    First, the history of the lake as waterfowl resort (less than 20 acres) and later artificial interferance are mentioned. After the war, eight swans (C. c. cygnus) were first noticed on January 28, 1950, by Mr. J. Yoshikawa, by whose painstaking effort not to alarm them, and by effective help of Mr. K. Nitta, the swan increased to 42 on February 17 (46 birds in March). The maximum of 27 birds in 1951, 39 in 1952, 33 in 1953 and 32 in 1954 have been recorded. Yoshikawa's effort to tame the swans was such that he or his asistants must watch the boys and dogs day and night, as the lake froze to allow them reach the swans. Then, after great offort, the stream water was poured into the lake to keep it free from freezing, and the swans were fed with grains. In the third year of feeding, his effort was proved fruitful as the swans became so tame as to come to him at his calling voice to eat grains a few meters from him. They were however watchful to the voice of the other persons. As the lake is in the village, there are still occasional annoyance, for example, the fireworks.

    On January 25, 1955, the author visited Torishima, a well known 'albatross island' belonging to the Izu Islands. The Steller's Albatross, Diomedea albatrus, once believed to be extinct from this island, was rediscovered by his friend inApril, 1954. On his visit, the author, with help of others, estimated 23-25 birds to be the optimum number. They were nesting on a pebbly grassy sand slope of 20-30°, where was well protected from seasonal NW winds by the surrounding cliffs. Only three chicks of a chicken size were found, and there were three abandoned eggs. Most individuals were adults, none of the black juvenile (and only a few subadult with black nape) having been seen. Some were observed flying to and from the slope, but seemed to make off only 4km. at the most. The "albatross village", so called by the people of the Weather Station, which is the only establishment on the island, is being given a well managed protection, though occasional landing of fishermen is suspected.
    The storm petrels, Oceanodroma tristrami, make their nest holes in every inch on the northern slope, covered by grass-tendril network. Some were found dead or dying tangled by these tendrils at the mouth of the holes. Eggs were being incubated, but curiously, many were laid on the ground. It has, however, markedly decreased recently, because its night cries have become far the less noisy than during the pre-war or war times. Its decrease is apparently due to the damage by cats and dog found in wild state, which are also the menace to the albatross chicks. Few falcons are another predator to not only the petrels but also the small land birds resident or wintering on the island. They are therefore extremely shy, and the White-eye was found to be extinct from the island, while few species were first observed. Fast protective measure from the predators is deemed necessary.

    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.

    A bird apparently of this species, Anser erythropus, was observed by the author November 3, 1954, at a marsh area near cape Shiriya, Aomori, the northern end of Honshu. Next day it was no more found. Judging from its former record (Saito, Tori, No. 64), the bird was apparently on migration from southern coast of Hokkaido.

    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.
