Grooming behaviour in the Red-tailed guenon

The behaviour of the red-tailed guenon (Cercopithecus ascanius) was studied over the course of nine days in the Sabaringo forest surrounding Kichwa Tembo Tented Camp near the Masai Mara National Reserve, Kenya. A focal animal instantaneous sampling method with a one minute interval was used to record the behaviours of the monkeys for approximately 12 hours a day, the day being divided into six shifts á two hours. This method has proven successful in earlier studies of red-tails in this area. The study subjects included both lactating and non-lactating females, juveniles and on some occasions the resident male. The purpose of this study was to examine the grooming behaviour of red-tailed guenons and whether or not the occurrence of grooming varies depending on monkey type (lactating or non-lactating) and time of day.

Habitat preference and foraging behaviour in adult red-tailed monkeys (Cercopithecus ascanius)

The red-tailed monkey (Cercopithecus ascanius) is a small, alert and active animal inhabiting forests with dense vegetation and as such hard to observe in its natural habitat. The principal aim of this study was to scrutinize whether the methods, previously used in a behavioural study of the blue monkey (Cercopithecus mitis) can be applied in studies of the red-tailed monkey?s behaviour as well. Additionally, habitat preference and foraging behaviour of the red-tailed monkey were examined. The study was carried out between the 16th and the 22nd of March 2009 in the Sabaringo forest, located on the western border of the Masai Mara National Reserve.

Antipredator behavior by the red-tailed guenon, Cercopithecus ascanius

This master thesis was conducted in order to investigate the effects of the browsing species Yeheb on animal tissues in Swedish landrace goats and to make a literature review in order to increase the knowledge of the importance of this plant for livestock production in Somalia. The evergreen Yeheb bush is a very important feeding source for grazing and browsing animals in Somalia during the dry period. Yeheb contains cordeauxiaquinone that stains the bones of the animals red/pink, which has been an increasing problem when exporting meat to foreign countries. In an experiment, two goats were fed dry and fresh leaves from the Yeheb bush for one and two months, respectively. The goats did not feed the intended amount of dry leaves, since the supply and palatability was not as high as estimated.

Inventory and evaluation of Nairobi Animal Orphanage : focusing on spotted hyena, serval, Sykes' monkey, vervet monkey and on educational elements

The present BSc thesis is part of a newly established collaboration between the Swedish zoo Skansen and Kenya Wildlife Service (KWS), and constitutes of an inventory of the Nairobi Animal Orphanage (AO). As a refuge for wild animals found orphaned, abandoned or injured throughout Kenya, the AO has grown over the years and reached an unsustainable point where external help is needed for solutions and improvements. The aim of the inventory is to specifically consider the husbandry and enclosures of spotted hyena (Crocuta crocuta), serval (Felis serval), Sykes? monkey (Cercopithecus albogularis) and vervet monkey (Chlorocebus aethiops) and with the aid of facts about the species, estimate how well their biological needs are satisfied. Different educational elements are also reviewed since one of the main purposes of the AO is for education.
