Range Description

Columba janthina is an uncommon and local resident in Japan, on small islands off southern Honshu, Shikoku and Kyushu, south through the Nansei Shoto islands to the Yaeyama Islands and the Izu Islands to the Ogasawara and Iwo Islands (BirdLife International 2001). It occurs locally on small islands off the south coast of South Korea, and it has been recorded (presumably as a vagrant) in eastern Russia, Shandong, mainland China and Taiwan (China). Although it is still relatively common on the Izu Islands, it has apparently declined there since the 1950s, and it is thought to have declined on Okinawa during the 1980s because of forestry activities. There are estimated to be only 30-40 individuals of subspecies nitens on the Ogasawara Islands, but the status of this subspecies on the Iwo Islands remains unknown (per Otani Chikara in litt. 2005, Simba Chan in litt. 2005).
