Phylum —chordata

Order — primates
Family — cercopithecidae

Genus – сercocebus

Appearance

These are large quadrupedal monkeys that have cheek pouches to store food during foraging. Golden-bellied mangabeys have an orange fur on their front side and are usually brown, black, white, or gray on the back side. These primates have very long tails that are even longer than their bodies and provide good balance when animals move through the tree canopy.

Weight 4-14 kg, length 40-80 см.

Habitat

Golden-bellied mangabeys are found south of the Congo River in the Democratic Republic of the Congo.

Behavior

Golden-bellied mangabeys are social creatures. They live and travel in groups of 8 to 30 members. They forage for their food both in trees and on the ground. Groups can travel up to 1000 square meters per day. Golden-bellied mangabeys are crepuscular and are most active before sunrise because at this time it is easier to find food. Mangabeys can be very noisy and communicate with each other primeraly with the help of the sound. These animals have a special throat sac that gives them a booming voice. This sac is larger in the adult males and they are able to make shrieking alarm calls which alert others to danger. A dominant male will also bark, produce twitters, and grunt in order to let other mangabey groups in the area know where his group is so they don't come close. Adult females often join males with a loud chorus. Adult males also make a so-called whoop-gobble sound. This sound gets the attention of other mangabeys in the area and tells everyone who and where he is. This unique call can be heard as far as up to 1 kilometer.

Diet

Golden-bellied mangabeys are omnivores. They feed on insects and spiders, fruits, leaves, nuts, and seeds. These animals may also feed on nectar sometimes.

Reproduction

Golden-bellied mangabeys are polygynandrous (promiscuous) which means that both males and females have numerous mates. The breeding season takes occurs from March to August. Females give birth to a single infant after the gestation period that lasts around 160-180 days. Infants are born alrticial (naked with their eyes closed) and weigh 500-600 g. The young are nursed and protected until 8 to 9 months of the age and become fully independent when they are 4-5 years old. Males in this species become reproductively mature at 5-7 years of age, while females reach reproductive maturity at around 4-5 years of age.

The recorded lifespan for captive Golden-bellied mangabeys is between 20 to 35 years, with an average lifespan of 30 years.

In captivity

Mangobei are well tamed in captivity. Minimum enclosure size for one gibbon is 2*2*2 meters. The door should be large, with a sliding tray at the bottom. In the aviary, you need to install thick branches of fruit trees, a rope, and a ladder (you can buy it in a children's sports store).

Bowls should be thick and with high sides, preferably metal.

When monkeys are getting used to diapers the kipper should use the smallest children's ones, for particularly small monkeys are suitable "for premature babies".

Diet:

- fruits: apples, pears, bananas, kiwi, grapes, mango, papaya, oranges, tangerines (a little);

- vegetables: cucumbers, carrots, asparagus, broccoli, lettuce, spinach, tomatoes, cabbage, boiled potatoes;

- meat: chicken, turkey-cooked;

– eggs-quail, chicken-boiled;

- vitamin supplement: Vitamin D3, Vitamins B12 for animals.

Monkeys are very intelligent animals, and like all developed animals, they need to play often and a lot. The keeper may use toys, it is better to buy them in a store for children.
