Records of the Bluethroat Luscinia svecica, in Hokkaido

Abstract

There have been five records of Bluethroat Luscinia svecica, from Hokkaido. All are capture records except for one that is unclear in detail. There has been no direct observation record. Among the four capture records, one was obtained in the latter half of September and three in early October. These occurrence records are markedly earlier than those in the southern half of Japan. There has been no record in winter seasons. It is highly probable that Bluethroat recorded in Hokkaido are accidental visitors while undergoing their autumn migration.
