    著者はニューギニア在住の写真家で,1967年NHKと浦本昌紀氏の一行を本種の生息地に案内して協力されたが,今回貴重な一連の写真を本誌に寄せられた。ここに掲載して深く感謝の意を表する。
    この種は,ニューギニア北西部の7,000~8,000フィートのHerzog山中にすみ,山路に沿う約2マイルの距離に6ケ所の跳り場を発見した。これは若木の葉を取り去り,根元に4~5インチに苔を積み,約12インチの広さの周囲の草をつみとり,苔を敷き,その外周を高めて輪とし,若木の幹のまわりに小枝を組み上は張り出すようにする。この構造は約1ケ月でできる。驚かすとその材料で別なところに柱をつくる。また,葉を噛んでつくったものを組んだ小枝の端にひっかけて飾りとする。飾り終ると常に同じ場所から出てゆき近くの枝から雌を呼ぶ。雌がくると跳り場にじっとうづくまって雌を見上げてその動作を見守る。雌が跳り場近くに降りると雄は枝を組んだ柱の反対側にかくれ"ジシシン"という音を発する。雌が去ると雄は後を追い呼び返そうとする。何回か来た後雌は去らずに柱をよく調べ,雄に向って跳ねる。雄はすぐ柱の反対側にかくれ,こうして円舞場で長いときは15~20分跳る。昂奮が高まると雄は長い冠を開き頭を左右に振って冠を傘状に水平に展開しかくれていた黄と橙の内部の羽毛をパッと見せる。雌が去ると2,3分は虚脱状態にあるが,柱を手直しして,しばらくの間跳り場を去る。しかし2ケ月の観察にもかかわらず交尾を見ることはできなかった(編者訳)。

    1. This is the third year report on the result of monthly bird censuses made during April 1967 and March 1968 in the Imperial Palace along a same 4km route, usually 10.00-12.00 a.m. The census in the Akasaka Palace was not made this year.
    2. A wooded area of Fukiage, with ponds and watercourse and the moat area with duck winter resort and summer heron colony, were separately tallied.
    3. In Fukiage area, for example, the average number of species recorded per day, with seasonal change in species, was 19.4, 16.6 and 15.8 in years 1965, 1966 and 1967, and the average number of birds recorded per day was 215.5, 179.8 and 163.4 respectively; thus slightly decreasing.
    4. The annual tallies of species recorded were 56, 54 and 52 in years 1965, 1966 and 1967, but new species were added in 1966 and 1967, the totals increasing to 64 and 73 species respectively.
    5. The relative abundance of species was compared by occurrence rate, mean number, dominance rate and density index (√mean no.×occurrence rate %) for years 1965, 1966 and 1967.
    6. It was confirmed by eight all day counts that the Carrion Crow flocked as winter resort in the Imperial Palace as in the previous year and up to 1500 birds were tallied comming in to the Palace from the morning feeding place (but possibly not roosting). This flock disappeared in April. The Jungle Crow, on the other hand, is permanently resident in the Palace in a flock of scores. These appear to be a nonbreeding young group, and nesting territorial pairs have been found nesting at various places of outer part of the Palace and at 1km apart from it.
    7. As a rare straggler, the hoopoe was added to the bird list of the Palace.
    8. Feral cats may be influencial as predator especially to the Green Pheasant which showed decrease, and five examples of other birds found by scattered feathers may have been also due to the cats.
    9. Nine herons were seen dead, presumably poisoned by insecticides in their feeding grounds.

