According to National Geographic, Drills are shy creatures that live in one small and remote area of Africa. Their faces aren’t as colourful as another species in their genus the Mandrill. Yet Drills still possess a dramatic appearance with pitch-black faces surrounded with a white fringe. Males have fatty cheek pads and a splash of red under their lower lips gives them the appearance of having broken into a makeup cabinet.

Drills live in the coastal lowland forests and semi-montane forests. In the 1930s, Sanderson (1937) collected Drills in mixed grassland-gallery forest of Cameroon’s Bamenda Highlands but these forests are now largely eliminated. Within the core habitat of the Drill, vast tracts of rainforest have been converted to palm oil, rubber, tea and banana plantations in the last 80 years from Mount Cameroon east to Douala.

The species is threatened by habitat loss, fragmentation and hunting. Habitat loss results from forest clearance on a small but extensive scale for farms, particularly in Nigeria, for large-scale plantations, particularly in Cameroon where multiple oil palm plantation projects are underway or proposed (Morgan et al. 2013), and from commercial logging in Cameroon where several important forests peripheral to Korup are now designated as concessions (C. Astaras pers. comm. 2016).

Drills are threatened by deforestation, particularly in Cameroon where multiple oil palm plantation projects are already underway or proposed (Morgan et al. 2013).

Hi, I’m Palm Oil Detective’s Editor in Chief. Palm Oil Detectives is partly a consumer website about palm oil in products and partly an online community for writers, scientists, conservationists, artists and musicians to showcase their work and express their love for endangered species. I have a strong voice for creatures great and small threatened by deforestation. With our collective power we can shift the greed of the retail and industrial agriculture sectors and through strong campaigning we can stop them cutting down forests. Be bold! Be courageous! Join the #Boycott4Wildlife and stand up for the animals with your supermarket choices
