The Angolan Black and White Colobus Monkey (Colobus angolensis ssp palliatus)

Since I spend most of my time following the Angolan Black & White Colobus monkeys of Diani I thought I would introduce them to you in more detail.

Angolan Black & White Colobus Monkey

Habitat & population:

I am following a sub species of the Angolan Black & White Colobus monkey (Colobus) Colobus angolensis ssp palliates (Family Cercopithecidae: Subfamily colobinae). Previously found along the entire coast activities like deforestation and hunting now mean they are only found in the south eastern part of Kenya and Tanzania coastal forests. There are estimated to be between 2 - 5,000 Colobus monkeys in Kenya and the latest census conducted by Colobus Conservation found there were approximately 450 individuals living in the Diani area. This is an increase on previous years and is also a good sign of the general health of the forest.

Anatomy:

This species of Colobus monkey have black hair with a white brow band, cheeks and throat. They also have long haired white epaulettes streaming from their shoulders. The lower part of their tail is white and for males they have a white line from their buttocks to their penis where females just have a white patch by their buttocks. Colobus babies are born white and then turn grey and black, it is not till around three months old they get the adult colouration of black and white.

All Colobus species they are diurnal (active during the day), they have flattened nails, pads on their buttocks and their hind legs are longer than their fore limbs. They have a light-weight bone structure and elongated limbs as they spend their entire lives in the trees (arboreal), so this makes it easier for them to leap from tree to tree. They have four digits on their hands and do not have thumbs, however, on their feet they have five digits retaining their opposable big toe. The reduction of a thumb on their hands is thought to aid their movement through the forest. The name “Colobus” is thought to come from the Greek word “kolobus” meaning maimed or mutilated, due to their lack of a thumb.

Diet:

The Colobus monkeys are specialist leaf eaters, occasionally taking in fruits and flowers and do not have cheek pouches. Their stomach is very large and has three separate chambers with specific bacteria that help to ferment and digest the leaves, very similar to the process of rumination in cows. They have been recorded to eat 46 different species, but only five species make up the greatest proportion of their diet. Due to the poor nutritional quality of their food they have to browse for many hours, consuming two to three kg of leaves per day (one third of their full body weight). This means they have to sleep for around a third of their day to aid the digestion. They even eat soil, clay, charcoal and rocks which is thought to assist in the digestion of toxic leaves.

Social Structure:

Groups are normally made up of one male and many females with between 3-25 individuals in well defined territories. The dominant male will protect the group from predators and rival groups whereas the dominant female will lead the group. Females remain in their natal troops for life while young males will leave their natal group to start bachelor groups, or to travel alone until they are able to take over their own group. Colobus reproduce all year round with a peak in September and it is thought the babies are born white to encourage other females of the group to take care of the infant; ‘aunting behaviour’. This will not only free up time for the mother to rest and feed, but allow the younger females a chance to practice mothering skills for when they have a baby.

In Diani the Colobus are not a pest to tourists as they are not interested in human food and spend their time in the trees and not on the ground. For this reason they are well liked by visitors and the local people and see as a sign of health in the forest.

Kenya one month on, the journey continues.

Wow, it has been one month since I left the UK to begin my adventure in Kenya, where has that time gone?

What a month. It has been incredibly hot everyday (pretty sure it’s never dropped below 28 degree Celsius even at night) and I have sweated more than I thought humanly possible. Having a pig rub up against me while looking for the colobus monkeys in a private residence was interesting. Being attacked by a turkey that I think has masculinity issues was definitely a thrill ride I will not forget in a hurry. Same as ridding on Matatu’s, which are pretty much old beaten up mini-buses with parts missing, more people than seats crammed on, loud reggae music and many stickers obstructing the drivers view with Islam messages like ‘God is great’ or Bob Marley saying ‘One Love’. Was really funny when the driver went over a speed bump and the engine cut out; with a resounding cheer from the passengers. Oh and the conductor who takes the money (16p a ride) hangs outside the side door with many notes between his fingers whistling at anyone to get them on board. Matatu’s have been banned driving at night after too many accidents; don’t worry Mum I am being careful.

The pig that kept very close to me

I have enjoyed swimming in the warm sea as much as possible and relaxing on the golden sand beach. I have now bought a snorkeling kit and swam out and saw some coral and clown fish (Nemo), zebra fish and other colourful individuals. Can’t wait to take a boat further out to the reef close by and then go to a marine park area when my family arrive in June. 

Watching monkey autopsy’s being carried out by Martr the volunteer vet was very interesting, taught me a lot about their anatomy and there strange circle shaped hearts; no one knows why this is. With the work of Colobus Conservation the amount of monkey injuries has drastically dropped, due to initiatives like power cable insulation, planting of more native trees and Colobridges going over the main road.

