鸟类使用不同的发声来标记它们的领地和吸引配偶。有三类鸟类(鸣禽、鹦鹉和蜂鸟)通过模仿来学习发声。在这样的声乐学习者的大脑中，有一个被称为歌曲系统的神经网络，专门用于声乐学习和产生。相比之下，鸡和鸽子等鸟类没有这样的神经网络，只能发出先天的声音。由于每种鸟类都表现出不同的、遗传的与其形态相关的发声学习能力，鸟类发声系统是研究功能神经回路进化的一个很好的模型。然而，从进化发育生物学(Evo-Devo)的角度对鸟类发声的研究还很少。在本综述中，我们总结了鸣禽研究的结果和我们最近使用Evo-Devo方法来理解鸟类发声系统进化的工作。

Birds use various vocalizations to mark their territory and attract mates. Three groups of birds (songbirds, parrots, and hummingbirds) learn their vocalizations through imitation. In the brain of such vocal learners, there is a neural network called the song system specialized for vocal learning and production. In contrast, birds such as chickens and pigeons do not have such a neural network and can only produce innate sounds. Since each avian species shows distinct, genetically inherited vocal learning abilities that are related to its morphology, the avian vocal system is a good model for studying the evolution of functional neural circuits. Nevertheless, studies on avian vocalization from an evolutionary developmental‐biological (Evo‐Devo) perspective are scant. In the present review, we summarize the results of songbird studies and our recent work that used the Evo‐Devo approach to understand the evolution of the avian vocal system.
