At the Detroit Zoo
The Detroit Zoo is one of a handful of zoos in the U.S. to have drills. Males Enwe (born in 2002) and Aiku (born in 2003) arrived in 2008. Aiku is characterized as a high-energy drill while his companion Enwe is serious and calm. The drills spend their days foraging, grooming and playing, just as they would in their native African environment. They share space with chimpanzees and western lowland gorillas at the 4-acre Great Apes of Harambee, located in the African Forest.
The drill is distinguished by its brown fur, hairless black face and long muzzle. It has a ring of white fur that outlines its face. The male drill has a red chin and colorful pink, blue and mauve bottom. The female has a bright red bottom.
