Habit:
Grivet is a semi-terrestrial, savanna monkey that lives in groups ranging from 6 to 20 individuals, with a hierarchical order among several males and females. They are active during the day, especially in the morning and early evening, and rest in the shade during the heat of the day. At night, the group sleeps together in a large tree to avoid predators. Their diet is mainly vegetarian, consisting of fruits, vegetables, grass seeds, bulbs, and flowers. However, they also consume insects, eggs, and young birds. Urban populations are well adapted to city life, scavenging for human food and opportunistically stealing when the chance arises.
