Drill

Mammals

The drill (Mandrillus leucophaeus) is a primate of the family Cercopithecidae, related to the baboons and even more closely to the mandrill. It occurs in Nigeria, Cameroon and Equatorial Guinea, in fragmented populations that include lowland coastal forest on Bioko Island, other forests, savanna, mountain peaks and inland cliffs. The species is semi-terrestrial. Males average about 32 kilograms and 82 centimetres in length, while females average about 12 kilograms and 66 centimetres. The drill is an opportunistic omnivore whose main foods are seeds, plants, mushrooms, fruit and some invertebrates, and wild animals live about 20 years. About 4,000 individuals remain in the wild. It is listed as endangered and is threatened by hunting, the pet trade and loss of forest to agriculture and plantations, and it is protected in areas such as Cross River National Park.
