鸟类并不总是随机发声，而是可能以避免与其他鸟类的歌曲重叠的方式划分声音空间。实际上，许多同时活跃的歌手可以以最小的重叠精细地整合歌曲，从而实现高度的沟通效率。我们通过在加利福尼亚州火山附近的主要研究地点的几个录音来描述这种现象。用于概念化和研究此类去同步系统的研究最多的模型来自计算机科学中的调度算法，其中互联网协议涉及广泛广播的信息包；它们之间的任何冲突都会破坏冲突数据包，因此需要重新发送它们。我们模拟了其中一些可能适合鸟类群落声音空间的方法。这些不同步的某些功能取决于所使用的算法的具体情况。
Birds do not always vocalize at random, but may rather divide up soundspace in such a manner that they avoid overlap with the songs of other bird species. In effect, a high degree of communication efficiency can be achieved by many simultaneously active vocalists that finely integrate songs with minimal overlap. We describe this phenomenon from several recordings at our principal study location, near Volcano, California. The most-studied models for conceptualizing and studying such de-synchronized systems come from scheduling algorithms in computer science, where internet protocols involve packets of information that are broadcast widely; any collisions between them will corrupt the colliding packets so that they need to be resent. We have simulated some of these methods that might be appropriate for the soundspace of bird communities. Some features of these de-synchronized depend on specifics of the algorithms used.
