Chimpanzee baby dead1/16/2024 That’s typical of their nature, which includes endlessly shifting alliances that break up and re-form, depending on who’s getting on with whom, who’s rising in the hierarchy, who’s in, who’s out – just like office politics among us human great apes.Īnd males can be violent with babies who are not their own. The zoo added that the chimpanzees live in “fission-fusion” groups. That’s certainly true, as we’ve just seen from the horrific attack that took place last week at a sanctuary in South Africa. “Chimpanzee behavior can sometimes be aggressive and violent.” “Policy does not allow staff to enter the same space as these animals,” they said in a statement. Zoo officials say there was nothing they could do. “Those of us that were near the compound were like, ‘My God, why aren’t they going to do something about this?'” Times, after demanding that the mayor launch an investigation. She noticed that trouble was brewing in the form of a 10-minute tussle between chimps, one of whom seemed to be trying to protect Gracie, the mother, and her baby. County’s Quality and Productivity Commission, says she was at the zoo a few days earlier. Zoo patron Victoria Pipkin-Lane, who is director of L.A. We hope these objective accounts will continue to accumulate and eventually allow researchers to take a comprehensive look at the extent to which nonhuman primate understand death, and how they respond to it.Los Angeles Zoo officials insist that when a big male chimpanzee killed a three-month-old baby chimp last week, it was just, so to speak, one of those things. 'These data contribute to a small but growing body of data on how nonhuman primates respond to death. The current research complements these observations and sheds new light on how chimpanzees might learn about death. Previous reports have documented chimpanzee mothers carrying their deceased young for days or weeks, demonstrating that the severing of the mother-infant bond is incredibly difficult for chimpanzees. 'Whether a viewer ultimately decides that the chimpanzee is mourning, or simply curious about the corpse, is not nearly as important as people taking a moment to consider the possibilities.' 'The videos are extremely valuable, because they force one to stop and think about what might be happening in the minds of other primates', Cronin says. But they largely refrain from interpretation, while providing extensive video to allow viewers the opportunity to judge for themselves what chimpanzees understand about death. The MPI researchers therefore believe to have reported a unique transitional period as the mother learned about the death of her infant, a process never before reported in detail. Nearly nothing is known about how primates react to death of close individuals, what they understand about death, and whether they mourn. The next day, the mother was no longer carrying the body of the infant. She remained near the body for nearly an hour, then carried it over to a group of chimpanzees and watched them investigate the body. After carrying the infant's dead body for more than a day, the mother laid the body out on the ground in a clearing and repeatedly approached the body and held her fingers against the infant's face and neck for multiple seconds. The close relationship between the mother and offspring continues for several years after weaning, and is one of the most important relationships in chimpanzee life.Ĭronin and her colleagues observed the behaviour that a female chimpanzee expressed toward her 16-month-old infant who had recently died. Mark Bodamer, a professor of Psychology at Gonzaga University in Washington State, USA.Ĭhimpanzee mothers typically are in close contact with their offspring for several years, carrying them almost continuously for two years and nursing until they are four to six years old. Katherine Cronin and Edwin Van Leeuwen of the Max Planck Institute for Psycholinguistics collaborated with Innocent Chitalu Mulenga of Chimfunshi and Dr. The research team conducted their observations at Chimfunshi Wildlife Orphanage Trust in Zambia, where wild-born chimpanzees who have been rescued from illegal trade live in the largest social groups and enclosures in the world. Their commentary appears online in the American Journal of Primatology.
