Body mass dynamics of migratory nightjars are explained by individual turnover and fueling

''Body mass Red-necked Nightjars'' dataset includes measurements from a long term study (2011-2019, N = 882 measurements) taken in a population of Red-necked nightjars (<i>Caprimulgus ruficollis</i>) in Doñana National Park, located in the southwest of the Iberian Peninsula. The weight and the stomach (gizzard) volume were measured from the captured individuals. ''Capture-recapture data for calculation of FDR'' datased includes measurements from this same long term study (2011-2019, N=166 measurements) of Red-necked Nightjars. In this dataset, only individuals recaptured after 24.00 pm were included and body mass were corrected for stomach (gizzard) size. Further details on the field procedures are provided in the article.<br>

红颈夜鹰体重数据集收录了2011-2019年一项长期研究的测量数据，共包含882条记录，研究对象为栖息于伊比利亚半岛西南部多尼亚纳国家公园（Doñana National Park）的红颈夜鹰（Red-necked Nightjars，*Caprimulgus ruficollis*）种群。研究人员对捕获个体的体重及砂囊（gizzard）体积进行了测量。
用于计算假发现率（False Discovery Rate，FDR）的标记重捕数据集同样源自上述长期研究（2011-2019年），共包含166条红颈夜鹰的测量记录。该数据集仅纳入当日24:00后被重捕的个体，且已针对砂囊体积对体重数据进行了校正。野外操作流程的详细细节可参见相关研究论文。
