摘    要:越冬期黑颈鹤的个体行为可分为:取食、保养、争斗、警戒、运动行为、种间关系及领域性。随着冬季食物资源的逐渐减少,在取食行为中幼鹤由乞食、被成鹤供食转为向成鹤抢食。有些家族鹤为保证食物资源而建立领域,领域大小与家族内成员数无关,且在冬季(甚至1天内)是变化的。为获得食物和保卫领域,黑颈鹤之间(或与灰鹤之间)常发生争斗,争斗的主要形式是仪式化威胁。

关 键 词:黑颈鹤  个体行为  越冬期

Abstract:Wintering behaviors of Black Necked Cranes( Grus nigricollis) can be put into 7 categories:foraging,maintenance,agonistic,alert,locomotion,interspecific relation and territoriality With the progress of winter,food resources decreased This correlated with a change in foraging behavior of young cranes from begging to grabbing food from their parents Some crane families established territories,presumably to guard their food sources Size the territory,determined by the male or the stronger parent,changed daily and as winter progressed To access food sources or defend the territory,agonistic behavior,mostly in a form of ritualization,was frequently displayed
Keywords:Black  Necked Crane  behavior  ecology  wintering period
