在以前的研究中，女性偏好和男性展示率或持续时间之间存在正相关关系，但因果关系尚不清楚。雌性斑胸草雀，Taenopygia guttata，被允许在一对雄性之间选择。雌性更喜欢表现得更多的雄性。然而，首选男性显示比非首选男性只有当女性是直接在前面的男性。男性显示的水平增加与女性的接近，但显示努力增加的金额不同个体之间的男性。女性和男性同样有可能开始的遭遇，遭遇持续时间与显示持续时间不相关。因此，观察到的女性偏好和男性展示率之间的相关性是男性和女性行为的结合。男性显示率不同的男性之间的本质，也受到女性接近。
In previous studies a positive correlation has been observed between female preference and male display rate or duration, but the causal relationship remains unclear. Female zebra finches, Taenopygia guttata, were allowed to choose between a pair of males. Females preferred the male that displayed more. However, preferred males displayed more than non-preferred males only when the female was directly in front of the male. The level of male display increased with female proximity but the amount by which display effort increased varied between individual males. Females and males were equally likely to begin an encounter, and encounter duration was not correlated with display duration. The observed correlation between female preference and male display rate was thus a combination of both male and female behaviour. Male display rate varied intrinsically between males, and was also affected by female proximity.
