Renowned for their remarkable shyness, mandrills are the most colorful mammals in the world. Relatives of the baboon, mandrills are monkeys that live in the tropics of Western Africa. Males have bright red and blue faces and rumps; their coloring becomes more vivid the more excited they get. A single adult male leads a tribe of up to fifty females and babies. Mandrills are omnivores and spend their days foraging for just about anything they can find—spiders, worms, ants, grasses, shoots, bark, roots, and fruit. At night they sleep safely in the treetops. Baby mandrills are born with their eyes open and quickly form strong bonds with their mothers. They spend hours sitting together and grooming each other’s fur. Daughters stay with their mothers until adulthood, but sons go off on their own as soon as they’re mature. Mandrills have lifespans of thirty years.
