摘要
2004年通过地面和航空调查等方法,对繁殖于小兴安岭沾河流域的白头鹤(Grusmonacha)种群进行了数量调查,共统计到白头鹤30只。发现了3对鹤的巢;2对以及2只单只的个体,虽然没有发现巢,但根据其保护领域的行为,可以确定其为繁殖个体。同时统计到13只没有参加繁殖的个体,以及3只不能判明是否参加繁殖的个体。通过本次调查表明,小兴安岭沾河流域的森林沼泽是我国白头鹤的重要繁殖地。
The population size of Hooded Crane（ Grits monacha ） at their breeding site was conducted by ground and aerial censuses in 2004 at Zhanhe River valley, Lesser Xingan Mountains, Heilongjiang Province. A total of 30 Hooded Cranes were recorded, in the mean time 3 nests were located. From the territory defending behavior, 2 pairs of birds and 2 single Cranes were confirmed to be breeders. Moreover, 13 were recognized as nonbreeders and the breeding situation of 3 more birds was not able to determine. This survey confirms that the swamp of Zhanhe River valley, Lesser Xingan Mountains, is an important breeding site for Hooded Cranes in China.
