摘　　要：2002年4～5月,在黑龙江省长林岛自然护保区对白枕鹤春季迁徙期的各种行为活动节律及时间分配进行了实地调查研究.结果表明,白枕鹤在春季迁徙期的各种行为具有较强的规律性.觅食、游走、警戒、静息是白枕鹤的4种主要行为,所占的时间分配百分比分别为75.05%、13.00%、6.78%、2.46%.早晨5:50～8:00和中午12:00～15:00是白枕鹤的觅食高峰期.静息行为与觅食行为节律成反向关系变化.鸣叫、理羽、求偶、交配和打斗行为节律在一天中没有多大变化.A study was conducted to investigate the activity rhythms and time budgets of Grus vipio during the spring migration season from April to May in 2002 in Cha nglin Island Nature Reserve.
