准噶尔盆地东部波斑鸨秋季种群动态简报

Preliminary Study on Autumn Population Dynamic of Houbara Bustard in Eastern Jungar Basin

对木垒繁殖区波斑鸨秋季迁飞前种群动态的研究发现 ,秋季波斑鸨有集群现象 ,多以家族或成体与亚成体组成小群 ,数个小群集合形成大的迁飞群。秋季波斑鸨的警觉性非常高 ,距观察者 30 0 - 10 0 0m甚至更远 ,即惊飞。与夏季分布区相比 ,秋季波斑鸨分布区向西南移动约14km至E90°36’。

Studies on population dynamic of Houbara Bustard before migration in autumn in Mulei Breeding-ground showed that, Houbara tended to gather in groups in autumn. Small groups were made of family or adults and sub-adults. And the aggregation of these groups formed large flocks. The vigilance of Houbara was high in autumn and will be flushed at 300-1000m from the car. Compared with the range of summer, the distribution of Houbara in autumn drifted and moved southwestward to E90°36',about 14km far from Camp1.
