Biology
An influential male leads a multi-male multi-female team of 20-30 people and is the father of many young people. This group can join others by creating a supergroup of over 100 people. They are semi-seasonal during the season and often rub on trees in their chests to identify their territory. They are half-ground, originally raised to the ground, but climb up trees to sleep at night. Women give birth to a single child; A twin was recorded at the Nigerian Drill Rehab and Breeding Center.
The average length of captivity is 28 years
The diet mainly consumes a lot of fruits but is eaten by plants, roots, eggs, insects and small mammals.
Distribution and Status
The Mandrillus drills are found only in the cross river state of Nigeria, in southwestern Cameroon (south of the Sanaga River) and in the rainwater habitat on the island of Bioko, part of Equatorial Guinea. Their entire world range is less than 40,000 kilometers.
Mandrillus drills are among Africa’s most endangered mammals and are listed by the IUCN as the highest conservation priority of all African primates. The number of drills in all known habitat areas has been declining as a result of decades of illegal commercial hunting, habitat destruction, and human development.
About 1 in 5 Mandrillus drills may be in the wild, with the highest population estimate being only 5.7. A total of 414 drills recovered from illegal captures are in semi-confinement at the Drill Rehabilitation and Breeding Center in Nigeria, with high success rates for breeding and about 4 in other zoos internationally.
