鸟鸣是一种复杂的、习得的行为。麻雀的发声学习涉及几个不同的过程，这些过程在第一年的生命过程中以不同的时间模式发生。歌曲是在生命的前3个月内的一段敏感时期不经过练习而获得的，直到7或8个月大时才开始排练获得的歌曲。歌曲获取和制作之间的保存期的作用尚不清楚。我们开始通过给100天龄的鸟类注射睾酮来研究它的意义，睾丸激素已知可以刺激成年鸟的鸣叫产生，在鸣叫完成后，大约5个月前正常鸣叫开始。大多数接受睾丸激素处理的鸟类产生的异常歌声类似于在声学隔离中饲养的雄性鸟类的歌声，这表明，在麻雀的存储阶段发生的事件在发声学习中发挥着重要作用。©1995 John Wiley&Sons，Inc.
Bird song is a complex, learned behavior. Vocal learning in sparrows involves several different processes that occur in a distinct temporal pattern over the course of the first year of life. Songs are acquired without practice during a sensitive period within the first 3 months of life and rehearsal of the acquired song does not begin until 7 or 8 months of age. The function of the storage period between song acquisition and production is not known. We set out to investigate its significance by administering testosterone, known to stimulate production of adult song, to birds at 100 days of age after song acquisition was completed but some 5 months prior to normal song onset. Most testosterone‐treated birds produced abnormal songs resembling those of males raised in acoustic isolation suggesting that, in sparrows, events occurring during the storage phase play a significant role in vocal learning. © 1995 John Wiley & Sons, Inc.
