使用了俄勒冈州Junco（Junco oreganus）和墨西哥Junco（Junco phaeonotus）。这些鸟在孵化后47至90天的年龄范围内通过手术摘除耳蜗而死亡。对聋鸟鸣叫的声谱分析表明，鸣叫的某些方面发展正常，而另一些方面则不正常。俄勒冈州Junco的简单颤音类型的歌曲在这个物种的聋人个体中发展。在野生墨西哥Junco中发现的更复杂的歌曲形式未能在这个物种的聋人鸟类中发展出来。在这两个物种中，震耳欲聋会导致歌曲成分声音的异常。被睾丸激素植入诱导唱歌的失聪雌鸟的歌声与失聪雄鸟的相似。听歌的方式和频率不受耳聋的影响。|| 摘要：M. Konishi
The Oregon Junco (Junco oreganus) and the Mexican Junco (Junco phaeonotus) were used. The birds were deafened by surgical extirpation of the cochlea at ages ranging from 47 to 90 days after hatching. Audiospectrographic analyses of the songs of deaf birds indicated that some aspects of song developed normally, while some other aspects were abnormal. The simple trill type song of the Oregon Junco developed in the deaf individuals of this species. The more complex form of song found in the wild Mexican Junco failed to develop in the deaf birds of this species. In both species deafening caused abnormalities in the component sounds of song. The songs of deaf female birds that were induced to sing by testosterone implantation were similar to those of the deaf males. The manner and frequency with which songs are delivered were not affected by deafness. || ABSTRACT AUTHORS: M. Konishi
