Few aspects of primate behavior are so intriguing, yet so poorly understood, as the intense care of infants by males. And nowhere among primates is paternal care more extensive than among owl monkeys. Owl monkeys are small, arboreal primates of Central and South America who live in groups with only one reproducing male and one reproducing female. In these monogamous groups, the father is the main provider of infant care, transporting, playing, sharing food and grooming the infant more than the mother. Since 1996, the Owl Monkey Project of Argentina has evaluated hypotheses on the evolution of social monogamy, infant care, and pair bonding in humans and non-human primates. Why do male owl monkeys mate in a monogamous relationship presumably foregoing other reproductive opportunities? Why do they provide so much infant care? The birth of two sets of twins for the first time in 15 years, offers the possibility of further evaluating the hypothesis that males' contribution to infant care reduces the mother's energetic costs. During a 6-month period, this study will characterize the development of the two set of twins and will describe the behavioral interactions between twins and parents, twins and siblings, and parents and older young. Results from this study will be used for comparison with similar data collected over the years in groups with singletons. The study will expand the broad impacts of the Owl Monkey Project. Being the only long-term program on any mammal species in the Argentinean Gran Chaco, the project has multiplying effects on the conservation of this ecosystem and its fauna. It also promotes the development of biological anthropology through the participation over the years of more than 200 students (52% females, 48% males) from the US (100 students), Argentina (120 students) and 14 other countries (30 students).

灵长类动物行为的几个方面是如此有趣，但人们对男性对婴儿的强烈照顾。在灵长类动物中，没有比猫头鹰猴子更广泛的父亲护理。猫头鹰猴子是中美洲和南美洲的小树栖灵长类动物，他们生活在只有一个繁殖男性和一只繁殖女性的团体中。 在这些一夫一妻制的群体中，父亲是婴儿护理，运输，玩耍，分享食物和修饰婴儿的主要提供者，而不是母亲。 自1996年以来，阿根廷的猫头鹰猴子项目评估了关于社会一夫一妻制，婴儿护理和人类和非人类灵长类动物的成对结合的假设。为什么雄性猫头鹰在一夫一妻制的恋爱关系中伴侣可能已经放弃了其他生殖机会？他们为什么提供这么多婴儿护理？ 15年来，两组双胞胎的诞生提供了进一步评估男性对婴儿护理贡献的假设的可能性，从而降低了母亲的精力成本。 在一个6个月的时间里，这项研究将描述两组双胞胎的发展，并描述双胞胎与父母，双胞胎和兄弟姐妹以及父母和年龄较大的年龄较大的行为相互作用。这项研究的结果将用于与多年来与单胎的组中收集的类似数据进行比较。该研究将扩大猫头鹰猴项目的广泛影响。作为阿根廷格兰查科（Gran Chaco）中任何哺乳动物物种的唯一长期计划，该项目对该生态系统及其动物的保护具有多重影响。 它还通过从美国（100名学生），阿根廷（120名学生）和其他14个国家（30名学生）（30名学生）的200多名学生（52％的女性，48％的男性）（52％的女性，48％的男性）（30名学生）（30名学生）参与来促进生物人类学的发展。
