This post is largely the article submitted to, and published in, three KZN community newspapers this past week. Its purpose is to explain the mating season behaviour currently prevalent in Vervet monkey troops, as adult males joust for position and beat off those opportunistic males who want access to females, and to emphasise that this behaviour, loud and apparently aggressive as it is, should be of no concern to humans. It is totally monkey focused:
Steve Smit, joint co-ordinator with Carol Booth of Monkey Helpline, says that many people become very nervous of monkeys when they see the aggression and ugly injuries that are so prevalent during mating season. “But they have nothing to be concerned about”, says Steve. “All the aggression and posturing is amongst the monkeys themselves and does not translate into any aggression towards humans or their companion animals.”
Carol says that at this time of year Monkey Helpline experiences a marked increase in phone calls from concerned members of the public. “They see and hear the fighting, and also see badly injured and bleeding monkeys, and are concerned for the safety of their children and dogs, believing that they too are in danger of being attacked by an aggressive monkey. Fortunately the monkeys are only focused on the issues around mating and status within their troop and have no interest in humans or other animals.”
“We do also get lots of calls from people who are concerned about the well being of the injured monkeys”, says Steve. “ The injuries that some of the monkeys sustain can be extremely bad and to the untrained eye they look life threatening, which they often are. Interestingly enough, most people think that these monkeys have been shot or bitten by a dog. But monkey-inflicted injuries are easily recognized because their razor sharp teeth inflict injuries that resemble a scalpel cut. Once inflicted the injury often gapes and looks very bad. Our dilemma is deciding which calls we respond to and which we don’t. We can’t possibly go out and rescue every monkey who gets injured during these confrontations. We don’t have the capacity to do this, but it is also not always necessary. Monkeys have amazing healing capacity and recover from the most unbelievable injuries. However, we also know that an injury that looks minor can result in an infection, even tetanus, and cause the death of the monkey. It is never an easy decision to make but it is something we do every day. When someone phones in out of concern for a monkey, we have a series of pertinent questions we ask. Based on what we are told we then decide whether to go and carry out the rescue or not. If there is any doubt we will always go out to see for ourselves and then make the decision whether or not we’ll catch and treat the monkey.”
Carol believes that the mating season aggression between urban monkeys is far greater than amongst monkeys living in more natural areas. “Urban monkeys are under ongoing stress because of constant harassment. People don’t realize that monkeys are not invading our living space. Wherever we see them in our suburbs it is because they are in their traditional territory that has been drastically changed by human occupation and development. They have been here for many generations and have been subjected to increasing persecution, both deliberate and unintentional. Destruction of natural habitat, being chased and attacked by dogs, being shot at and chased from one property to the next by homeowners, having to cross dangerous roads, encountering razor wire and electric fencing, and much more has left urban Vervet monkeys on edge, and as a result of this the fights that take place between monkeys are more intense and frequent than would be the case if they were less stressed and had fewer dangers to deal with. Domestic dogs are predators and kill far more monkeys in urban areas than are killed by natural predators in the wild. In urban areas, as monkeys go about their daily foraging, they encounter a lethal predator in the form of a domestic dog virtually every fifteen to twenty meters. Their mortality rate is much higher than would be the case if they were living in a more natural environment, which is why urban troops of monkeys are much smaller than troops in the wild, and are in fact steadily decreasing in size from one year to the next.”
Steve and Carol are heartened by the fact that most people wish the monkeys no harm, and once their fears about monkeys have been allayed they become far more tolerant of the presence of these little animals. “Very few people actually wish monkeys any harm, and even fewer still will deliberately harm them”, says Carol. “We offer free advice to anyone who is having problems with monkeys around their home or at schools, etc, and we do many educational talks throughout the year. Monkeys are amazing animals and it takes just a little time and effort to ensure that they are not an intolerable nuisance. What monkeys need more than anything else is your understanding of who they are, why they behave the way they do, and what you should and shouldn’t do when they are around.”
Both Steve and Carol ask that members of the public understand that they are full-time volunteers doing this work out of love for monkeys and also to help people who are experiencing “problems” with the presence of monkeys.
