These animals mate polygynously, with the dominant male in the troop copulating with all of the receptive females.
Mating System: polygynous
Weeping capuchins are polygamous. There is one dominant male who is responsible for mating with all receptive females in the troop.
Males reach reproductive maturity at 7 years and females are able to bare young in their fourth year (Eisenberg and Redford, 1989). Mature females produce offspring every 19 months on average, although it is not uncommon for females to give birth in successive years. (DiBitella and Janson, 2001). Females give birth to 1 young after a gestation period of 160 days. The infant weighs approximately 200 to 500 g and is able to cling to its mother's hair only moments after being born (Nowak, 1999).
Breeding season: Breeding season: Oct. -Feb. during peak food availability
Range gestation period: 145 to 170 days.
Average gestation period: 160 days.
Range weaning age: 1.5 to 4 months.
Average weaning age: 2.35 months.
Average age at sexual or reproductive maturity (female): 4-6 months.
Average age at sexual or reproductive maturity (male): 7-9 months.
Key Reproductive Features: iteroparous ; year-round breeding ; gonochoric/gonochoristic/dioecious (sexes separate); viviparous
Average number of offspring: 1.
Average age at sexual or reproductive maturity (female)

Female capuchins are the primary care givers. The male may invest some time in foraging for the female but invests little or nothing in parental care (Nowak, 1999).
Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female)
