Abstract Species-life history patterns provide insights into the adaptative strategies and importance of social behaviours. The cathemeral activity pattern of Aotus azarae allowed researchers from the Owl Monkey Project of Formosa, Argentina, to witness remarkable life changing events over the complete lifespan of several individuals. Here we summarize the life of Fabian, a male owl monkey we followed from the moment he started searching for a mate until he died. Although still not consistently considered in models of social evolution of mammals, our discovery of a subpopulation of solitary owl monkey floaters forced us to rethink some aspects of their characteristic social organization and mating system. Through the life of Fabian we present some representative examples of the intrasexual competition regulating the social system of the members of this genus during the different stages in the life of individuals, while reporting the first case of extra-pair copulation in wild owl monkeys.