The cherry on the cake though has been having hundreds of primates all around me all the time; they are part of the landscape and that is fantastic. You have the Angolan black & white colobus, the Sykes and Vervet monkey as well as the Yellow Baboons, and then at night you have the Bush Babies making some interesting noises. The different characters of the species are really fun to watch; they will be covered in future blog posts. However, I think it is clear that the Sykes are definitely the funniest to watch with their glowing eyes and bobbing heads.

The baboons have a powerful odour to them and roam the floor in large groups like the school bullies seeing who they can pick on (it usually ends being their own group). Being in the middle of a Baboon/Dog/Human firing rocks via catapult battle was pretty hair raising, but I live to tell the tale; well that was pretty much the tale.

When I am walking round a lot of the locals recognise the colobus T-shit and shout ‘COLOBUS’ at which I say back ‘Jambo’. It could be my red backpack and blue clipboard that gives it away more; they have kind of become my trademark items now. Speaking of Jambo my Swahili is coming on well and although I can’t string loads of sentences together I know most of the useful words, greetings and how to tell people trying to sell me things, ‘No I do not want it thank you’ or ‘Hapana sitaki asante sana’.

All in all I have now settled in very well and although the heat is on average 32/33 degrees Celsius I am being told the rains are coming in soon and the temperature will drop; admittedly only to around 28/29/30, but it will be a welcome change. Oh I nearly forgot, I watched the sunrise a few days ago and it was simply magical, a picture just can't do the moment justice, but I tried.

Update from a primatologist in Kenya - I have arrived!

It's not every day you get chased by a Turkey while trying to look high up in a tree to identify a monkey with the baking hot African sun beaming down on you; or maybe it is?

Catch up:

For those of you that don't know I am now living in Diani Beach, Kenya working as a Field Researcher for Colobus Conservation. This is to gain experience working with wild primates and what the life of a researcher is like. I am here for six months and on my return will begin an MSc in Primate Conservation at Oxford-Brookes University.

Diani Beach (DB):

DB is a beautiful part of Kenya, situated on the South-East coast that boasts golden sands, turquoise water (which is very warm) and sunshine, sunshine, sunshine. Between all the 5 star hotels and stunning beach bars with chairs literally in the sea is partly fragmented coastal forest. This habitat is home to an amazing array of wildlife and of course primates. The star of the show is the Angolan black and white colobus monkey (colobus) and that is why Colobus Conservation is here.

Colobus Conservation (CC):

In one sentence CC are conserving the colobus monkey on the Kenyan coast.

Established in 1997 the organisation works in partnership with local communities to promote the conservation of the colobus, along with other local primates, and the unique coastal forest habitat on which they depend. Working on simple measures such as tree planting and building Colobridges (See picture below) are ensuring the preservation of the forests and the colobus. To learn more about CC click here.

What am I actually doing?

So my role as a field researcher means I go out into the surrounding areas to watch and record the behaviour and interactions of the different colobus monkey groups. I have to be able to identify the different individuals of the group and then spend time watching each one recording what they are doing. I am also recording how they interact with the other primates and predators in the area as well as where they sleep.

Not much is known about this species of colobus monkey and so continuous research is being undertaken to find out more. This information can then be used to better protect not only the Colobus monkey but the habitat they live in.

First few days in Kenya:

After travelling for 24 hours, with very little sleep I arrived at CC and was shown to where I would be living for the next six months. First thing I noticed is that there are monkeys everywhere, in the trees, on the roof and on the floor. As CC is a safe haven for them they have become very relaxed around humans here and you can get quite close to them.

I met some of the other volunteers and then unpacked and tried to relax. Being the hottest part of the year the temperature is around 33 degrees and the humidity is high; relaxing was not easy. What is nice though is having a chef making our lunch and dinner everyday bar Sunday, and most of the food is Vegan with some meat or fish done separately on occasion. This makes eating at CC very easy for me and most of the food is local African dishes which are lovely. Ugali is a type of mashed potato made from corn flour and water and chapattis is like a very thin pancake. The rest is mainly lots of bean, lentils and vegetables with the odd pizza or burger and chips thrown in.

We are on the beach side and have our own beach access, so within one minute I can be bathing on the glorious beach or swimming in the warm water. Not bad when the heat is just too much.

My work up until now has been mainly training on how to follow and record the colobus monkeys behaviour. Very soon I will be starting my actual study and I will talk about that in future posts.

For now that is it, please ask me any questions you may have and enjoy the pictures below.
