Raw body mass data for bird species

These are raw body mass measurements from the vertnet.org specimen database that have already been subject to extensive quality control. All columns other than species binomial and mass in grams have been stripped away; this is the minimal information required to do the bootstrap resampling to recreate the analysis in the manuscript.

本数据集源自vertnet.org标本数据库的原始体重测量数据，已经过全面质量控制流程。除物种双名与以克为单位的体重数据外，其余所有列均已被剔除；仅保留了通过自助重采样（bootstrap resampling）复现本研究手稿中分析流程所需的最少信息。
