Abstract: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 redthroated flycather (Ficedula parva),oriental tree pipit(Anthus hodgsone) and redtailed shrike (Lanius cristatus) according to the important value (IV). The relation between the birds number netted every night and the weather conditions was discussed.
