【摘要】 1996年1～8月在陕西佛坪自然保护区采用无线电遥测与定点观察相结合的方法对红腹锦鸡的取食活动性进行了研究.红腹锦鸡的取食基地及其植被组成具有明显的季节性变化特征.冬季主要集群取食,同一集群个体常利用同一区域;春、夏季多分散取食,个体间取食活动区重叠较少.气候、食物丰盛度、天敌以及个体间的啄食等级等因素对红腹锦鸡的取食活动有很大影响.不同鸟类之间的混群取食可能有助于提高取食效率或减少天敌捕食压力.更多还原

【Abstract】 The foraging behaviour and activity in the Golden pheasant Chrysolophus pictus was carried out from January to August 1996 in Foping Nature Reserve, Shaanxi province, China, using radio-telemetry and fixed spots observation methods. The feeding habitat of the Golden pheasant varied with seasons. In winter, the Golden pheasant foraged in flocking and the mixed-species foraging groups were often observed, and individuals from one flocking often utilized the same feeding habitat. But in spring and summer, they foraged in different habitats with few feeding habitats overlapping. Weather, food availablity, predation and social hierarchy have important effects on the foraging activity. The mixed-species flocking may increase foraging efficiency or reducted the predation risk.更多还原
