This attention is giving Kibali more confidence and a keen interest in mating. Some of the younger females in the group are changing their allegiance to one of our young virile males, Kibali. What’s happening with the TZ chimpanzees? You will see the females and subordinate males grooming Jambo as a pledge of loyalty to his role. He is a good leader and makes sure everyone stays in line but never gets too involved in the petty squabbles in the ranks underneath. Jambo is our dominant male (you will recognise him as he is the one with no hair due to alopecia) and up until recently has gone unchallenged. Our chimpanzees were moved over to their new home around a month ago and have been settling in fantastically well and loving their new space, moving higher than they have ever been able to before on webbing made to move like real trees. This was the drive behind our recently opened £3.5million habitat, Chimpanzee Eden. We have spent years running an award winning rewilding programme for our chimpanzees and ensuring that they live in as natural environment as possible, with as close to normal wild behaviour. The leader of the group can change and the challenge for this position usually comes from a younger, more virile male or a group of them. However, the leader isn’t a democratically elected one but a role won by some fighting and creating enough allies as back up, as well as being powerful and wise to convince all the rest of them to follow. A bigger group is usually made up by smaller subgroups and these groups are constantly changing. This male will play a vital role in keeping the group settled as well as offering protection when needed. Forging friendships, creating alliances and having the occasional spat is normal for chimpanzees and part of their complex social needs, and like us they rely on these relationships to thrive and indeed survive.Ĭhimpanzees live in a complex society and each community of chimpanzees will have a dominant male. Much like us, our close cousins revolve their life around socialising. We also wanted to take the time to explain what is happening currently within our group of chimpanzees. We want to reassure you that all of our chimps are doing well and are always being closely monitored by our expert team. Upon recent visits to Twycross Zoo you may have noticed arguments amongst our chimpanzee community. "There's an aggression toward individuals that are not in their group."īut chimps are often seen as friendly and cute animals because many facilities use preventive measures to prevent the aggression, he said.Jambo the chimpanzee and the challenge for power Think being a human is difficult? Try being a chimpanzee! "They can adapt very well to their environment but that doesn't preclude that they are territorial and they are violent and wild animals first," Ross said. The emotional impulses also play a role in how aggressive they can become, he said. They directed the violence towards Andrew whom they feel was infringing on their territory."Ĭhimpanzees have a wide range of emotions and they are similar to what humans experience, yet they are known to have erratic and unpredictable impulses, Ross said. "This is why we come to the conclusion, as far as our expertise goes, that it was a territorial defense. "They have no anger," Cussons said of the chimps. The two chimps saw Oberle's crossing the fence into the chimps' space as a violation of their territory, prompting them to take action, Cussons said. In Thursday's case, however, an internal investigation by the Jane Goodall Institute near Johannesburg showed that the chimps might not have intended to be malicious, Eugene Cussons, director of the institute, told "Good Morning America" today. Such physical lack of control can potentially lead some chimps to become more aggressive when physical. As a result, sometimes chimps use more of their muscle strength than necessary, according to Walker's theory, published 2009 in the journal Current Anthropology. In chimps, the muscle fibers closest to the bones - those deemed to be the source of strength of both chimps and humans – are much longer and more dense, so a chimp is able to generate more power using the same range of motion, Ross of the Lester Fisher Center said.Īlso, unlike humans, chimpanzees have less control over their muscles. Research suggests the difference in strength between the two lies in the muscle performance. Indeed, chimpanzees have been shown to be about four times as strong as humans comparable in size, according to evolutionary biologist Alan Walker, formerly of Pennsylvania State University.
