摘要
观察348个标本的中央尾羽,测量其性状并统计,结果表明:1)雉科8种中央尾羽色斑格局不相同;2)中央尾羽长、内翈宽、外翈宽都存在显著差异(P<0.05),以白冠长尾雉中央尾羽(118.3±18.89)cm最长,内翈(2.44±0.21)cm最宽,以红腹锦鸡外翈(2.80±0.82)cm最宽,而灰胸竹鸡的中央尾羽(9.51±0.78)cm最短,内翈(1.02±0.13)cm和外翈(0.99±0.10)cm最窄.以上有助于分辨雉科此8种鸟类.
The phenotypes of 348 central rectrice samples were observed and measured. The results showed that: 1 ) the color patterns of 8 species central rectrices are different; 2) The differences of length central rectrics of 8 species, as well as the width of inner web and outer web are significant(P〈0.05). The central rectrics of Syrrnaticus reevesii is the longest(118.3±18.89) cm, and the width of inner web(2.44 ±0.21 ) cm, the outer web of Chrysolophus pictus (2.80±0.82) cm is the widest. The length of Bambusicola thoracica (9.51 ± 0.78) cm is the shortest in 8 species central reetrics, and the width of inner web (1.02 ± 0.13 ) cm and outer web (0.99± 0.10) cm are for the minimum value. The above mentioned differences are helpful to classify 8 species in Phasianidae.
