This report is a collection of recorded observations of migrating waterfowl at Miyajima-numa, which recently became famous as a globally important stop-off point for white-fronted geese that migrate to and winter in Japan. It includes the results of spring observations of white-fronted geese since 1975, and other species since 1981. As for observations made in the autumn, records since 1988 are included, the year before the marsh was essentially made a sanctuary.
While the content of the report includes the arbitrary judgments of observers, the details of each observation have been recorded as faithfully as possible. The observers, who have now been keeping records for a very long time, would be extremely pleased if the knowledge collated in this report could someday be of use.
