摘要
白尾地鸦属于中国特有物种 ,仅仅分布于新疆的塔克拉玛干沙漠。从 1874年定名以来 ,人们始终不清楚这个种的繁殖习性、地理分布及数量状况等。本文根据十几年的野外调查 ,特别是那些来自沙漠腹地“死亡之海”的考察结果 ,显示白尾地鸦广泛散布于沙漠之中 ,从北纬 3 7°～ 4 2° ,东经 77°～ 90° ,海拔 80 0～ 15 0 0m之间。根据笔者 1988年以来的 10余次路线统计及上百个分布地点的调查分析 ,白尾地鸦分布至新疆南部 2 0多个县市 ,面积约13 .5× 10 4km2 范围内。粗略估计其分布密度为 0 .0 3～ 0 .0 5只 /km2 ,数量为 4 10 0～ 670 0只。应该尽快被纳入国家重点保护动物名单。
Xinjiang Ground Jays (Podoces bidduphi) are a kind of very special and local species in China, they only habit in Taklamakan Desert, south Xinjiang(Ludlow & Kinnear 1933,Qian Y. et al.1965,Grimmett 1991,Ma Ming et al. 1992, Collar et al.1994,Madge & Burn 1994,Ma Ming et al.1997,Ma Ming 1998, Ma Ming et al. 2000). Since the species was found and named by Hume in 1874, very few people had studied or knew the species in China, and it is hard for the modern ornithologists to explain the geographical distribution, breeding ecology and present situation of population of the ground jays. From 1999 to 2001, we are fortunate to get the financial suppot from Hong Kong Bird Watching Society to engage in research work on the birds. It is surprised that the jays reside in the central area of Taklamakan Desert all the year round. They were found hundreds times in the central area of the desert, i.e.,in the area from 77°E to 90°E and 37°N to 42°N, about 800～1500 meters above sea level. The total area of distribution is about 1.35×10 5km 2including 20-24 counties, e.g. Aksu, Luntai,Korla, Lopnur, Ruoqiang, Qiemo, Niya, Keriya, Qira, Lop, Hotan, Moyu, Guma, Yarkant, Markit, Maralbashi, Awat,etc. The distribution density of the birds is 3-5 birds per hundred km 2, and the population is about 4100-6700 birds. We hope that the species can be placed listed in the ' Lists of Important Wildlife Protected in China' as soon as possible.
