SUMMARY:

Group living presents both advantages and disadvantages for individuals. Among the drawbacks, food competition is one of the major costs of group life, especially in areas with low productivity and high population density, such as forest fragments. To cope with this challenge, individuals adopt different foraging strategies to ensure energy intake while minimizing acquisition costs. Foraging strategies are essential for securing food access and increasing reproductive rates. The adoption of either a tolerant or intolerant stance influences an individual's participation in the available resources as well as their social position within the group. Capuchin monkeys are New World primates with a high neocortical ratio, advanced cognitive abilities, and a complex behavioral repertoire. The blond capuchin (Sapajus flavius) is an endemic species from northeastern Brazil and is currently endangered, with its remaining populations restricted to fragments of the Atlantic Forest and Caatinga. In this study, we will investigate how tolerance during co-feeding experiments among blond capuchins is affected by environmental variables—such as food availability, food type, and fragment productivity—as well as by individual characteristics, such as sex and age. We will also assess whether the type of interaction between individuals influences the amount of food acquired. Observing these animals in the wild is essential for understanding how they behave and cope with competition in their foraging context, particularly in situations of access to critical resources. This is especially important in forest fragments facing continuous reduction and habitat restriction, leading to a decline in available food resources. Understanding how these animals live in groups allows for the development of more effective management and conservation strategies through action plans that consider their social interactions in the wild and how these interactions impact food access and, consequently, reproductive success.
