I capture incubating or brooding Grey Starling in nesting boxes by hand. I am always careful to avoid nest desertion by ensuring that:
1. Before capture, I identify that both the male and the female are involved in incubation.
2. After I identify that an un-marked bird incubate more than twice, I capture the bird at least 6 days after incubation.
3. If both male and female are captured, I identify that the first-captured bird is incubating before capturing the other bird.

From February 1979 to February 1991 at Obihiro, eastern Hokkaido, 69 Turdus naumanni (TN) and 14 T. obscurus (TO) were captured and ringed with a numbered metal ring. TN were captured in spring and autumn migratory seasons, and during the winter. TO were captured only in the autumn migratory season. Numbers of birds captured per net-days differed from year to year. Birds were recaptured only within the season they were ringed. The average body weight of TN was 75.7g in October and 77.4g in February, decreasing slightly to 73.2g in March. Prior to the spring migration, body weight increased significantly to an avarage of 94.6g in May. The average body weight of TO was 65.9g September and 65.2g in October.

From April to June, 1991, the number of Whimbrels (Numenius phaeopus) were counted at Yatsu tidal flat, Narashino, Chiba, in central Honshu (35°41′N.140°00′E). During the spring migration, the first Whimbrel was seen on 17th April. From the first arrival, Whimbrels increased rapidly in number. The peak occurred on 10th May when 522 birds were seen roosting in a flock. After the peak, the number of birds soon decreased. In July no birds were observed in the study area.

I have been banding Tree Sparrows, Passer montanus, at Ueno Zoological Gardens from 1977 to 1991. 427 Tree Sparrows (152 nestlings, 182 juveniles, 93 adults) were banded during this time. Of the 334 nestlings and juveniles, 6 returned and were recovered at their birth-place. I presume that food abundant at this banding site (the West Garden: about 2 ha) and that it also has numerous nesting and roosting places, so that the adult survival rate is high. Therefore, most juveniles disperse from the area. However, there was little difference in juvenile return rates between present study and other studies conducted at snowy regions of Japan. In the future, I will investigate factors influencing juvenile return rates.
