鸟类的歌唱学习是自相矛盾的。没有辅导，鸣禽不会发展正常的歌曲。然而，尽管没有这种能力，鸟类拥有广泛的预知能力;在机械的意义上，关于它们物种的正常歌声。当给它们选择录音带时，年幼天真的鸣鸟会选择自己物种的声音来模仿。我们磁带辅导白冠麻雀，Zonotrichia leucophrys oriantha，与一组操纵的歌曲，调查是否介绍口哨普遍存在于白冠麻雀的歌曲指导选择性的歌曲学习在这个物种。我们的研究结果证实，这种哨声作为一个线索的歌曲学习，使收购正常拒绝的声音的其他物种，包括隐士画眉，Catharus guttatus，笔记，这有一个声音的质量不同于自然的白冠麻雀短语。我们的研究结果支持的结论是，感觉机制，而不是运动的限制，主要负责在歌曲学习的选择性。(C)2000年，动物行为研究协会。
Song learning in birds is paradoxical. Without tutoring, songbirds do not develop normal songs. Yet despite this inability, birds possess extensive foreknowledge; in a mechanistic sense, about the normal song of their species. When given a choice of tape recordings, young, naive songbirds select sounds of their own species for imitation. We tape-tutored white-crowned sparrows, Zonotrichia leucophrys oriantha, with a set of manipulated songs to investigate whether the introductory whistle universally present in white-crowned sparrow song guides selective song learning in this species. Our results confirm that this whistle serves as a cue for song learning, enabling acquisition of normally rejected sounds of other species, including hermit thrush, Catharus guttatus, notes, which have a sound quality distinct from that of natural white-crowned sparrow phrases. Our results support the conclusion that sensory mechanisms rather than motor constraints are primarily responsible for the selectivity seen in song learning.
