Scientists first witnessed a chimpanzee killing a gorilla in two shocking attacks captured in a video in Gabon’s national park on the west coast of Central Africa.
Researchers at the University of Osnabrück and the Max Planck Institute for Evolutionary Anthropology in Germany followed a large group of 27 people. Chimpanzee (((Chimpanzee) February 6, 2019, when the chimpanzee first observed attacking five western lowland parties gorilla (((Gorilla Gorilla Gorilla) — Three adult females and one toddler led by a male silverback.
Simone Pika, a cognitive biologist and research co-author at the University of Osnabrück, told live science that “Silverback was actually throwing some of the chimpanzees into the air, so he himself and his group. I was really trying to protect it. ” Despite injuring three chimpanzees, the silverback was overwhelmed, and the chimpanzees eventually captured and beat the toddlers in the group.
The same group of chimpanzees attacked the gorilla again in December of that year, killing another infant gorilla. “It teaches us not only about the violent potential of chimpanzees, their diversity of behavior, but also their ability to cooperate,” Pika said.

Chimpanzees and gorillas usually coexist peacefully in the rainforests of Central Africa, where habitats overlap.two Apes According to Pika, the seeds usually avoid each other and eat the same fruit tree without conflict. However, chimpanzees are known to actively protect their territory from other chimpanzees and kill members of rival chimpanzee groups.
The research team was tracking the chimpanzees that caused the gorilla killings as part of a long-term study of chimpanzee behavior in Gabon’s Roango National Park. Chimpanzees were returning from territorial patrols when the first attack occurred.
“At first, I just noticed the chimpanzee screams and thought I was observing the typical encounters between individuals in the neighboring chimpanzee community,” said the lead author, a PhD student at Osnabrück University. Lara M. Southern said. Said in a statement.. “But then, when I heard the gorilla’s characteristic chest beating, I realized that the chimpanzee encountered a group of five gorillas.”
The February encounter lasted 52 minutes, forcing the gorilla to retreat without an infant. Researchers don’t know if the second incident in December involved another group of gorillas.Researchers published their findings in the journal on Monday (July 19) Science report..
Pika can only guess why these unprecedented attacks happened. Chimpanzees may hunt animals such as monkeys and may have had the opportunity to kill small gorillas in search of food. However, according to Pika, chimpanzees did not show normal hunting behavior. For example, they ate only one of the infant gorillas, which was almost completely consumed by one chimpanzee rather than being shared.
Attacks can be triggered by food competition. Competition is fierce in February and December, when the attacks occurred, due to a shortage of chimpanzee and gorilla fruits. Climate change We are also reducing the amount of fruit available in the rainforests of Gabon. This encourages these positive interactions as it can further intensify competition.
The research team will investigate possible causes and continue to monitor chimpanzee behavior. “We still don’t fully understand the behavior of chimpanzees. This is great for me,” Pika said. “We already know a lot about the variety of chimpanzee behaviors, but suddenly they surprise us again.”
