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.

本数据集包含雀形目鸟类（Passerine species）的如下数据：
- 雌雄个体的季节性羽色（以存在/缺失表征）
- 交配系统（评分区间为0至3：0代表严格社会单配制，1代表存在偶发社会多配制事件的社会单配制，2代表存在常规兼性社会多配制的社会单配制，3代表专化资源防御型多配制或求偶场多配制）
- 父本抚育行为（以存在/缺失表征）
- 性二色性
- 对数体质量
- 地面取食占比（数据源自Wilman等人2014年发表于《生态学》的研究，卷95，页码20-21）
- 繁殖范围内的林木覆盖占比
- 繁殖范围内的降水季节性
- 繁殖范围内的温度季节性
- 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（数据源自Ducatez与Lefebvre 2014年发表于《公共科学图书馆·综合》的研究，卷9，文章编号e89955）
