    From 1979 to 1989 76 birds of Dendrocopos major (DMA) and 22 birds of D. minor (DMI) were ringed with a numbered metal ring and a combination of celluloid coloured rings in the farm and campus of Obihiro University and its surrounding areas, eastern Hokkaido. Of 31 adult males of DMA ringed, 50% disappeared within 1 month and 3% were observed in the study area for 6 years. Of 25 adult females ringed, 70% disappeared within 1 month and were not observed after the fifth year. More juveniles disappeared than adults. Of 76 birds, ringed 17 were observed for 1 to 6 years. They occurred in wood islands in the university farm and the wooded areas of the campus. Of 22 birds of DMI ringed only 9% were observed for 1 year or more.

    Ringed Plover is a rare migratory or wintering bird in Japan. One Ringed Plover wintered at the mouth of Kawashiri River, Taturuhama, Nanao-Nishi bay, Ishikawa prefecture (37°10′N, 136°90′E) from 25th October 1988 through 20th April 1989. It seems that study area and unfrozen parts of the Gamou tidal flat are the northern limit of their wintering regeon in the Far East for this species. In this survey, the bird prefered tidal flats to paddyfieled. It foraged mainly on polychaeta worms and the other smaller items. From October 1988 to December 1988, we couldn't find any characteristics to age sex it. Breast-band and mask patterns in summer plumage suggested it to be an adult male.
