Data used for the manuscript titled "Biological significance of song performance limits in birdsong"

The files include a general data table, with acoustic features measured in individual notes that is then used to estimate the performance limits (df.note.before.vocallimits_suppl.txt). The corresponding R script to estimate those performance limits is labelled "r blue tit estimate song performance limits". Then two more data tables are provided, one with normalized data per day, per individual (data.age.season.txt), to model seasonal an age variation and another data set with mean values per individual per breeding attempt (season) to model song correlations with reproductive success (data.rep.sucess.txt)Finally, a short script with the custom made function to track dominant frequencies is also added.

本次提供的文件包含一张通用数据表，其中收录了针对单个鸣唱音符测得的声学特征，这些特征被用于估测鸣唱表现极限（df.note.before.vocallimits_suppl.txt）。用于估测上述表现极限的对应R脚本文件名为“r blue tit estimate song performance limits”。此外还提供了另外两张数据表：其一为按每日、每只个体整理的归一化数据（data.age.season.txt），用于构建季节性与年龄差异的预测模型；其二为按每只个体每次繁殖尝试（繁殖季）统计的均值数据集（data.rep.sucess.txt），用于构建鸣唱特征与繁殖成功率之间的关联模型。最后，本次还附带了一段用于追踪主导频率的自定义功能脚本。
