Data_Variation in wing morphology is related to breeding environment in a high-elevation specialist bird

This database include morphological and environmental data used in paper 'Variation in wing morphology is related to breeding environment in a high-elevation specialist bird?', Journal of Avian Biology (DOI 10.1111/jav.03007). Measured birds were captured during the breeding period with mist-nets and spring traps at 55 different sites within 10 study areas in the central-eastern Italian Alps during spring/summer 2021. Primary feathers lengths (P9-P1) were measured by a metal ruler (± 0.5 mm). Age and sex were determined according to Svensson (1992) and Demongin (2016). At each capture site, percentage cover of vegetation categories within a 100-m radius was visually estimated in the field to the nearest 5%, and variables estimated to cover less than 5% of the plot were assigned a 1% cover value.

本数据库包含发表于《鸟类生物学杂志（Journal of Avian Biology）》（DOI: 10.1111/jav.03007）的论文《高海拔特化鸟类的翼形变异与繁殖环境相关？（Variation in wing morphology is related to breeding environment in a high-elevation specialist bird?）》中所使用的形态学与环境数据。2021年春夏季节，研究人员于意大利阿尔卑斯山东中部10个研究区域内的55个不同样点，使用雾网与弹簧陷阱在繁殖期捕获了受试鸟类。研究人员采用金属直尺（精度±0.5 mm）测量了受试鸟类的初级飞羽长度（P9-P1）。受试鸟类的年龄与性别依据Svensson（1992）与Demongin（2016）的标准进行判定。在每个捕获样点，研究人员于野外以目视方式估测100米半径范围内各植被类别的盖度，估测精度为5%；对于估测盖度低于5%的植被类别变量，统一赋值为1%的盖度值。
