An Oriental Plover Charadrius veredus was observed at the Hachijo-jima Airport, Hachijo-machi (33°07′ N, 139° 47′ E) on Hachijo-jima, Tokyo from 2nd to 3rd May, 2006. In comparison with the Pacific Golden Plovers Pluvialis fulva that were presented nearby, this individual was slightly smaller, its legs were longer, and its bill was comparatively thinner and longer. The upperparts, including the head and the wing coverts, were pale brown. The supercilium was white and reached the forehead. The underparts were white and the breast was pale buff. This species has been recorded only in Ibaraki and Chiba Prefecture in the Kanto area and has never previously been recorded in Tokyo, including the Izu and Bonin Islands.
