We present data on weight and reproduction from a colony of tufted capuchins monkeys (Cebus apella) over a 12 year period. The data constitute a normative record for this species. Weight at birth averages 210 g, and infants gain weight rapidly. Females typically first conceived just after their fifth birthday, and males were fertile by 4 years, 5 months. Interbirth intervals average 576 days. Eighty-seven percent of live-born infants survived past 6 months. Three of eight live-born infants that died prior to 6 months succumbed from trauma inflicted by cage mates.
我们展示了绒毛蛛猴（Cebus apella）群体在12年期间的体重和繁殖数据。这些数据构成了该物种的标准记录。出生时体重平均为210克，婴儿体重增长迅速。雌性通常在五岁生日后首次受孕，雄性在4岁5个月时具备生育能力。产仔间隔平均为576天。87%的活产婴儿存活至6个月以上。8个活产婴儿中有3个在6个月前死亡，死因是笼舍同伴造成的创伤。
