After a rollercoaster life, Dorothy died at a chimpanzee rescue center in Cameroon. This photo, showing her chimp family observe the burial, went viral on the internet and raised the question, can animals really exhibit funeral behavior?
Dorothy's mother was killed by hunters. They then sold her to an amusement park in Cameroon where she was chained to the ground and taught to drink beer and smoke cigarettes for noisy crowds. Poor diet and lack of exercise made Dorothy obese. In May of 2000 she was brought to Cameroon's Sanaga-Yong Chimpanzee Rescue Center and rehabilitated. She became a favorite at the center and even mothered a child of her own. But in September of 2008 she died of congestive heart failure. The management let her chimpanzee family witness the burial. “Some chimps displayed aggression while others barked in frustration,” a worker who photographed the event later explained. “But perhaps the most stunning reaction was a recurring, almost tangible silence. If one knows chimpanzees, then one knows that they are not usually silent creatures.”
The photo of the chimp funeral went viral on the internet and was published in the November 2009 issue of National Geographic. It shows Dorothy under a light blue sheet in a wheelbarrow being pushed to the burial site by a park worker. Another worker holds Dorothy's head gently in her hands. Behind a fence in the background are more than a dozen chimpanzees, staring intently, looking visibly sad. Chimpanzees, along with African elephants, ants and magpies are some of the few animals known to exhibit funeral behavior. Interestingly, they are all social animals. “Perhaps their grief reactions function as a social signal that allows for reshuffling of status relationships, facilitates filling of the reproductive vacancy left by the deceased, or fosters continuity of the group,” speculates Janis Dickinson, of Cornell's Ornithology Lab, in an essay on yellow-billed magpies.
