Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range-restricted or threatened species

This dataset contains long-term monitoring data of breeding territories of Bonelli’s Eagle (Aquila fasciata) and Golden Eagle (Aquila chrysaetos) in the Betic mountain ranges (southern Spain) collected between 1980 and 2020. Data include territory identity, annual occupancy, nesting substrate, reproductive performance, and spatial coordinates. Monitoring was conducted using standardized field protocols across decades, providing one of the longest continuous datasets available for large raptors in Europe. The dataset supports analyses presented in: Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range-restricted or threatened species Coordinates may be spatially adjusted to prevent disturbance of sensitive breeding sites. Users are encouraged to contact the authors prior to reuse to ensure correct interpretation of long-term monitoring protocols.本数据集收录了1980年至2020年间，在西班牙南部贝蒂科山脉（Betic mountain ranges）收集的博内利雕（Bonelli’s Eagle, Aquila fasciata）与金雕（Golden Eagle, Aquila chrysaetos）的繁殖领地长期监测数据。 数据涵盖领地标识、年度占用情况、营巢基质、繁殖表现及空间坐标。本监测工作采用标准化野外规程持续数十年，所形成的数据集是欧洲目前可获取的最长的大型猛禽连续监测数据集之一。 本数据集支撑了下述研究的分析工作：《对于西班牙两种曾遭人为迫害、以悬崖为主要营巢生境的雕类而言，树上营巢与悬崖营巢效果相当甚至更优——界定分布受限或受威胁物种种栖息地的警示案例》（原英文标题："Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range-restricted or threatened species"）。 为避免干扰敏感繁殖位点，空间坐标可进行空间调整处理。 鼓励使用者在复用该数据集前联系原作者，以确保对长期监测规程的正确解读。
