This baboon is no buffoon: Once revered by Ancient Egyptians as representatives of the Egyptian god of learning, hamadryas baboons are also referred to as Sacred Baboons. These hardy Old World monkeys display complex social behaviors, and can live in troops of several hundred individuals. Though currently extinct in Egypt, these monkeys can be found in large populations in Ethiopia, Somalia, Saudi Arabia, and Yemen. In fact, no other species of baboon resides as far north as hamadryas baboons. The remarkable silver manes and pink faces of adult males add to the unique nature of these intelligent primates.Hamadryas baboons are large-bodied monkeys with a strong build and a dog-like muzzle. Both males and females have brown or light gray fur. While the females of this species have hairless black and brown faces, the male hamadryas baboon has a distinctive mantle (mane) of long silvery hair and a bright pink face and backside. These baboons sport a relatively short, tufted tail that is not prehensile.
