eBird data from the eBird Basic Dataset (May 2019 Update) and 50-stop data from the North American Breeding Bird Survey Dataset (BBS, version 2018.0) filtered to the US state of Massachusetts during the breeding seasons of 2005-2018. R-script covers the modeling methods and comparative analysis of four indices of annual relative abundance derived from these BBS and eBird datasets.

本数据集包含2019年5月更新版eBird基础数据集（eBird Basic Dataset）的相关数据，以及2018.0版北美繁殖鸟类调查数据集（North American Breeding Bird Survey Dataset，简称BBS）的50样点数据；所有数据均经筛选，限定为2005年至2018年繁殖季内美国马萨诸塞州范围内的有效记录。配套R脚本涵盖了基于上述两类数据集衍生出的四类年度相对丰度指标的建模方法与对比分析内容。
