The dataset of ”The Wintering Bird Atlas of Japan” (2016-2022)

From 2016 to 2022 we completed a second survey of "The Wintering Bird Atlas of Japan". With the cooperation of 396 participants, 105,660 questionnaires were collected across Japan, and combined with 788,148 data from other sources and databases. The information was aggregated into a national set of grid cells of approximately 40 km square, and compiled as a distribution map. We release this dataset to provide data to researchers and conservationists who wish to conduct various analyses to evaluate the distribution of birds in Japan during this period.

自2016年至2022年，我们完成了“日本越冬鸟类分布图”的第二次调查。在396位参与者的协作下，全日本范围内共收集到105,660份问卷，并与其他来源和数据库中的788,148条数据相结合。这些信息被汇总成约40平方公里方格的国家级数据集，并编制成分布图。我们发布此数据集，旨在为研究人员和保育工作者提供数据，以支持他们进行各类分析，评估此期间日本鸟类分布状况。
