2013年云南碧塔海自然保护区鹤类及大型水禽的数量与变化

Number of wintering cranes and waterbirds at the Bitahai Nature Reserve, Yunnan, China in 2013

摘要: 2013年1月17—19日,在云南碧塔海省级自然保护区对采用夜栖地直数法对黑颈鹤(Grus nigricollis)、灰鹤(G. grus)、斑头雁(Anser indicus)、赤麻鸭(Tadorna ferruginea)、黑鹳(Ciconia nigra)的数量进行了调查。共记录到黑颈鹤36只、赤麻鸭4只。与10年前相比,黑颈鹤的夜栖分布发生了较大变化,主要夜栖地点由吉里谷转到了弥里塘湿地。这可能跟吉里谷湿地人为干扰增大有关。
