What’s happening to the chimpanzees of Uganda?

30 07 2007

As a child, most of the images I saw of chimpanzees (Pan troglodytes) on television primarily focused on grooming and other social interactions. It was not until years later that I actually saw footage that I can’t help but find disturbing; chimpanzees hunting, and eating, monkeys. Even though I know better than to try and push my morality on apes, it still remains to me a brutal sight. Recent documentaries, like the BBC’s Life of Mammals, have taken a more balanced look at the cooperation and competition amongst chimpanzees, but it was not until I picked up Franz de Waal’s Our Inner Ape that I heard of chimpanzees that hunt humans. The subject is not covered in much detail, de Waal primarily states that such “interactions” occur and that human parents are helpless to protect their children from chimpanzees without firearms or other weapons, but I was intrigued by this story and trawled the internet to find out more. What is happening in Uganda that led to the chimpanzees there becoming so aggressive?

[Note: I realize my comments about chimpanzees being represented as kind/benign echo those found in the beginning of the book Demonic Males, but given that I only picked up Demonic Males after I started writing this post, my comments are merely a case of convergent intellectual evolution of an argument.]

In January 2004, the magazine BBC Wildlife devoted an article to the strange of horrific behavior of the Uganda chimpanzees, noting that there had been at least 15 attacks on human children during the seven years prior. One of the most recent, occurring in 2000, was carried out on the child of Anet Alikiriza, her child dying from injuries caused by the attacking chimpanzee;

“The chimp ran much faster than I could,” Anet said. “It grabbed my leg, and I fell hard. Then it took my baby.” The chimp dragged the child down the trail and into the bush. By the time a man arrived to scare the animal away with a spear, Anet’s baby had suffered horrific injuries, and died in hospital a week later. Anet and her mother abandoned the fields near the lake in fear of another attack and later sold the land to pay for the large debts incurred from their trip to the hospital.

According to another article featuring the same story, “By the time help was summoned and the chimp was chased away by a man armed with a spear the baby’s nose and upper lip had been eaten away.”

While such attacks are chilling, there does not seem to be a chaotic epidemic of attacks where chimpanzees have developed a desire for human flesh; much like shark attacks, these incidents seem to be rare and have little to do with territoriality. While it is disturbing to think that chimpanzees do not see human babies as any different from the colobus monkeys or other prey they normally pursue, the way in which the chimpanzees capture and consume the children reflects that such encounters are predation events, not aggressive murders. As with many other animals that live in areas under pressure from habitat destruction, the Ugandan chimpanzees are continually having to cope with reduced habitat and reduced resources, human habitation existing right on the edge of the parks. In other mammal species, like Asiatic Lions, dry years that result in less resources for lions in a given area cause young males to have to search further for food when they are kicked out of their pride when reaching maturity, and the further afield they have to go for food the more likely they are to come in contact with farmers. While a similar pattern might hold true for some cases (I am far from familiar with every chimpanzee attack known), chimpanzees have an advantage that lions do not have; they can eat a wider range of foods and make use of a larger number of resources, and in many cases the attacks do not seem to be carried out by “rogue” chimpanzees that have been ostracized from a group. Instead, it appears that people are pushing into chimpanzee habitat, and when people enter the habitat chimpanzees do not grant people any special allowance; while they likely recognize the difference between a colobus monkey and a human baby, they do not grant human children any special privilege.

The fact that encroachment and habitat destruction leading to increased contact isn’t widely accepted by all, however. Some rather fanciful reports have been issued suggesting that the chimpanzees are getting drunk of illegally brewed beer, and a drunk chimpanzee will not hesitate to attack a human. Others, like Pan African Sanctuaries Alliance secretary Doug Cress, maintain that the chimpanzees are exhibiting a “fear reaction” to habitat destruction, again trying to remove human predation from the suite of “normal” chimpanzee behavior. Indeed, Uganda does not want any bad press concerning its great apes (a major draw for tourists), and so it seems that many Ugandan wildlife officials or agencies would rather paint the incidents as freak accidents outside the realm of normal behavior for the animals than as a real problem that is likely to come up over and over again anywhere that chimpanzees and humans live in close proximity without barriers.

