Sensitivity analysis of collision risk at wind turbines based on flight altitude of migratory waterbirds

This dataset contains information on the distribution of geese and swans and the three-dimensional flight trajectories. The former was obtained through vehicle field surveys, interviews, and a literature review. The latter was obtained using ornithodolites., Collection of bird distribution
The foraging and resting flocks of swans and geese were located and recorded at the stopover sites and in the wintering areas by vehicle. A cumulative total of approximately 60,000 km2 of farmland (including pastures, rice fields, and cropland), in addition to bodies of water, including rivers, ponds, and lakes was covered. The surveys were carried out for a total of 101 days: nine days in Niigata Prefecture (from November 2018 to February 2019), four days in Yamagata Prefecture (in February 2019); 10 days in Akita Prefecture (in February and November 2017); 11 days in Akita Prefecture (in December 2018 and February 2019), 10 days in Aomori Prefecture (March 2018 and March 2019); five days in Miyagi Prefecture (in November 2017); and 52 days in Hokkaido (in March and April 2017, March and April 2018, and March 2019).
