During the period covered by this report, 56, 062 birds of 174 species were banded at the thirty banding stations which are scattering over 17 prefectures from the northernmost part of Hokkaido to the western end of Yamaguchi Prefecture (see Fig. 1 and Table 1.)
The numbers of birds banded and re-caputured by banding station are shown respectively in Table 2, and Table 3.
Birds which were banded at a banding station and caught again at the same area next season or thereafter are called here 'returns'. During this period, a total of 2, 303 returns of 24 species was recorded. The data of returns are shown by individual bird, and by bird banding station.
Recoveries of birds banded are totaled to 206 birds of 26 species of which 74 individuals of 13 species were reported from abroad, but only one domestic recovery of the banded abroad was obtained during the period.
Among the above recoveries, the specially interested are described under the item 'Notable Recoveries'. In the explanation to the recoveries, the widely believed migration route of thrushes and buntings right across the Japan Sea is questioned by the author because of no evidence from bird banding that supports the hypothesis.
