 | | The Yufutsu Moor district contains various habitats for birds, such as ponds, marshy grasslands, and except for the southern coastal side, most of them are surrounded by low hills covered by the broad-leaved forest. |
| | At Lake Utonai, which is the largest pond in this district, and its surrounding moor, 46 species of transient brids, consisting mainly of wading birds, were recorded, and furthermore, a large number of winter water-falls were observed to continue migrating after stopping briefly in this area, with only a few individuals staying through out thewinter. |
| | Therefore, the Yufutsu Moor was considered to be a very important route of migrations for many species of water birds. |
