日本鸟类环志现状和动向

Researches on the Status and Trend of Bird Ring Labeling in Japan

日本是亚洲地区最早开展候鸟环志以研究其迁徙规律的国家,目前不论是年环志鸟的数量,还是回收鸟的数量均居亚洲地区首位。日本鸟类环志自1924年(大正13年)开始,到1943年累计环志鸟类29～66种316983只,回收环志鸟15～41种,计15379只;1944～1960年鸟类环志工作中止36年,1964年开始在日本全国大规模开展环志工作,到1990年,日本鸟类年环志量已达265种126015只。目前日本共有60处环志站(其中1、2级站分别为10、15个),并有大量鸟类环志爱好者参加工作。

Japan is an earliest country in Asia engaged in bird ring labeling and studying thelaw of bird's migration. The annual volume of bird labeling and the number of labeled birdsrecovery all rank first in Asia. The bird ring labeling began in 1924(the thirteen year inTaishao reign) in Japan. Up to 1943,the cumulative total of labeled birds reached 316, 983,including 26～66species. The number of birds recovered amounted to 15 397, including 15～41species. The peried from 1944 to 1960 was a blank. In 1951～1957 an American conduct-ed a research on the ring tabeling of three species of egret in Japan. In 1964, a nation--widering labeling drive was launched. Up to 1960, the number of labeled birds reached 126,015,including 265 species. Now there are 60 Bird Ring Labeling Stations (among which thefirst order and second order stations are 10 and 15, respectively) in Japan. Besides, a goodlot of amateurs are engaged in such work. Now the total of ring labeled birds in Japan is1, 660, 395.