    The National Science Museum's project of biological field survey for 1967 included the avifaunal investigation of Mt. Hayachine in Iwate of which no report is published yet. The author was appointed to this and made field studies during 29 June and 4 July.
    The mountain, 1913m at the summit, is the highest peak of the east-west ridge. The north side foot zone is at the elevation of 600m of altitude, ascending as an extensive gradual and then steeper slope, grading from the oak zone, mixed desciduous forest, needle-leaved forest, dwarf forest, Pinus pumila to rocky zones. The south side is very abrupt near the summit and beech forest is developed on the foot zone, the lower part merging to the oak zone with some deforested parts down to 500m of altitude.
    Bird censuses by line transect method were made on both sides, except for the steep upper south slope (owing to rainy days) and a comparative avifaunal analyses were made. Forty four species, 42 on the north side, 28 on the south side, were recorded, and 8 species were added to Mr. Kuzu's unpublished bird list which includes winter birds. These make an total of 85 species recorded from this mountain.
    The north side avifauna shows a fine vertical distribution of bird species according to the forest types and was richer than on the south side where upper vertical forest divisions were lacking. The results are compared in tables and relative densities were calculated by number of birds per 1km, 1 ha, (also 40 ha for total) and 1 hour. For calculation, the highest number recorded for a same route was used, except for density per hour in which the total of numbers recorded in total census time was used. Breeding pair density was calculated for several species recorded by territory songs. Some discussions are given on factors influencing the census records. The efficiency was much better in some morning and with slow pace censuses than those of afternoon or with faster pace.
    Only a few birds were collected for food analysis, and a wren specimen was so distinctly darker and fully barred as to be readily distinguished from typical Honshu birds. The observation of a Turdus pallidus suggests its possible breeding unreported from Honshu. These points are left for future.

    Seasonal distribution and ecology of migrant bird populations were studied by mist-netting and banding primarily in the area of Kyungi-do, Korea from 1st January to 31st December, 1967. During this period of 355 days, 48, 995 birds of 94 species were banded and there were 202 recoveries of 11 species, including 146 returns in Korea and 21 recoveries of 5 species from abroad. Noteworthy records of 16 species observed by the authors and one subspecies new to Korea are given, each with notes on banding and collection records. See text for each species.

    1.1964年から1967年の間に,長野市川中島東部地区でオナガの冬季塒配置と地域群分布について調査した。
    2.地域群の数は30群であった。それらの行動範囲は,塒を中心とした場合160~2,800mで平均802mであった。また,塒が日中行動圏内にある場合は,160~760mで平均433m,塒が日中行動圏外にある場合は300~2,800mで平均1,072mであった。
    3.地域群の個体数は9~45羽で平均22.9羽であった。また,日中行動圏の面積は,約11~42haで平均21.8haであった。
    4.日中行動圏内の個体密度は1ha0.5羽から2.08羽で,平均1.03羽であった。また,当地域全体では,総個体数687羽,面積約27km2で1km2当り25.4羽(1ha0.25羽)であった。
    5.地域群の分布は,第3図のようで,部落とそれに沿った果樹園の分布と深いつながりが認められ,水田地帯には分布しなかった。
    6.塒配置は,第4図のようであった。各地域群は塒への集中性から,いくつかの塒群にまとめられた。塒群は安定塒群と不安定塒群にわけられた。

    Analysis of contents of 39 stomachs of Nucifraga caryocatactes japonicus and 14 of Apus pacificus kurodae of Japan, formerly collected and preserved by late Mr. J. Ishizawa, are reported, as one of the series of studies based on his material kindly given to the author.
    1. The nutcracker consumed far more amount of Pinus pumila seeds than other items in number and frequency, especially in February and March when the seeds are younger. The ptarmigan of the same area prefers older seeds and its suggested relation with the nutcrackers that it makes use of the latter's stored seeds is untenable. 15 animal items, including a Microtus and a Hyla, were identified and Curculionidae outnumbered others among insects.
    2. The swift's diet consisted of 92% Formicidae, followed by Ichneumonidae 57%, Vesperidae and Elateridae 28% each. In the insect Orders, frequency % were: Hymenoptera 92%, Coleoptera 57%, Hemiptera 21%, Orthoptera 14% and Diptera and Lepidoptera 7% each.

    On November 19, 1967, one female Great Crested Grebe, Podiceps cristata, a rare species, was obtained on Lake Toyano-gata, Niigata City, one of the largest alluvial lakes near River Shinano on Japan Sea coast. After preserving it in 10 to 15% formalin solution, various parts of the body and internal organs were measured and weighed (with % for body weight). They are shown by tables and figures. Stomach contents were analysed and illustrated.
