The red-tailed monkey is a West and Central African species that reaches the eastern edge of its range on the shores of Lake Tanganyika. It is quick and nervous, and chimpanzees occasionally hunt it, so a troop will scatter when the chimps call.
Gombe is famous among primatologists for the red-tailed and blue monkeys that have hybridised in its valleys. For visitors it simply means more monkeys to watch on the walk to the chimpanzees.
