一些鸣禽的发声器官，即空肠，被假设为包含两个可以独立操作的声源。鸣禽(Oscines)的空洞是一个两部分的结构1，2其两侧潜在地能够共同或独立地产生声音3-9。一些物种的发声是侧化的，因此一侧产生了大部分的Song9-11。我现在已经直接测量了猫鸟和鸣禽在歌唱时左右两侧空洞的声音输出和运动动力学。在这些鸟类中，声音可以由空洞的任何一侧单独发出，也可以通过两侧共同作用或从一侧切换到另一侧来发出。当音符的两侧同时构成一个音符或音节时，它们可能发出相同的声音，也可能发出不同的声音。给定的音节类型是由相似的运动模式在每次产生时产生的。
THE vocal organ, the syrinx, of some songbirds has been hypothesized to contain two sound sources that can be operated independently. The syrinx of songbirds (Oscines) is a bipartite structure1,2whose two sides are potentially capable of acting either together or independently to produce sound3–9. Sound production is lateralized in some species such that one side produces most of the song9–11. I have now directly measured the acoustic output and motor dynamics of the left and right sides of the syrinx during song in catbirds and thrashers. In these birds, sound may be produced by either side of the syrinx alone, by both sides acting together, or by switching from side to side. When both sides of the syrinx contribute simultaneously to a note or syllable, both may generate the same sound or each side may produce a different sound. A given syllable type is generated by a similar motor pattern each time it is produced.
