Capuchin Monkeys live in a group of 10-30 members. Generally, the group will be dominated by a single male, who has the primary right to mate with the females in the group. However, one of the white faced capuchin monkey facts is that in the group of this species there will be an alpha male and an alpha female. The females in the group mate preferentially with the alpha male, but the other monkeys have a chance when the alpha male is not present. Parenting is left to the females, the infants are nurtured and cared by the mothers for first few months.
