Their body length is about 19.8-25.5 in (50-65 cm). The tail is also as long as the body. Males are larger than the females and weigh more. Even though they are called Blue Monkeys, there is no noticeable blue fur on them. They appear olive or grey normally. They have little hair on their dark faces. But they have a patch of pale fur over their eyebrows which earns them the name of Diademed Monkey. They are diurnal and arboreal primates. Their groups consist of one adult male and several females with their respective young. Mating occurs year-round. The young reach sexual maturity at the age of three. It is estimated that Blue Monkeys live up to 20 years of age but it is not confirmed. They are listed as Least Concern in the IUCN Red List but their population is decreasing due to habitat destruction.

What is a Blue Monkey's habitat?

The Blue Monkey is arboreal and diurnal. The Blue Monkey habitat is the evergreen forest and they are rarely seen off of trees. As most of their diet consists of fruits and leaves, they spend their days foraging for food throughout the forest. They also like to live in places with abundant sources of fresh water and a lot of shade. The Cercopithecus Mitis likes to live in tall trees. They provide them with both food and shelter. But this also means that they are suffering from habitat loss from deforestation.

Who do Blue Monkeys live with?

Blue Monkeys are social animals that live in groups. Females stay in their natal groups but males usually leave the group once they reach adulthood. The size of these groups may range from 10-40 monkeys. There are usually one alpha male monkey and several females and young ones in a group. This means they have a matrilineal society with one male as the head of the troop. Takeovers might happen after a fight and usually, the alpha who lost is ousted from the newly formed troop. The alpha also protects them from other males. Some solitary male monkeys can be seen in the wild. These are usually males who recently left the group in search of another. Sometimes these monkeys also cohabitate and form alliances with other monkey species like the Colobus Monkey and the Red-tailed Monkey. This is most likely for added protection against predators. In a group, interactions are limited and mild. They look for food together. They live in a peaceful social structure and only get agitated when attacked by another group.

How do they reproduce?

The Blue Monkey has a polygynous mating system. Females usually give birth once every two years but can give birth annually if food is available. Males are the larger sex so it is easy to identify them. Females usually present themselves to the male during the mating season. After the mating, females gestate for about five months and then give birth to one offspring during the late summer or rainy season. The offspring are born with fur and open eyes. Their weaning period lasts for about six months. Males of the species have multiple sexual partners while females usually only have one. This happens because in their social groups there is only one adult male and many females and juveniles. Alloparenting has also been seen in this species. Juvenile females take turns taking care of the young monkeys. This allows the young to learn to socialize with other monkeys and learn their ways. But they usually stay away from adult males, it is the females that carry and take care of the young. Both males and females of the species reach sexual maturity at the age of about three years.

What is their conservation status?

The Blue Monkey or the Diademed Monkey is listed as a Least Concern species in the IUCN Red List. This means that their populations are safe in the wild. However, their population trend is decreasing, mostly due to deforestation and habitat destruction.
