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很少有像父亲对婴儿的密集照顾这样耐人寻味的，而在灵长类动物中，父亲的照顾也没有像猫头鹰猴子那样广泛。猫头鹰猴是一种小型的树栖新热带灵长类动物，生活在一夫一妻制的群体中，只有一只繁殖的雄性和一只繁殖的雌性。父亲是照顾婴儿的主要提供者，比母亲更多地运送、分享食物和给婴儿梳理毛发；在这个物种中，父亲的投资格外强大和明显。专注于这些灵长类动物的研究应该有助于我们理解这种独特的生殖系统的功能和进化意义。自1996年以来，阿根廷的猫头鹰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说。在这项研究中，一组来自美国和阿根廷的研究人员和学生将评估这一假设，即猫头鹰猴子父亲照顾的功能意义与养育夫妇从父亲的帮助中获得的生物能量好处有关。采用一种新的方法，结合对圈养和野生猫头鹰猴子的研究，该团队将收集关于觅食和活动模式、身体质量变化、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以伴侣之间牢固的纽带和分担父母责任为特征的社会中的作用。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一一项针对哺乳动物物种的长期研究计划，该项目对这一生态系统及其动物的保护产生了成倍的影响。它还通过来自美国、阿根廷和其他14个国家的270多名学生(55%是女性，45%是男性)多年来的参与，促进了青年科学家的发展和生物人类学的学科；学生培训和参与研究将进一步增强这一强劲记录。
