The Mandrill becomes mature at about 3 ½ years of age. The females will initiate mating if she is interested in him. It takes about 5 months from conception for the young to be born. There is no set mating season for these Monkeys. The mothers are very excited to have the young arrive. They take very good care of them and won’t mate again until the young they have to care for are mature. If a baby should die then they will mate again in the hopes of being able to replace it.


In many areas the Mandrill is seen as a pest because they will destroy crops and living areas of the villagers. These animals are heavily hunted in order to provide food for many of the villagers.
