White-headed capuchin
The gestation period is 5 to 6 months. A single young is normally born from each pregnancy. Twins can sometimes be born. Most births happen from December to April. The baby is carried on the mother's back for about 6 weeks.  After 4 to 5 weeks the baby can get off from its mother's back for a short period of time. At 3 months, it can move around by itself. Weaning happens between 6 and 12 months. It is common for Capuchins other than the mother help care for the infant. Males and females engage in this alloparenting.
