先前对鸟类学习鸣叫的研究表明，在鸣叫组织中存在着物种通用的模式：在一个物种内没有变化的鸣叫中有明显的集群。在这里，作者结合联合收割机的计算方法比较歌曲与统计方法评估集群结构，以调查这个问题，在一个更定量的方式。作者首先分析了歌曲的音韵，然后在种群水平上研究歌曲的句法，在3个物种有非常不同的歌曲结构：苍头燕雀（Fringilla coelebs），斑胸草雀（Taenopygia guttata），和沼泽麻雀（Melospiza georgiana）。作者使用动态时间规整算法来比较歌曲元素，这与人类观察者的判断非常吻合。聚类趋势和验证统计表明，广泛的语音类别存在于所有3个物种，但这些类别解释不超过一半的整体语音变异。作者开发了一种新的统计方法来评估句法结构，这表明元素转换不是随机分布的。在最明显的情况下，在苍头燕雀，这可以解释为音节被链接到歌曲中的某些位置。这些结果表明，歌曲组织的措施，可以适用于跨物种，提高比较研究的潜力。
Previous studies of learned bird song have suggested the existence of species-universal patterns in song organization: clear clusters in produced songs that do not vary within a species. Here the authors combine a computational method of comparing songs with statistical methods of assessing cluster structure to investigate this issue in a more quantitative manner. The authors first analyze song phonology and then examine song syntax at a population level in 3 species with very different song structure: chaffinches (Fringilla coelebs), zebra finches (Taenopygia guttata), and swamp sparrows (Melospiza georgiana). The authors used a dynamic time-warping algorithm to compare song elements, which closely matched the judgments of human observers. Clustering tendency and validation statistics showed that broad phonological categories existed in all 3 species, but these categories explained no more than half of the overall phonological variation. The authors developed a novel statistic to assess syntactical structure, which indicated that element transitions were not randomly distributed. In the clearest case, in chaffinches, this could be explained by syllables being linked to certain positions within the song. These results demonstrate measures of song organization that can be applied across species, enhancing the potential of comparative studies.
