最近，Pearse等人使用大型公民科学数据库和机器学习技术探索了雀形目鸟类歌声的宏观生态学。他们使用频率标准差（SDF）作为歌曲复杂性的替代品，发现SDF与生活史特征（如一夫一妻制和性二态性）之间的相关性只有微弱的支持。他们发现，歌曲的复杂性随着生产力更高的环境和更温暖的地区而增加，这似乎与之前的几项多分类研究相矛盾。通过比较SDF分数与传统使用的歌曲复杂性指标（音节库大小和每首歌的音节类型的数量），我们没有发现任何相关性的证据。这可能有助于解释他们的发现与以前的研究结果之间的差异。虽然我们同意，可以在多个高度可变的物种之间进行量化和比较的简单指标对于大规模分析鸟鸣复杂性的进展至关重要，但SDF的生物相关性仍然不清楚，需要更多的研究来澄清其与鸟鸣复杂性的进一步研究的相关性。
Recently, Pearse et al. explored the macroecology of passerine song using a large citizen science database of bird songs and machine learning techniques. They used standard deviation of frequency (SDF) as a surrogate for song complexity, finding only weak support for correlation between SDF and life‐history traits such as monogamy and sexual dimorphism. Their finding that song complexity increases toward more productive environments and warmer areas seemingly contradicts several previous multitaxonomic studies. By comparing SDF scores with traditionally used song complexity metrics (syllable repertoire size and the number of syllable types per song), we found no evidence of any correlation. This may help to explain the discrepancy between their findings and findings of previous studies. While we agree that simple metrics that can be quantified and compared between multiple, highly variable species are crucial for progress in large‐scale analysis of birdsong complexity, the biological relevance of SDF remains unclear and more research is needed to clarify its relevance for further studies of birdsong complexity.
