Four trips to the easternmost part of Hokkaido for avifaunal observation were made in the vicinity of Hanasaki Harbor during three periods in summer and once in winter, i. e. 11-13th of June, 1964, 21st of July and 10-11th of August, 1965, and 11th of January, 1966. A total of 56 species of birds were recorded.
Among them, Gavia arctica viridigularis, G. stellata, Melanitta nigra americana, Histrionicus histrionicus pacificus, Rissa tridactyla pollicaris, Larus hyperboreus pallidissimus and Uria lomvia arra, which had been reported as winter birds in Japan, were actually observed during summer time in the above area. One individual (sex unidentified) of Aethia psittaculus, hitherto recorded as stray birds in Japan, was also observed on the sea south of Moyururi Island.
Though we had had no breeding record of Phalacrocorax urile in our country, excepting on the Islands of Yururi and Moyururi, two nests of this species with eggs were found each year on the coast of Hanasaki Bay. The nesting sites of Phalacrocorax pelagicus and Uria salge inornata were newly found in our survey area, i. e. on the Pacific coasts, although their breeding had been previously recorded only on the coasts of Japan Sea.
On Kamoiwa Island the nesting sites of the birds belonging even to the same family were found fairly apart from one another and under quite different environmental conditions as follows:
On the other hand, the birds of some different families, Larus schistisagus, Phalacrocorax capillatus and Uria salge inornata made a common, peaceful colony on top of the island.
The number of sea-birds found around Moyururi Island appears to have steadily increased year after year during the past seven years.
Brief discussions on some species, other than those mentioned above, were also made from zoogeographical and ecological points of view.

The snow bunting has hitherto been considered in this country as a stray bird or a rare winter visitor to Hokkaido. In 1961 and 1963 the writer observed, however, relatively large flocks (consisting of 30-200 birds) of this species three times in and around Sapporo County, Hokkaido. One individual of them was caught in Ishikari County near Sapporo, its stomach contents being analyzed as given in Table 1. The measurements of the specimens accessible to the writer, including 17 specimens of the Natural History Museum, Hokkaido University, are shown in Table 2. All the records known to the writer, including unpublished personal communications, of capture and observation of this species are summarized in Table 3. These twenty-seven records tell us that it might be found in Japan from September 15 to March 22. Six of these records are from Honshu and four of them were observed at Hakui, Ishikawa Prefecture, being reported to concern probably the same 2 individuals observed four times intermittently in the same area. One snow bunting was caught at the mouth of river Kurobe, Toyama Prefecture. These five cases suggest that the snow bunting might be considered as stray birds in these localities situated in lat. about 37°N. The remaining one record, on the other hand, is of 24 birds captured at Shonai (lat. about 39°N), Yamagata Prefecture, and suggest the possibility of its being a winter bird rarely migrating to the south in North-eastern Honshu. Finally in Hokkaido (lat. about 41.5-45.5°N), where relatively few persons are known to observe birds on open fields in wintertime, the snow bunting may possibly be a common winter bird, rather than to be stray birds or rare winter visitors.

Kashiwazaki coast on Japan Sea side in Niigata Prefecture is known as a place where sea birds (also fishes and turtles) are washed ashore and land bird migrants are disturbed. This is due to the particular position of this town, with Sado I. at 60 km offshore and surrounded by mountains behind. In March 1965 about 500 Rissa tridactyla were seen from the shore and 150 (or more) dead birds (of which 80% were young) were collected during 23-31 March by 5 persons and the auther examined 12 _??_ _??_ 4 _??_ _??_, were found during March 1 unsexed. Sixteen Calonectris leucomelas, 12 _??_ _??_ 4 _??_ _??_, were found during March and April 1965 and on each in 1962 and 1964. This species is observed migrating offshore during towards north in this season. Dead birds are found after strong weather and have empty stomachs and their feathers are often spoiled by ship oil. Notes on local weather conditions are given.

An adult female accompanied by 8 ducklings of Mergus serrator and an female with 3 ducklings of M. merganser were observed swimming over Reservoir Iwamatsu on July 8 and 9, 1964. This reservoir, ca. 3 km long and ca. 800 m wide, lies in the central part of Hokkaido, being surrounded by summer forests of Betula Maximowiczii, Quercus mongolica, Ulmus Davidiana japonica, Cercidiphyllum japonicum, Tilia japonica, Acer mono, etc.; a drag road and a forest railroad run together along its eastern coast (Fig. 1).

Interspecific relations of House Swallows H. rustica and Striated Swallows H. daurica, breeding in Kashiwazaki City, Niigata, were studied in five seasons, 1959-1963.
The House Swallows bred widely, nested by single pairs, and mostly (92%) selected the wooden houses of the peripheral part of the city, while the Striated Swallows concentrated in the central part where they used mortar houses and nested in groups. But there was a tendency of the Striated Swallows to expand to the peripheral part and to nest singly, dominating over the House Swallows.

Ishizawa (Tori No. 76) considered that Siphia mugimaki takes his "Second migratory route" on Japan Sea side. On 10 May 1957, the author observed 4 males at Takaoka City on this route. They were singing in cherry trees. On 11 May one female only (also singing in small voice) was confirmed. The occurrence of this species was first recorded during the author's regular census since 1954, and its stay is short as some of other migrants.

This experiment was an attempt to cross golden pheasant and domestic fowl(Japanese bantam).
Chicken semen of white Japanese bantam was inseminated into golden pheasant hen. Two hybrids hatched from 23 eggs set usually on the 21.5 day of incubation. Down color of the hybrids was white. Two hybrids lived to adult. Plumage color of one hybrid was bar of blue on white ground and other was spot of dark brown on white ground.
Golden pheasant semen was inseminated into brown Japanese bantam hens. One hybrid hatched from 60 eggs set usually on the 21.5 day of incubation. Down color of the hybrid was soft brown. Hybrid lived to adult. Plumage was spot of dark brown on yellow color ground.

Large Indian Pratincole, of the southern type, has hitherto been considered as a stray bird, but recently it has often been reported that the bird may irregularly fly over into this country, though very few in number.

Date of collecting: September 23, 1963
Place of collecting: Rice fields at Gyotoku, Ichikawa, Chiba Pref.
Number of the birds collected: Large Indian Pratincole (semi-adults), 2.
