Intergroup interactions in nonhuman primates can vary greatly from affiliative to agonistic. While many researchers have focused on factors that lead to aggressive intergroup encounters (IGEs), few have investigated those that lead to more tolerant outcomes. Here, we examine how fruit productivity, mating opportunities, group composition, and location of encounter affect IGEs in wild woolly monkeys –\u00a0 a taxon noted for having male philopatry, flexible grouping dynamics, high degrees of home range overlap, and IGEs that range from peaceful and tolerant to more hostile. Behavioral and spatial data were collected from four groups of habituated woolly monkeys at the Tiputini Biodiversity Station from the years of 2014 and 2015. IGEs were recorded opportunistically any time an individual from another social group was visually or acoustically observed to be within 100 m of an observer\u2019s focal subgroup. During IGEs, observers recorded the identities and\/or age-sex class of as many members from the other social group as possible, as well as the location of the encounter and the general activity of both groups prior to, during, and after the IGE. We used binomial generalized linear mixed models to assess the impact of fruit availability, mating opportunities (number of copulating females\/month), group composition, and distance from center of home range on IGE outcome (tolerant or not tolerant). We recorded 102 IGEs throughout our study period with nearly 60% of encounters classified as tolerant. The average duration of IGEs was 122 minutes, with IGEs ranging from several minutes to multiple days. Of the factors tested, only mating opportunity had a significant impact on IGE outcome, with IGEs significantly less likely to be tolerant as the number of females observed copulating increased (\u03b2 = -0.19265, p < 0.0106, and model from null (p < 0.01269)).<\/p>\n\n\n\n
