Recently Colobus trust wrote about finding a new hybrid species. This was believed to be a mix of vervet and sykes monkeys. The picture we posted belonged to Yvonne A. de Jong & Thomas M. Butynski, since then the Colobus Trust team has been out on a number of occasions trying to learn more about these creatures.
When I first heard about these animals, to be honest, I didn’t believe it. Normally sykes and vervets don’t like to interact very much. Opposed to Colobus who do not eat the same foods, these animals do have a lot of competition for food. It is not unusual that they would live in the same area. But for them to be in such close proximity to one another that mating begins to take place is a sign of something. I believe this has something to do with the loss of natural habitat in Diani putting these animals in much closer proximity. Until I saw these new pictures I believe you could have made the argument that this was just a funny looking skyes monkey. What is very interesting to us is that the testicles of this animal are blue. This is a very specific trait of the veret monkey and not sykes. With this evidence there is no doubt in my mind now what we are looking at. This is indeed a hybrid and we are very excited to share these photos with you today.
We have been spending much more time with these animals in the last few weeks trying to gather as much information as possible. We have confirmed two individuals but know that there are at least 5. The one we followed on this day was hanging out with a group of sykes. Although he was positioned on the outside of the group, he seemed to display some of the dominant traits. The other monkeys stayed out his way and on a few occasions he approached our team a bit aggressively. It is a common belief that when these two animals of different species mate the offspring will be unfertile. The question then arises why are there so many and have they formed a troop of their own? These are things we here at the trust are looking into. We look forward to collaborating with other researchers such as Yvonne A. de Jong & Thomas M. Butynski on this subject. The Colobus Trust will keep you updated on what we find as well as any information about where other incidences such as this may have happened before.
