Data for: Evolutionary drivers of seasonal plumage colours: colour change by moult correlates with sexual selection, predation risk and seasonality across passerines

This data file contains the following data for passerine species: - Seasonal plumage colours for males and females (presence/absence)- Mating system (scored from 0-3: 0 = strict social monogamy, 1 = social monogamy with infrequent instances of social polygyny observed, 2 = social monogamy with regular facultative social polygyny, and 3 = obligate resource defence polygyny or lek polygyny)- Paternal care (presence/absence)- Sexual dichromatism- Log body mass- Percentage ground foraging (obtained from Wilman et al. 2014. Ecology, 95, 20–21)- Percent tree cover within the breeding range - Precipitation seasonality within the breeding range- Temperature seasonality within the breeding range- Migration status (0 = resident, 1 = partial migration and 2 = complete migration)- Research effort (obtained from Ducatez and Lefebvre 2014. PLoS One, 9, e89955)Species names (TipLabel) match those at www.birdtree.org. For further details (including source references), please see the accompanying research article.

本数据集文件包含雀形目（passerine）物种的如下数据：
- 雌雄个体的季节性羽色（以存在/缺失进行标注）
- 交配系统（采用0~3分制评分：0代表严格社会单配制；1为存在偶发社会多配制现象的社会单配制；2为存在常规兼性社会多配制的社会单配制；3为专性资源防御型多配制或求偶场多配制）
- 父本抚育行为（以存在/缺失进行标注）
- 性二色性（sexual dichromatism）
- 体重对数转换值
- 地面取食占比（数据来源于Wilman等人2014年发表于《Ecology》第95卷第20至21页的研究）
- 繁殖范围内的林木覆盖率
- 繁殖区域内的降水季节性
- 繁殖区域内的温度季节性
- 迁徙状态（0为留鸟，1为部分迁徙，2为完全迁徙）
- 研究投入量（数据来源于Ducatez与Lefebvre 2014年发表于PLoS One第9卷e89955号的研究）
物种名称（TipLabel）与www.birdtree.org平台上的对应命名一致。如需获取更多细节（包括参考文献来源），请参阅随附的研究论文。
