Abstract
Social hierarchy was studied in two flocks (14 and 10 individuals, respectively) of captive jackdaws. Parent birds acquired high-ranking positions during the nesting period. Outside the breeding season the hierarchy seemed to be stable. Males generally dominated females. When the top-ranking male arrived at the feeding place it tended to supplant one of the feeding birds rather than choose an unoccupied site.
摘要
对两群圈养寒鸦（分别为14只和10只个体）的社会等级制度进行了研究。亲鸟在筑巢期获得了较高的地位。在繁殖季节之外，等级制度似乎是稳定的。雄性通常主导雌性。当地位最高的雄性到达喂食地点时，它倾向于取代其中一只正在进食的鸟，而不是选择一个未被占据的地点。