Indeed, the natural behavior of these chimps, whether a result of hunger from reduced resources of mere opportunity (chimpanzees can easily overpower even fit young human males), is highly disturbing. Still, as seems to often be the case, it is those most affected by such tragedies that are overlooked. As recalled before, Anet Alikiriza not only lost her child but her farm due to debt from medical bills accrued at the hospital. Farmers on the edges of parks in which chimps live, even if not attacked, also pay a price. From the BBC article;

The boys’ father complained bitterly about the chimp and its intrusion on their lives. The trouble had started eight months before, when the clearing of the forest for the tea estate got into full swing. “It has not killed anyone here,” he explained, ” but it chases people and eats our crops. My wife and our sons, they can’t go to the field. We need that field for food, but we will have to let it go.”

And so the poor are once again stuck in the middle. They are inhibited from earning a living for themselves because the land that they have encroaches on chimpanzee habitat, some of the children are killed (some even stolen from their beds at night, as the chimpanzee Sadaam repeatedly did), and those that are only injured require so much medical care that the families are driven into debt. I am not an expert, but I know of no assistance or compensation plan for the families, and often times problem chimpanzees are left alone to continue to harass and even attack people as they are only doing what is “natural.” This is obviously a very sticky socio-political area, chimpanzees being so like us and important to the tourist trade, but at the same time the problems of the poor apparently are not addressed at all. While “alternatives” to euthanizing chimpanzees might sometimes be discussed, I can’t think of many that would really be effective; relocating a problem animal would likely result in it coming right back within a certain amount of time, and given that the attacks on humans are an extension of natural predation behavior, there is no way to inhibit a chimpanzee from doing it again.

Accounts of chimpanzee attacks on humans are not restricted to Uganda, however; in 2002 Frodo, the leader of a group of chimpanzees that Jane Goodall was studying in Tanzania’s Gombe National Park, stole a 14-month-old child from two women traveling in the park, killing and partially consuming the child. A dispassionate report on the attack was published soon after it occurred, suggesting that it was the fault of the women traveling in the park for not respecting the power and aggressiveness of chimpanzees. Although the park staff considered euthanizing the alpha male, seemingly no action was taken, Frodo even receiving medical assistance when suffering from intestinal parasites (I assume the assistance was granted by members of Jane Goodall’s camp). Other attacks are known from various locations from the 1950’s at least, although I have been unable to find any references to the attacks specifically, some even insisting that the attacks are a relatively new and aberrant phenomenon (which I don’t believe for a second).

Some scientists are looking beyond the horror of the situation to potential implications for disease, however. It has long been known that disease can easily travel from apes to humans because of the bushmeat trade, apes being killed and consumed by various people in Africa. Now that we know that chimpanzees sometimes consume humans, it could be possible that microbes in our bodies could more easily pass into chimpanzees. Unfortunately I do not have access to the article, but the described behavior could have very important implications when it comes to disease and conservation.

So what can we conclude? Here in the U.S. chimpanzees and other primates are often tortured and mistreated in the name of medical or scientific “progress,” but in reality (or at least in the wild) chimpanzees are not simply benevolent “forest people.” No, their societies are often violent, males and females both carrying out various atrocities in addition to the more peaceful bond-building that goes on every day, just like us. Although males of both species are often singled out as being the most violent, females too are capable of terribly acts, namely infanticide (this recent article on chimpanzees and one of today’s headlines reveal that it is not only males that are prone to violence). I am not sure, however, if chimpanzees that are a continual problem, raiding houses at night or continually attacking children, should be given an excuse because they are so close to us. In places like Florida, alligators over a certain size are shot every year in order to ensure that large crocodilians do not show up in people’s backyards, and we have no problem with killing spiders or insects that might do us harm of discomfort. Even amongst mammals, the reintroduction of wolves to Yellowstone still seems to be controversial, the image of the wolf as evil dying hard. Chimpanzees in Uganda, however, seem to have more of a special status, and it might even be considered murder to kill one that has repeatedly harmed children (even though we don’t wish actually give them anything close to human rights in Western society). This problem likely stems from the multiple public faces of the chimpanzee; the clown, the animal, the ancestor, and the demon, everyone having their own combination of these traits that molds our beliefs as how to react to them. What the solution is to the problems in Uganda, I don’t know, but I do feel that the troubles of the poor are being overlooked in favor of often-idealized animals and tourism dollars, a problem that there is no excuse not to rectify.

