The Grey Thruth Turdus cardis is a common species breeding in the forests on hillsides and mountains.However, its breeding in the urban areas of central Kanto Plain has not been reported previously.We have found this species nesting at Kamifujisawa, Iruma City, Saitama Pref., in June 1980. The locality is only 111 m above sea level.
It is likely that the Grey Thrush is expanding its range from the mountain areas into the plains, as a result of the recent recovery of favorable environment in urban areas.
