Plumage coloration in passerine birds

Plumage colour scores (N=5831 species) and predictor variables (N = 2471 species) in passerine birds. This data set includes plumage scores for males and females as calculated from RGB (red, green, blue) values measured from plates in the Handbook of the Birds of the World (see text of article for details). Additionally we include the values of the 5 key predictor variables: 1) body size (first phylogenetic principle component (PPC1) of body mass and wing length), 2) tropical life history (PPC1 of latitude, seasonality and clutch size), 3) sexual selection (PPC1 of mating system, sexual size dimorphism and paternal care), 4) cooperative breeding (no = 0 and yes = 1) and 5) migration (none = 0, partial = 0.5 and complete = 1). All predictor variables were scaled to a mean = 0 and standard deviation = 1. These variables were used in the multiple predictor phylogenetic generalized least squares model, Markov Chain Monte Carlo generalized linear mixed models and phylogenetic controlled d separation path analysis (Table 1b, Figure 4 and Figure 5 of the article respectively). Scientific names, English names and TipLabels correspond to the phylogenetic trees provided by www.birdtree.org (Jetz, W., Thomas, G., Joy, J., Hartmann, K., & Mooers, A. 2012.

鸣禽（雀形目鸟类）的羽色评分（N=5831个物种）与预测变量数据集（N=2471个物种）。本数据集包含依据《世界鸟类手册》（Handbook of the Birds of the World）中鸟类标本板的RGB（红、绿、蓝）值计算得到的雌雄个体羽色评分，详细方法参见论文正文。此外，本数据集包含5个核心预测变量的取值：1）体型大小：基于体重与翼长的系统发育主成分第一轴（phylogenetic principle component, PPC1）；2）热带生活史：基于纬度、季节波动性与窝卵数的系统发育主成分第一轴；3）性选择压力：基于交配制度、性体型二态性与父本育幼行为的系统发育主成分第一轴；4）合作繁殖：无合作繁殖记为0，存在合作繁殖记为1；5）迁徙模式：无迁徙记为0，部分迁徙记为0.5，完全迁徙记为1。所有预测变量均已标准化至均值为0、标准差为1。上述变量被分别应用于多预测变量系统发育广义最小二乘模型、马尔可夫链蒙特卡洛（Markov Chain Monte Carlo）广义线性混合模型，以及系统发育控制d分离路径分析（分别对应论文表1b、图4与图5）。数据集内的物种学名、英文名以及TipLabels均对应www.birdtree.org提供的系统发育树（数据来源：Jetz, W., Thomas, G., Joy, J., Hartmann, K., & Mooers, A. 2012. 时空维度下的全球鸟类多样性. 《自然》, 491(7424), 444-448）。
