掌握种群动态以及迁徙习性对濒危候鸟的保护至关重要。2004~2005、2007~2008、2008~2009年的冬季(10月~次年4月),采用夜栖地直接计数法对云南省纳帕海湿地黑鹳(Ciconia nigra)的种群数量进行了监测。结果表明,在2004~2005、2007~2008、2008~2009年冬季,纳帕海湿地越冬黑鹳种群平均数量分别为39.6、128.6、181.8只,呈逐年增加的趋势;通常黑鹳10月下旬迁来,至次年3月中下旬迁离;纳帕海同时也是繁殖于蒙古国的黑鹳迁往印度越冬地的重要停歇地,过境时间集中在 11月中上旬。纳帕海湿地已经成为国内最为重要的黑鹳越冬地和迁徙停歇地,建议当地管理部门加强湿地管理,维持适当的浅水区域作为黑鹳的觅食地,另外需加强旅游管理,减少游客对黑鹳的干扰。
Knowledge of population size and migration ecology is essential for the conservation of endangered migrants. We studied the wintering population size and migration of Black Stork (Ciconia nigra) at the Napahai Wetland in Yunnan province during October-April 2004-2005, 2007-2008 and 2008-2009 by roosting sites counting. Our results showed that the Napahai Wetland was one of the most important wintering and stop-over sites of Black Stork in China. The average population size was 39.6, 128.6 and 181.8 in winters of 2004-2005, 2007-2008 and 2008-2009, respectively. The Napahai Wetland was also an important stop-over site for Black Stork populations migrated from Mongolia to India. The Black Storks normally migrated to Napahai in late October and left in mid-or late March. We suggested local government take effective measures to manage the wetland and protect Black Storks, including maintaining enough shallow water areas as their feeding sites and decreasing human disturbances.
