1灰鹤在天山木扎提河湿地越冬及行为观察显示文摘于2017年10月—2019年5月,采用直接计数法、瞬时扫描取样法、卫星跟踪和最小凸多边形法(MCP),对新疆阿克苏地区拜城县木扎提河流域灰鹤(Grus grus)的种群特征、活动范围、行为时间分配和行为节律进行调查和分析。结果表明,2019年越冬灰鹤种群数量超过4700只,较2016年增加1倍多,种群发展动态呈上升趋势。灰鹤主要以家庭群为主(63.90%),聚集群次之(28.62%),孤鹤最少(7.48%)。家庭群主要以2成鸟1幼鸟为主(占46.82%),聚集群以5~8只个体为主(占65.91%)。整个越冬期持续140~160 d,灰鹤越冬期活动距离为1058 km,活动区域相对固定,活动区域面积为125 km^2。日活动面积和活动距离随着气温的变化而变化,温度降低,日活动范围和活动距离降低;反之,则增加。因此,活动面积和活动距离呈凹形变化,即先增加(10—11月),再逐渐减少(12—1月),然后增加(2—3月)的变化趋势。取食和警戒是灰鹤的主要越冬行为。灰鹤的46.8%日间时间用于取食,17.8%的日间时间用于警戒,用于休息、走动、理羽和其他行为的日间时间分别占13.4%、11.4%、7.4%和3.2%。日取食高峰呈双凸型,出现在8:00—9:00和17:00—18:00,分别达到57.0%和58.5%。休息高峰出现在11:00—15:00,占24.6%,呈单峰型。研究区灰鹤种群面临着放牧、农耕、天敌、道路车辆、低温和人为驱赶等诸多威胁因素。李军伟 马鸣 孟凡娟 E I Ilyashenko V Yu Ilyashenko O V Belyalov A E Gavrilov S Kh Zaripova N Batbayar 曹垒 2020生态与农村环境学报2020,36,5:4
