Turdus celaenops is a distinct species of thrush confined to the Seven Islands of Izu except Torishima. Its visit to the main island was recorded on five occasions. T. dissimilis of Burma and Yunnan, T. seebohmi of Borneo, T. obsourus, T. hortulorum and T. chrysolaus of the Palacarctic region are considered near relatives to T. celaenops. It is suggested that celaenops, chrysolaus, obscurus and dissimilis were derived from a same ancestral stock on the Asiatic continent and since the arrival of one strain to the Seven Islands, through selections and mutations, the present form, celaenops, was developed. Because the general resemblance in the plumage and the wing formula, celaenops is nearest related to chrysolaus.Yakushimensis, the only known subspecies in Yakushima, is not considered valid and; as these subspecies have been taken only in October, Yakushima birds were probably migrants from the Seven Islands. Parallel cases are phylloscopus occipitalis ijimae and Luscinia akahige tanensis, the Seven Islands breeding subspecies which are known to winter in Yakushima and further south to the Ryukyu Islands.

Judging by the personal reports received by the author from lighthouse keepers in various parts of Japan, the following may be suggested as possible behaviour of night migrants, particularly the Passrines. 1) The passage of night migrants is noticed offshore rather than ashore where there are islands and capes to avoid, and they fly low close to the seasurface. 2) As generally said, they migrate in clear nights, but when the sky suddenly became overcast or rainy, they may be lost and if a lighthouse were close enough its dim light may attract them. In such cases, some of them die struck at the lighthouse and others spend the night nearby to start again in the next favourable evening. In clear night this never happens. 3) The second case of migrant destruction at lighthouses occurs when the weather was good during the day and became cloudy or rainy towards evening. On such a day, migrants gathering around lihthouse at a cape where there are usually good cover for rest, become restless to start for night flight, but the sudden overcast condition urges them only to fly around the light and some or numbers of them will strike at it. 4) Stronger the light the more migrants are attracted from greater distances and the lighthouse at more unstable weather condition is responsible for more migrant victims. 5) In recent years, however, the birds struck at lighthouses has become extrmely fewer, owing possibly to: a) the genereal decrease of bird numbers and b) increase of coastal village lights and lights of fishing boats on the coastal seasurface.

A new subspecies, Accipiter virgatus iwasakii, subsp. nov., was described as a smaller resident Riu Kiu race with more rounded wing-formular compared with the northern(Korean)form. Its known range is Ishigaki and Iromote islands of the South Riu Kius.The Riu Kiu population of Anous stolidus is smaller and paler than that of Micronesia, A. s. pileatus (Scopoli). Therefore the name, A. s. pullus Bangs, is to be recognized for the birds of Ishigaki and Iriomote islands, S. Riu Kius.

Akune in Kagoshima had been a well known crane resort of a long history. Since about 30 years ago cranes moved to Arasaki, with numerous other water fowl. During the war, they decreased abruptly by successive poaching, but in recent few years they are again increasing. The Spoonbill (Platalea) which was formerly rare has increased to over 20 birds. Five Bean Geese and others were seen associating with the flock of cranes (See photographs). A list of 33 resident, 47 winter, 17 summer and 13 transient specis, is given.

Flocking of <i>Delichon urbica</i> around a big abandoned chimney in Miyako City, Iwate, was observed during 1959-1961. There were no distinct correlations with weather, food, air current or breeding conditions, other than the fact that they gathered on calm fine mornings (with wind velocity less than 3), and increased in number from July to September and October. They seemed only enjoy-a sociable flocking around a distinct object on the way of migration.

The author obtained a Rough-legged Buzzard, Buteo lagopus pallidus, shot alive 7 December 1954 at Hanno-gawa, Kahoku-machi, Momou-gun, Miyagi Prefecture. Its feeding behavior for various foods, fish meat, rat, mink, bird, frog, sanke, and animal meat, etc., are reported. The bird was first fed with fish but later disliked it and frog or snake, though they were finally eaten. It took 1325g. of food at a time and 2kg. a day. Fatty meat was not its taste. After it ate a poisoned rat, given by mistake, it dared a 8-days fast and after this it used to throw animal's viscera. Showed inherent skill in catching a thrown food, drank water almost every morning, and took small pebbles when sprinkled in the cage. Reported also about its pellet, which is digorged 24-60 hours (usually 24-36 hours for feathers) after the food was taken.
