The Bolivian squirrel monkey (Saimiri boliviensis boliviensis) is a seasonal breeder. Male squirrel monkeys show distinct morphological and behavioral changes prior to and during the breeding season. A "fatting syndrome" includes increased body weight, increased levels of androgens, and in the Bolivian subspecies, an increasingly active role in the social organization of the group. In this study, the behavior of ten adult male Bolivian squirrel monkeys was analyzed over a 6-month period prior to, during, and after the breeding season. Each was housed as the only adult male in a breeding unit with six to ten adult females and one juvenile male. Employing a principle components method, 11 behavioral clusters were generated from 27 responses. Their activity clusters were identified as follows: sexual activity that showed a peak around the time of peak conceptions; excitatory activity that was initially high but decreased throughout the breeding season; and maintenance activity that did not change across the breeding season. The changing social behavior of the male squirrel monkey parallels physiological changes and is correlated with changing androgen levels.
玻利维亚松鼠猴（Saimiri boliviensis boliviensis）是季节性繁殖动物。雄性松鼠猴在繁殖季节之前和期间会表现出明显的形态和行为变化。一种“增肥综合征”包括体重增加、雄激素水平升高，在玻利维亚亚种中，还包括在群体社会组织中发挥越来越积极的作用。在本研究中，对10只成年雄性玻利维亚松鼠猴在繁殖季节之前、期间和之后的6个月内的行为进行了分析。每只猴子作为唯一的成年雄性被安置在一个繁殖单元中，该单元中有6至10只成年雌性和1只幼年雄性。采用主成分分析法，从27种反应中生成了11个行为簇。它们的活动簇被确定如下：性活动在受孕高峰期左右达到峰值；兴奋性活动最初较高，但在整个繁殖季节逐渐下降；维持性活动在整个繁殖季节没有变化。雄性松鼠猴不断变化的社会行为与生理变化平行，并且与雄激素水平的变化相关。
