云南纳帕海自然保护区越冬猛禽考察初报

Wintering Observation of Birds of Prey in Napahai Nature Reserve,Yunnan

纳帕海自然保护区位于滇西北香格里拉县,是湿地鸟类迁徙途中停留觅食的"驿站"和越冬地。2006年冬至2007年春对保护区冬季猛禽资源进行了3次调查,共设4个观察点,采用瞬时扫描取样和目标取样法对各猛禽的状态行为、生境利用和事件行为进行数据采集。共观察记录猛禽1目2科9种。猛禽种群分布和数量与保护区鸟类资源变化密切相关。白尾海雕和高山兀鹫的越冬行为主要是觅食、休息和运动。行为的变化受食物丰富度的影响明显。通过有效保护湿地内的环境、其它鸟类资源和科学管理,对本地区的猛禽资源保护有重要作用。

Napahai Nature Reserve is a seasonal lake and important international wetland located in the northwest of Yunnan Province. Napahai Reserve is a “Store Over” of migratory birds and a wintering habitat for many wetland migrants. Three surveys for birds of prey were carried out at Napahai Nature Reserve from Winter 2006 to Spring 2007. Scan sampling and focal animal sampling methods were used to collect data. Totally 9 species recorded belong to 2 Families and 1 Order. Community amount and distribution of the prey birds are relative to the resource change. The most behaviors of white-tailed sea eagle （Haliaeetus albicilla） and Himalayan griffon （Gyps hinalayensis） were foraging, resting and locomotion during wintering season. These behaviors emerging were affected by the food abundant. It is important for birds of prey to protection by efficacious managing or utilizing wetland environment and birds resource.
