Blue monkey pictures and facts

The Blue Monkey (Cercopithecus mitis) also known as the Diademed Monkey is a member of the guenon genus. It is native to East and Central Africa, Ranging from the northern part of the Congo River Basin to the east of the Great Rift Valley and to the south of northern Zambia and Angola.

Although, called 'Blue Monkey', the 'blue' is not really noticeable. The small hair on its face sometimes gives the impression of blue color and hence its name. Apart from its face, its coat is grey or olive in color and there is a yellowish patch on its forehead called the 'Diadem' from which the name Diademed Monkey has been derived. Its legs, feet, and cap are black and the mantle is brown, grey, or olive depending on the species. The Blue Monkey has pouch in its cheeks to carry food while foraging. An average mature blue monkey is 19.68 - 25.59 inches (50 - 65 cm) long and the length of its tail is equal to the length of the rest of its body. The female blue monkey weighs about 8.81 lbs (over 4 kg) and the weight of the male is about 17.63 lbs (8 kg).

The Blue Monkey is mainly found in bamboo forests, evergreen forests, and in thick forest canopies. It very rarely comes to the ground. In order to meet its need of water, it depends on the humid and shady areas where water is found in plenty. Leaves and fruits are its main food but it sometimes eats slow moving invertebrates as well. Tall trees are its most preferred home where it gets both the required shelter and food. Since the green cover is vanishing rapidly, it is also suffering the loss of its natural habitat like other animals. At places where the pine trees are replacing the natural green cover, the blue monkey is considered a threat as it may strip the bark in search of food and moisture. Humans also hunt it for its bushmeat.

The Blue Monkey males are larger than the females. Females generally give birth once in two years during the start of warm, moist rainy seasons. The gestation period lasts for about 5 months. Infants take birth with their eyes open and fur all over their body. The Blue Monkey roosts in groups of 10-40 individuals with only one adult male.

This species believes in the unmale-per-group tendency and the male receives the copulations from the females in the group. The male guards the group from any predators and females also join him in this activity. The stronger male sometimes ousts the male thereby overtaking the troop. In order to protect themselves from predators, these Blue Monkeys get mixed with other species of monkeys. No competition is seen between the two groups since they forage in diverse locations.

This species has a variety of habitats but it always stays close to water. Somalia, Angola, South Africa, Zambia, Zimbabwe, Uganda, Tanzania, Sudan, Malawi, Kenya Burundi, Ethiopia, Zaire, Rwanda, and Mozambique are countries where the Blue Monkey is found in abundance.
