Gombe, she learned that this wasn’t true. Researchers used to think that humans were the only primates that were violent. This monkey is now lunch for the chimpanzees. Most of them escape, but one isn’t so lucky. More than 45 years ago, primatologist Jane Goodall observed wild chimpanzees making and using tools a finding that dramatically changed the field of primate research. One of the chimps starts climbing up the tree. Suddenly, the air is filled with high-pitched chirps and squeaks-alarm calls! A group of chimpanzees has appeared below the monkeys’ tree. They jump from tree to tree to find the tastiest leaves. JGIs conservation efforts have been focused around Gombe National Park and western Tanzania, where Jane Goodall first started studying chimpanzees in 1960. A group of colobus monkeys are chewing on their lunch.
