    We reviewed observation records of the Red-billed Blue Magpie Urocissa erythrorhyncha (Corvidae) in Shikoku Island, Japan. This species of magpie, which is native to the Asian continent, is considered to have escaped captivity and been naturalized in western Shikoku. Thirty-three records of this species, dating from 2000 to 2017, were collected from Ehime and Kochi Prefectures. Two records of fledglings confirmed successful breeding. The magpie was observed mainly in secondary forest habitat sites, though they also used conifer plantation and farmland. These observations suggest that this naturalized species has become widely distributed in lowlands of western Shikoku Island.

    This location-related GPS data set for a Whooper Swan Cygnus Cygnus, tracked in Japan in 2016, is provided here to benefit public research. The swan was attached with GPS at the Uchinuma Pond, Miyagi Prefecture, northern Japan. It moved south to Otsuka Pond, Ibaraki Prefecture, where it over-wintered. It then moved to southern Sakhalin via Tokachi, Hokkaido, in March 2017. As it entered Sakhalin, Russia, the swan went out of the GPS-tracking coverage area, and we could not follow the route further north. Although many swans have been satellite tracked before to provide long-distance migration information in East Asia, we are unaware of any GPS-tracking data published to date. GPS data is very detailed and accurate, and has the potential to show details of swan wintering ecology within Japan. Currently, detailed data for swans are of potential value to research in the epidemiology of avian influenza, and to identify the potential impact of wind farm construction on swans. We are providing public access to the data set in order that the public may use it for such purposes.