So it is actually identifiable individuals that are more likely to attack humans? After all, euthanasia is only worthwhile if it actually reduces the risk. Whenever we hear of a shark or crocodile attack, there’s always someone who says that the shark or croc that perpetrated the attack needs to be eliminated so that it doesn’t happen again. I’ve always felt that this would be pointless, because an individual shark is not going to be ‘targeting’ humans as such, just opportunistically taking a potential prey animal that happened to wander by when it was hungry. The only time euthanasia of the individual is perhaps worthwhile is if the attacks occur in an area with a high human presence and where the predator species is not normally found. Are the individual chimps actually targeting humans more than any other prey animal? Will killing the attacker actually remove the risk, or will another individual move into the vacated territory and be just as likely to attack humans as the euthanised individual?

All good questions Chris, and I didn’t attempt to answer them in the post because I honestly don’t know. Like I suggested, the predation on babies seems to be part of the natural behavior of some of these chimpanzees, but there are specific individuals who seem to be more prone to the attacks than others (like Kiki and Sadaam, especially). Part of the dividing line in problem animals is whether they consume their victims or not; when sharks attack they typically release the victims immediately as humans are not their regular prey. Crocodiles and chimpanzees (apparently) consume their victims, (at least partially) and may do it again. In cases where crocodiles and other animals that have killed and eaten humans, the offending animal can sometimes be identified and is usually killed. I know of no such procedures for chimpanzees, even though they are doing little different from what the crocodile does.

I think that the situation in Uganda can be managed through education and proper land management, but I really feel sympathetic towards those who have lost children (or even more) to chimpanzee attacks, especially since their own government seems to deny that such occurrances are real and the people seem to get little assistance to pay the medical bills. The situation needs to be monitored carefully, however, and if there are specific chimpanzees that are regularly taking children and eating them, then (as distasteful as it may be) then perhaps those chimpanzees should be euthanized. Still, I know that the attacks will not simply stop and as people continue to move in closer, attacks may become more prevalent (perhaps hitting a peak when resources for chimpanzees crash).

First these are Jane goodall sponsored chimpanzees. Second the chimpanzee that attacked and killed the infat child snatched from the woman that particular chimpanzee was Frodo, a Jane goodall chimpanzee wth a long history of horrible aggression towards other chimps right from his infancy he was aggressive but he is most aggresive towards humans. Goodall and her ilk continually blame humans for this phenomina. My question to you is, why was this Frodo chimpanzee and the other chimpanzees that have attacked and killed or maimed children not hun ted down and killed? Well the answer is so obvious, these animals are Goodalls chimps and therefore untouchable. Where I grew up we would hunt down any wild animals that killed our livestock or a person and we would kill them. No cries about “animal rights” no snivelers from peta, nope track the animal and kill it. simple. But these attacks will continue until the villagers themselves decide to take matters into their own hands and they hunt all the chimpanzees down in the area and wipe the animals out. Totally! This includes the ape rescue centers, I say this because a group o chimpanzees escaped a “sanctuary” and went on to attack a car full of tourists on a public road and these animals maimed one fellow and hunted down and tore another man to pieces. What galled me bitterly was when the “primatologist” was describing the attacked they smirked when they described how the man had no chance whatsoever against the chimpanzees!! Oh no wipe the chimpanzees out in the area all of them infants too kill all the filthy aniamls!

I think I may know whats wrong with them.You see chimps have emotions and a memory like humans.They are probably tired of seeing their homes cut down and their fellow chimps captured for animal testing facilities and such.Yea,yea I know what you’re thinking;”PETA!” and “Your just a animal rights activist!”.

