The dominant female can monopolize the male if she wants to, but she usually does so in wild groups only when she has no alternative related female partners available. The male's interactions with his main partner are similar to those that characterize close female-female relationships. Here, we explore whether dominance rank and kinship predict female social bonds in a wild population of geladas ( Theropithecus gelada ), a species that differs from other cercopithecines in that the individuals have 1) an unusual modular social system, 2) low food competition, and 3) extraordinarily high levels of social tolerance.
