Continued from the previous report, this one deals with the percentage of works shared between the male and female, territory, predator, family life and reproductive rate, based on the results of outdoor observations for the purpose of studying the life history of the birds in the Zenkoji basin (altitude about 400m) in the northern part of Nagano Prefecture from 1963 to 1964. The main part of the observations was done in the Nagano district in the center of the basin, and most of the life history during the breeding season of the bird was described based upon the observation of one nest in 1964.

1.長野県長野市信州大学教育学部構内で1967年に,キジバト(Streptopelia orientalis orientalis)の繁殖生活を観察した。2.巣造り期間は2~4日。♂は枯枝を嘴で折ったり,地上から拾ったりして巣材運搬のみに従事し,♀は巣場所でそれを受けとり,小枝を組み合わせて巣を造る。3.卵数は4巣において2卵で,1巣のみ1卵であった。抱卵は1卵産卵後から行ない,♀と♂が朝方と夕方2回交代し,♀は夕方から夜間を経て朝方まで平均17時間,♂は昼間の平均7時間続けてだく。抱卵日数は15~16日間であった。4.給餌は♀,♂とも行ない,親の口の中へ雛が嘴を入れ,親は首を上下にふりながら液状の餌を戻して口うつしをする。抱卵は育雛前,中期まで抱卵タイプでの♀♂交代が続き,抱雛しながら夫々の親が給餌する。このため前,中期ほど給餌回数が多く14~19回となり,後期は給餌だけに巣を訪れ1日3~4回である。巣立ちはふ化日から15~17日間である。5.次の繁殖は同じナワバリ内で巣場所をかえて行ない,抱卵期に入ると♂だけが前巣の雛に給餌する。6.キジバトのナワバリはMAYR(1935)の分類のB型に属する。7.繁殖諸仕事の♀♂分担は次のようである。抱卵,抱雛の割合の約70%は♀であり,給餌はその60%が♂である。ナワバリ防衛は90%以上を♂が受けもつ。

1. This study of the breedingbiology of Japanese Greenfich Chloris sinica minor was conducted during March 1966 and August 1968, in an area of 660 ha of farmlands in Nagano prefecture, 400 m of altitude. 2. The study is based on breeding records of 262 nests, eleven all-day observations on breeding pairs and 824 marked individuals.3. The breeding procedure cousisted of five periods: preparatory-nest-building-egg-laying-incubation-chick-raising and famiy-life periods.4. Pair formation is advanced through the male's series of behaviors which are: courtship song-coutship posture to an attracted female-leading the female into a selected nest-tree-following after the female. After pair is formed the female selects the nest site.5. When the female fails to find the nest site within the male's territory, she would wander out of it for seardh of a good site, fllwed by the male. Therefore, the first territory is abandoned.6. Early in the breeding season, before middle April, they work for nest-building only in the morning and diappear in the afternoon to join the flock.7. The female only builds the nest and the male follows her closely.8. The nest-building period varies from about 14 days in the earlier part of the season, before 5 April, to as short as 4 days after entering May.9. This is due to the situation that in early season they feed on seeds left from the previous year and need time in foraging, their nest-building and egg-laying are prolonged. Later in the season, they can efficiently feed on rich source of new grass seeds and therefore finish neting in a short time and lay eggs at onde.10. The egg is usually laid one each day early in the morning. There were three exceptions (out of 68 caseg) in which eggs were laid in less than 24 hours.11. Day incubation is commenced after laying the first egg of clutch but true or night incubation sets in after the clutch has been completed.12. The female only incubates and is fed by the male. This feeding is usually (76.9%) performed at exposed places outside of the nest (The female may remain to be fed in the nest when she is conscious of observer) and never in the nest-tree. The feeding spots are concentrated along the territory border 20-40m from the nest and at least 8m it. Judging by the observer's personnal experience this has advantage to protect the nest from predator.13. The incubation period varied between 12 and 15 days but 40.6% were 12 days and 46.9 % 13 days.14. A clutch hatched in 1-3 days, with 89.4% in 2 days.15. Both sexes engaged in feeding the chicks and the frequency was 11 times a day This very low rate as compared with those in insect-eating passerines is due to the presence fo the crop in which the parents carry and chickc store the food.16. The chicks' growth of body weight slown in later stage and slightly decrease before nest-leavin, but the quills grow continuously. The tail is still short on flying.17. Teh feeding period of nestlings was 12-17, usually 14-15 (51.7%), days. After flying chicks were fed by both parents for 7-10 days and a few pairs commenced the second brood.