What an excellent arcticle! Going by the comments there are people who do ascribe to the theory that it is the Humans Fault. I would venture to state these apes are ultra aggressive thanks to the ape rescue centers that follow Jane Goodalls example turning these highly dangerous animals into very dangerous pets. I state this because these centers rescue infant apes and then try to cross foster them diapering them treating these animals as human infants, cooing and coddling them administering medicines, feeding them etc. Any anthropologist will tell you when two alien cultures meet one culture will be destroyed by the dominant one. When Goodall began her work the chimps avoided her like the plague (smart apes) acting naturally. When she began to feed these animals on a daily basis to entice them closer she began the alteration of these animals. The apes abandoned thier natural instinct to forage for food no longer freely roaming to eat, and the adult mother did not teach their infants to forage. Jane Goodall by her erroneous actions had made these chimps dependant on humans for food,thus began the alteration of the true apes nature. Her chimpanzee Frodo should have been put down early for the unabated aggression he displayed from infancy, but Goodall did not do so and it has cost a blameless human thier life. To blame the people living there is the height of stupidity and hatefulness propogated by unbalanced animal lovers. These agressive apes should be hunted down and killed. To blame the dirt poor people of these areas is such an insult. The ape workers are continually telling the natives how to live how to eat, the anti government (thier longsuffering hosts) poison they spout is beyond the pale. What arrogance! It disturbs me greatly to watch as the ape workers seemingly place the lives of apes above humans. By this I mean the fact that the apes recieve medicines, oxygen, trips to human hospitals ugh, they get better treatment than the dirt poor natives get. Apparantly someone took matters into thier own hands and set fire to a chimpanzee night enclosure. One chimp died in the fire and another lasted about a week ad passed away. The arsonist was never caught, but the message was clear. Go to J.A.C.K. site and read the outpouring of grief, its like the Pope died or something. my point is apes are of more value than human beings and that is so very wrong. To compound the error there are sites that make captions under photos that are twisted into the pity this infant…chimp bonobo gorilla orangutan. eg; Karl ammann has an ape smuggling video he secretly taped(supposedly) and his voice over drones “Look at this man kicking and taunting the baby gorilla” when the video shows the tiny gorilla trying to clutch the mans leg to climb up on him, the man suspends the gorilla by the line it is tethered to and gently moves the baby(upside down due to the line around its waist) away from him and gently sets it down. No kicking of anykind no taunting or harm to the baby. And yet Ammann manages to infuse his slanted view so effectively that in the comments below a writer states “did you see that man kicking that baby gorilla? how horrible!” Please watch the clip on youtube, and others and you will see the false claims made by people who infuse their own view into this presentation. This is why I cannot support any of these places. It has become an industry in of itself. Take the example of Orangutan island. Since this rescue center opened not one single orangutan has ever been released, but the orangutnas just keep pouring in. Despite the claims in their literature they do not release the apes back into the wild, the apes are shnted to a protected island where they are still fed still medically looked after, and they reside in groups totally against the solitary animals nature. These orangutans if released into the real wild would not survive thanks to the humans crossfostering them, back to raising them just like human infants diapered regular health checks bathing them unnaturally in sinks and giving them cutesy names, in other words just pets. Thats all just pets. Yers as far as I am concerned, this is an industry which to date has raised millions to put on vey slick media presentations yoiu know holding up a screaming chimp baby claiming this infant is truamatized by seeing its family slaughtered it would die a horrible death if you do not support us now with your donations. Talk about emotional blackmail Fuck these centers fuck these apes, lets get back to saving human lives. Do you think for one moment that a starving people would not kill apes to eat them? I would to feed my family dammed right. I have been watching the ape saving videos, and the bullshit s overwhelming(back to the industry)

Is it possible that, like humans, some chimps are psychopaths?

But, consider this, whaqt if you added a littl content?
Iain’t suggesting your information is not solid, however what iif youu added a post title thatt makes peopple want more?
I mean Whats happening to thee chimpanzees of Uganda?

| Laelaps is kinda boring. You could glance at
Yahoo’s front page and seee howw they write post titles to get viewers to click.

Yoou might add a related video or a pic or two to grab
people interested abou what you’ve written.
