Species temperature index by Japan Breeding Bird Atlas. Species recorded at over 30 sites

From 2016 to 2021, a national survey of birds has been conducted as "Japan Breeding Bird Atlas" We conducted two complete survey courses within each cell of a 20km square mesh (total 2344 courses) placed as a graticule over the map of Japan. Using this data, we determined the average temperature of breeding birds in Japan. The mean temperatures of the distribution areas of various bird species (species temperature index: STI) weighted with number of individuals were calculated. Species recorded at over 30 sites were indicated.

自2016年至2021年，我国开展了一项名为‘日本繁殖鸟类图鉴’的全国性鸟类调查。在覆盖日本地图的20公里网格单元内，我们进行了两次完整的调查课程（总计2344次课程）。利用这些数据，我们确定了日本繁殖鸟类的平均温度。计算了各种鸟类分布区域的平均温度（物种温度指数：STI），并按个体数量进行了加权。在超过30个地点记录的物种被标注出来。
