Social ties and bonds are maintained through grooming sessions. Capuchins are highly territorial and mark their trails by urinating on their hands and then rubbing their feet and fur. They use sticks for defense. Capuchins stay within a small but regular range, and within that range they follow regular tracks. Ranges of different troops may overlap.
Capuchins are arboreal, and when they travel together they move in a specific order.
The juvenile males and females go first, then adult males and females, and finally pregnant females. When the infant is young it clings to its mother's front, and as it becomes older it rides on its mother's back during travel. When the infant begins to walk on its own, the mother holds on to the infant's tail in case it slips and falls. If the infant becomes seperated from its mother, another adult will carry it back to its mother. When the group separates in order to find insects, they keep in contact with constant hoarse calls.
