许多研究已经测量了雌性斑胸草雀的交配偏好，Taeniopygia guttata，使用选择室实验，但没有研究集中在如何一致的个别女性在他们的选择和女性同意他们的偏好的程度，虽然这些问题是非常重要的概念。我们进行了大量的配偶选择试验，涉及未操纵的刺激男性，并发现低，但显着的一致性（重复性的时间分配的女性测试两次与同一组男性R = 0.29），和非常低，但显着的女性之间的协议（不同的女性测试与同一组男性：R = 0.11）。虽然低个人的一致性表明，偏好相对较弱或难以衡量，我们发现显着的重复性的个人偏好功能方面的喙的颜色，歌曲率和男性的侵略性时，个别女性进行了两次测试，不同的男性。这意味着一些女性一贯喜欢红喙男性，而其他人更喜欢橙色喙男性，一些喜欢高，其他低的歌曲率，一些喜欢侵略性和其他侵略性较低的男性。在这些男性特征中，只有歌曲率与男性平均吸引力呈正相关。低之间的女性协议似乎并没有导致自愿交配的质量，因为没有重复性的一个单独的女性的偏好有吸引力或没有吸引力的男性。这种分歧可能来自于对遗传相容性的选择，但也可能是由于偏好较弱和男性品质差异不大。(C)2004年，动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Numerous studies have measured the mating preferences of female zebra finches, Taeniopygia guttata, using choice-chamber experiments, but no study has focused on how consistent individual females are in their choices and the extent to which females agree on their preferences, although these questions are of great conceptual importance. We conducted a large number of mate choice trials involving unmanipulated stimulus males, and found low but significant consistency (repeatability of time allocation by a female tested twice with the same set of males R = 0.29), and very low but significant between-female agreement (different females tested with the same set of males: R = 0.11). Although low individual consistency indicates that preferences were relatively weak or hard to measure, we found significant repeatability of individual preference functions with regard to beak colour, song rate and male aggressiveness when individual females were tested twice with different sets of males. This means that some females consistently preferred red-beaked males whereas others preferred orange-beaked males, some preferred high and others low song rates, and some preferred aggressive and others less aggressive males. Of these male traits, only song rate was positively related to average male attractiveness. Low between-female agreement did not seem to result from assortative mating for quality, because there was no repeatability of an individual female's preference for attractive or unattractive males. It is possible that disagreement follows from choice for genetic compatibility, but much of it could also result from weak preferences and little variation in male quality.
