The wintering ducks at the Shinobazu Pond in Ueno Park were observed from September 1974 to April 1977. The Shinobazu Pond was divided by the stroll ways into three parts, the Zoo part, Hasu Pond part and Boat Pond part where hired boats were floated between 9:00 to 17:00. In the Zoo part, the daily feeding for wild ducks has been continued since 1954. The routine observations were carried out at 7:30 - 8:30 in the morning.
The results obtained were as follows:
1. An annual increasing of the wintering ducks was continually noticed as shown in Fig. 1. The main reason for this fact was seems to be in fanciers' feeding at early morning in Boat Pond and in the daily feeding in the Zoo part.
2. Throughout the observation periods, 14 species including two rare species in Japan, the American Wigeon and the Ring-necked Duck (the first record in Japan; FUKUDA, 1977) were observed (Table 1). In their population, the Pochard and the Tufted Duck increased greatly, the Mandarin Duck decreased gradually and the others did not change generally.
3. On the sex ratio, the males were usually predominent over the females in most species (Pintal, Mallard, Teal, Wigeon, Shoveler and Pochard) except the Tufted Duck (Table 2).
4. On the distribution of the ducks in the Shinobazu Pond, the Pintail and Wigeon increased in Boat Pond. Nevertheless of the remarkable increase of the Pochard and Tufted Duck, their numbers in Boat Pond decreased gradually (Fig. 4).
5. The movement of the ducks in the three parts of the Shinobazu Pond might depend on the feeding time (at 9:30 - 10:00 and 15:30 - 16:00). And it seems to be their daily repeated behaviour that they moved to the Zoo part in the daytime and returned to the floating area by the next morning.
6. From the annual observations, the constituent members of the wintering flock were accepted as inconstant members to some extent, and they had a tendency to lose their regular habitual situation in the Shinobazu Pond.

Observations were made on waders at Lake Toufutsu, situated in the eastern Hokkaido, from 1972 to 1975. This lake is of a brackish water by connecting with Okhotsk Sea at the north-west end. Here visit numerous birds in spring and autumn, and a total of 32 species of waders were recorded by this study. This figure is greater than that in Mukawa-river (Kobayashi et al, 1975).
Waders were observed at various habitats which were divided as follows:: a) in the water far from shore. b) mud flat, c) lake-shore. d) in the marshaland near shore. Two phalarope species and two godwit species (Limosa limosa and L. lapponica) occurred frequently in habitat a), but the former was observed in the pond near lake-shore, and the latter in the water over 2 m apart from shore-line. 21 species were observed on the lake-shore, while 19 species were recorded on the mud flat. Tringa ochroppus, T. glareola, Gallinago gallinago and G. hardwickii frequented the marshland behind the lake-shore, but often appeared on the latter for feeding.
Waders began to appear from mid-August, and the number of species rapidly increased from late August to early September. The number decreased fastly to the 19, October, but increased again thereafter.
Percent of occurrence of species showed seasonal changes. Calidris ruficollis was most abundant each month and Charadrius mongolus and Calidris alpina was next commonest.

The author observed on the egg-laying by Cuckoo Cuculus canolus in the nest of the foster-parents the Bull-headed Shrike Lanius bucephalus, at 11th June 1977, in Shiojiri city central Honshu. The results obtained were as follows;
1) The female Cuckoo deposited her egg directly in the nest of the foster-parents.
2) It took only two seconds to deposit her egg there.
3) The egg was laid at 17:41.
4) The author did not observe that the female Cuckoo took away the eggs of the foster-parents.
5) It was observed that the pair of the Cuckoo might cooperate each other in the egg-laying.
