云南隆庆关秋季鸟类环志研究

STUDY ON THE BIRD BANDING IN AUTUMN IN LONGQINGGUAN,YUNNAN PROVINCE

１９９７年９月２６日至１０月７日，在云南巍山县隆庆关（２５°１８′Ｎ，１００°２１′Ｅ）及其周围地区共网捕到鸟类８７种２５００多只，环志８０种２４１０只。除白日网捕到１０种２２只外，其余皆为夜间网捕。年龄鉴定１１３８只，成鸟与幼鸟的比率约为１∶２，性别鉴定８３９只，雌鸟与雄鸟比率约为２∶１。加上１９９５和１９９６两年同期网捕结果，共网捕鸟类９４种，环志８７种２９４２只，依重要性值（ＩＶ），最重要的鸟类是红喉姬（Ｆｉｃｅｄｕｌａｐａｒｖａ）、树鹨（Ａｎｔｈｕｓｈｏｄｇｓｏｎｉ）和红尾伯劳（Ｌａｎｉｕｓｃｒｉｓｔａｔｕｓ）。此外，还讨论了每日捕鸟数量与天气条件的关系。

More than 2500(87 species) birds were netted and 2410 birds(80 species) were banded in Longqingguan, Weishan County, Yunnan Province (25°18′N,100°21′E). Most of them were netted by night, only 22 birds (10 species) were netted by day. The ratio of adult to young and female to male is about 1∶2 and 2∶1 based on the aging of 1138 birds and sexing of 839 birds. Total of 94 species were netted and 2942 birds (87 species) banded combined with the banding results of 1995 and 1996. The most important birds are red throated flycather ( Ficedula parva) ,oriental tree pipit( Anthus hodgsone) and red tailed shrike ( Lanius cristatus) according to the important value ( IV ). The relation between the birds number netted every night and the weather conditions was discussed.
