Heterosexual affiliation involves behavioral mechanisms that limit bond membership and regulate partners interactions. Among Common Grackles, Quiscalus quiscula, two characteristic activities of partners, following and vocal answering, develop during group activities and promote the individual specificity of pair bonds. Pairs differ substantially in the durations and seasonal timing of the early stages of nesting activities and in the male's fidelity to his mate through incubation. After the relatively abrupt start of intensive nest-building, the seasonal course of a pair's behavior becomes more regular, an indication that this transition in the female's state is critical in pacing the pair's breeding activities. Aggression serves primarily to adjust the spatial relationships of individuals, both between partners and between unpaired birds. males that deserted their mates during incubation had earlier performed precopulatory displays to other males.
异性关系涉及限制群体成员和调节伴侣互动的行为机制。在普通拟八哥（Quiscalus quiscula）中，伴侣的两种典型活动——跟随和声音回应，在群体活动中发展，并促进配对关系的个体特异性。配对在筑巢活动早期阶段的持续时间和季节时间安排上以及雄性在孵化期间对配偶的忠诚度方面存在很大差异。在相对突然地开始密集筑巢之后，一对鸟的行为的季节性进程变得更加规律，这表明雌性状态的这种转变对于安排这对鸟的繁殖活动至关重要。攻击行为主要用于调整个体之间的空间关系，包括伴侣之间以及未配对鸟类之间的关系。在孵化期间抛弃配偶的雄性之前曾向其他雄性进行过交配前展示。
