Rank : 3
Passage Migrant
The species is famous for its migrating in large flocks from Irago Misaki in Atsumi Peninsula and Sata Misaki in Kagoshima Prefecture to the south. During its migration season, the species is seen passing through Asakawa River basin. We at Kawasemi-Kai have been conducting observational research of the migration of this species every year between end-September and the beginning of October at several observation spots in this area. According to our record, the migration has been observed on some days as many as over one hundred, showing this area is one of the migratory flight paths of the species. The species breeds in woodland not far from populated area, although the breeding has been declining because of the regional development. The species is classified as gEndangered Species IIh in the Red Data Book of Ministry of the Environment.
