Mate guarding and coordinated behaviors between partners are important for the maintenance of monogamous pair bonds. To study the effects of a perceived unfamiliar social intruder on females' behavior, we used coppery titi monkeys (Plecturocebus cupreus ). We examined the effects of male aggressive temperament on females' behavior and the effects of each behavior performed by the male on the same female behavior. Using a mirror, we simulated a social intruder in the home territory and scored behaviors using an established ethogram. Based on our analysis of self‐directed behaviors, females do not recognize themselves in the mirror. We then used general linear mixed models to predict percent change in females' behaviors as a function of (a) males' temperament, (b) males' behavior, and (c) an interaction between males' temperament and behavior. Male temperament did not significantly predict female behavior for any of our best fitting models. For percent change in female lip‐smacking, male lip‐smacking significantly predicted female lip‐smacking (β  = 0.74, SE  = 0.22, t  = 3.39; p  = .004). There was a positive correlation between male and female agonistic behaviors such as back‐arching/tail‐lashing (β  = 0.51, SE  = 0.23, t  = 2.22; p  = .04) and for anxiety‐related behaviors such as leaving the partner (β  = 0.50, SE  = 0.19, t  = 2.68; p  = .015), locomotion duration (β  = 0.19, SE  = 0.06, t  = 2.98; p  = .02), and locomotion frequency (β  = 0.71, SE  = 0.14, t  = 5.17; p  < .001). These findings on coordination of pair‐mate behaviors may explain how titi monkeys display pair bond strength and ensure their reproductive success.

铜山雀猴（Plecturocebus cupreus）对在响应模拟入侵者时显示协调的行为。

伴侣之间的伴侣保护和协调行为对于维持一夫一妻制的成对债券非常重要。为了研究感知到的陌生社交入侵者对女性行为的影响，我们使用了铜制山雀猴（Plecturocebus cupreus）。我们研究了男性攻击性气质对女性行为的影响，以及男性对同一女性行为的每种行为的影响。使用镜子，我们模拟了本国领土内的一个社会入侵者，并使用已建立的人种图对行为进行了评分。根据我们对自我指导的行为的分析，女性无法在镜子里认出自己。然后，我们使用一般线性混合模型来预测女性行为的百分比变化，该变化是（a）男性气质，（b）男性行为以及（c）男性气质与行为之间的相互作用的函数。在我们的最佳拟合模型中，男性气质并未显着预测女性行为。对于女性嘴唇打滑的百分比变化，SE  = 0.22，t  = 3.39；p  = .004）。男性和女性的激动行为之间存在正相关，例如后弓/尾巴绑扎（β  = 0.51，SE  = 0.23，t  = 2.22; p  = .04），而与焦虑相关的行为例如离开伴侣（β  = 0.50，SE  = 0.19，t  = 2.68; p  = .015），运动持续时间（β  = 0.19，SE  = 0.06，t  = 2.98; p  = .02），运动频率（β  = 0.71，SE  = 0.14） ，t  = 5.17；p  <.001）。这些关于配对行为协调的发现可能解释了titi猴子如何表现出配对键强度并确保其繁殖成功。
