鸟鸣是研究获得性发声通讯信号的神经生物学、发育和功能的模型系统。鸟类歌唱学习的研究一直被一种指导性的学习模式--感觉运动模式所主导。发育可塑性被认为是基于将新材料融入歌曲曲目中。实验证据现在表明，另一种形式的可塑性与感觉运动学习和谐地运作，基于选择的原则，而不是指导。歌曲方言是声乐学习的常见结果，可以通过过度生产之前记忆的歌曲和选择性地减少那些与男性互动的方言不匹配的歌曲来实现。这些不同的学习过程对于研究歌曲产生和感知的神经基础，以及努力解释歌曲中的地理变异模式具有重要意义。
Bird song is a model system for study of the neurobiology, development, and functions of learned vocal communication signals. Research on avian song learning has been dominated by an instructive model of learning-the sensorimotor model. Developmental plasticity is assumed to be based on the incorporation of novel material into the song repertoire. Experimental evidence now indicates an alternative form of plasticity operating in harmony with sensorimotor learning, based on principles of selection, rather than instruction. Song dialects, a common consequence of vocal learning, can be achieved by overproduction of previously memorized songs and selective attrition of those that fail to match the dialect of interacting males. These distinct processes of learning have important implications for study of the neural substrates underlying song production and perception and for efforts to interpret patterns of geographic variation in song.
