本文于1987—1989年三个冬季间,对太原南效区的寒鸦种群动态进行了研究。研究结果表明,本区4月份寒鸦数量最少,骑自行车每时行程6公里可遇见寒鸦131.7只,12月数量最多,骑自行车每时行程6公里可遇见寒鸦3834.7只。其种群结构中,成鸟:幼鸟=1:2.33;雌鸟:雄鸟=1:0.96,为扩展型种群。冬季食物以农作物和杂草种子为主,分别占总食量的42.32％和41.50％。 This paper studied the population dynamics of jackdaws in the Southern District of Taiyuan during the winter of 1987-1989. The results showed that the number of jackdaws in April was the lowest in this region. 131.7 jackdaws were found in 6km per hour when riding bicycles.
