鸣唱在鸣禽的择偶过程中起着重要作用。男性广告歌曲是文化传播，导致个人或人口特定的歌曲变体。越来越多的证据表明，女性对歌曲的偏好受到她们年轻时所经历的歌曲变体的影响，但对获得过程本身的性质和时间仍然知之甚少。歌曲收购（以及性印记）已被研究更详细的斑胸草雀（Taeniopygia guttata）比任何其他鸣禽物种，使其及时审查的后果，早期暴露在这个物种的女性歌曲感知。目前的文献提供了大量的证据，不仅偏好学习，但也依赖于确定性的知觉微调。对歌曲偏好学习的敏感性在发展过程中会发生变化。偏好学习似乎不会发生在25日龄之前（因此与男性获得歌曲的时间过程平行），但目前潜在的终点不太明显。然而，迄今为止的研究都集中在学习的结果，而不是过程，因此没有旨在划定一个敏感的阶段。早期获得的歌曲偏好似乎非常稳定，无论额外的经验，这表明一个自我终止的过程，如以前发现的性印记。我们对歌曲偏好学习过程的机制的理解仍然存在明显的差距，但这些似乎值得解决，因为择偶的结果可能会因学习的时间和学习的对象而有很大的不同。
Song plays an important role in mate choice in oscine songbirds. Male advertising song is culturally transmitted resulting in individual- or population-specific song variants. Evidence is accumulating that female song preferences are influenced by those song variants they experienced when young, but the nature and timing of the acquisition process itself is still poorly understood. Song acquisition (as well as sexual imprinting) has been studied in more detail in zebra finches (Taeniopygia guttata) than in any other songbird species, making it timely to review the consequences of early exposure on female song perception in this species. The current literature provides substantial evidence not only for preference learning but also for exposure-dependent perceptual fine-tuning. Sensitivity for song preference learning changes over the course of development. Preference learning does not seem to occur earlier than 25 days of age (hence paralleling the time course for song acquisition in males), but a potential endpoint is currently less obvious. However, studies so far have focussed on the outcome rather than the process of learning, and thus have not aimed at delineating a sensitive phase. Early acquired song preferences seem highly stable regardless of additional experience, which suggests a self-terminating process as previously found for sexual imprinting. There are still obvious gaps in our understanding of the mechanisms underlying the process of song preference learning, but these seem worthwhile addressing, as the consequences for mate choice might differ dramatically depending on when and from whom learning takes place.
