在自由放养的非人类灵长类动物中，很少有关于雌性配偶选择的研究。为了符合雌性择偶的条件，发情雌性的行为必须能够预测异性恋双性伴侣之间潜在可育交配的发生或比率。在本文中，数据显示了三种符合这一标准的自由放养恒河猴（Macaca mulatta）的行为模式：(1)与雄性的性请求选择性合作（臀部抓住），(2)在雌性被入侵的雄性攻击后恢复接近，(3)接近维持（在两个研究组中的一个）。发情的雌性更倾向于与地位较低的雄性保持接近，但这似乎反映了与不同统治地位的雄性交配所需的策略差异，而不是对地位较低的雄性的偏好。在两个连续的交配季节中，雄性-雌性二联体表现出一致性，在这两个交配季节中，伴侣负责维持亲密关系。雄虫的优势等级与可育雌虫的交配率呈正相关。然而，在一个研究小组中，与发情雌性保持更密切关系的雄性与有生育能力的雌性的交配率更高，这与雄性统治地位的影响无关。
Few studies of female mate choice have been carried out among free-ranging non-human primates. To qualify as female mate choice, behaviour by oestrous females must predict the occurrence or rate of potentially fertile copulations, in comparisons between heterosexual dyads. In this paper, data are presented to show three behaviour patterns that meet this criterion in free-ranging rhesus macaques,Macaca mulatta, at the island colony of Cayo Santiago: (1) selective cooperation with male sexual solicitations (hip-grasps), (2) restoration of proximity following attacks on females by intruding males, and (3) proximity maintenance (in one of two study groups). Oestrous females maintained proximity preferentially to lower ranking males, but this appeared to reflect differences in the tactics necessary to achieve copulations with males of different dominance ranks, rather than preference for lower ranking mates. Male-oestrous female dyads showed consistency over two consecutive mating seasons in which partner was responsible for proximity maintenance. Male dominance rank was positively correlated with copulatory rate with fertile females. However, in one study group, males to whom oestrous females maintained proximity more actively had higher copulatory rates with fertile females, independent of the effects of male dominance rank.
