Few aspects of human and non-human primate behavior are so intriguing as the intense care of infants by fathers, and nowhere among primates is paternal care more extensive than among owl monkeys. Owl monkeys are small, arboreal neotropical primates who live in monogamous groups with only one reproducing male and one reproducing female. The father is the main provider of infant care, transporting, sharing food and grooming the infant more than the mother; paternal investment is exceptionally strong and apparent in this species. Research focused on these primates should inform our understanding of the functional and evolutionary significance of this distinctive reproductive system.Since 1996, the Owl Monkey Project of Argentina has evaluated hypotheses to explain the evolution of social monogamy and infant care in primates. In this study, a team of investigators and students from the US and Argentina will evaluate the hypothesis that the functional significance of paternal care in owl monkeys relates to the bioenergetic benefits that the parenting couple accrues from the father's assistance. Taking a novel approach that combines research on both captive and wild owl monkeys, the team will gather data on foraging and activity patterns, body mass changes, energy intake, and hormones. The relevance of the study, which has the potential to transform how energetics are measured in the field, lies in contributing to the understanding of the role of males in societies that are characterized by a strong bond between partners and shared parental duties. The study will expand the broad impacts of the Owl Monkey Project. As the only long-term research 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 young scientists and the discipline of biological anthropology through the participation over the years of more than 270 students (55% females, 45% males) from the US, Argentina and 14 other countries; student training and involvement in the research will further augment this strong record.

人类和非人类灵长类动物的行为中，很少有哪一个方面像父亲对婴儿的悉心照料那样令人感兴趣，而在灵长类动物中，没有哪一种动物的父亲照料比猫头鹰猴更为广泛。猫头鹰猴是一种小型的树栖新热带灵长类动物，它们生活在一夫一妻制的群体中，只有一个繁殖雄性和一个繁殖雌性。父亲是照顾婴儿的主要提供者，运输，分享食物和梳理婴儿比母亲更多;父亲的投资在这个物种中异常强大和明显。对这些灵长类动物的研究应该为我们了解这种独特的生殖系统的功能和进化意义提供信息。自1996年以来，阿根廷的猫头鹰猴项目评估了解释灵长类动物社会一夫一妻制和婴儿护理进化的假设。在这项研究中，来自美国和阿根廷的一组调查人员和学生将评估一个假设，即猫头鹰猴父亲照顾的功能意义与父母从父亲的帮助中获得的生物能量益处有关。研究小组采用了一种新的方法，将对圈养和野生猫头鹰猴的研究结合起来，收集有关觅食和活动模式、体重变化、能量摄入和激素的数据。这项研究有可能改变在实地测量能量的方式，其相关性在于有助于理解男性在社会中的作用，这种社会的特点是伴侣之间的牢固联系和共同的父母责任。这项研究将扩大猫头鹰猴子项目的广泛影响。作为阿根廷大查科地区唯一的哺乳动物物种长期研究项目，该项目对保护这一生态系统及其动物群具有多重影响。 它还通过多年来来自美国，阿根廷和其他14个国家的270多名学生（55%女性，45%男性）的参与促进了年轻科学家和生物人类学学科的发展;学生培训和参与研究将进一步增强这一强劲的记录。
