摘　　要：2020年2月—2021年2月,采用直接观察与红外相机陷阱结合的方法,在四川唐家河国家级自然保护区的大草坪和大草堂区域,对绿尾虹雉Lophophorus lhuysii的繁殖周期及群体活动模式等进行了研究。共获取绿尾虹雉有效探测316次。研究结果表明:1)绿尾虹雉具有季节性群体活动的习性,群体在繁殖期前逐步解散,繁殖期后又逐步聚集,非繁殖期的越冬期会结成大群活动;2)绿尾虹雉的繁殖期为3月下旬—6月中下旬,雌性独自营巢繁殖,雄性多单独活动,也表现为集单性小群体活动;3)繁殖期群体大小为2.58只±0.94只,以单性群为主;非繁殖期群体大小为3.37只±2.30只,以单性群和雌雄混群为主,且两者的遇见率差异不明显;繁殖期和非繁殖期群体活动方式无显著差异。本研究结果丰富了绿尾虹雉的基础资料,为其保护管理策略的制订提供了科学依据。From February 2020 to February 2021,the breeding cycle and group activity patterns of Chinese monals(Lophophorus lhuysii)in the Dacaoping and Dacaotang area of Tangjiahe National Nature Reserve(Sichuan)were studied.By combining direct observation with camera traps,a total of 316 efficient detections were obtained.The results showed that:1)there is a seasonal grouping activity in the population,and L.lhuysii will gather after breeding season,especially in winter;2)the breeding season is from late March to mid-to-late June.While the females nested by themselves,most males tended to move solely,or took actions in smaller monosexual groups;3)during the breeding season,the average group size is(2.58±0.94)individuals,and monosexual group is the dominant group pattern;in the non-breeding season,the average size of group is(3.37±2.30)individuals,and groups mostly presented in the form of monosexual group or sexual-mixed group with no obvious difference in the encounter rate.There is not a significant distinction in the group activity patterns between breeding and non-breeding seasons.This study will enrich the fundamental ecological data of L.lhuysii and provide scientific basis for the development of conservation strategies in the reserve.
