摘　　要：2018年1月—2019年12月,在湖北省随州市广水市平靖关村布设红外相机25台,记录白冠长尾雉(Syrmaticus reevesii)的活动节律,并对不同年龄阶段和不同性别的白冠长尾雉活动节律进行了分析。结果表明,不同年龄和不同性别的白冠长尾雉日活动节律不同,呈现错峰现象。5—7月是雏鸟集中出现的时期,育雏雌性成鸟有2个活动高峰期,而同期非育雏雌性成鸟有3个高峰期,雄性成鸟高峰期则不显著,不同性别白冠长尾雉的日活动节律有明显差异;7—9月是亚成体逐渐增多的时期,亚成体、同期雌性成鸟和雄性成鸟在清晨、中午和傍晚均有3个高峰期;不同年龄和性别的白冠长尾雉日活动节律重叠程度均较高,其中重叠最高的为亚成体和雌性成鸟,重叠系数达0.96。研究表明,白冠长尾雉日活动节律在年龄和性别间均存在差异,自身生活史阶段可能是造成这些差异的主要原因。同时提出对白冠长尾雉保护建议。With 25 infrared cameras in Pingjingguan Village, Guangshui City, Suizhou, Hubei Province, China, we recorded the activity rhythms of the Reeves’ s pheasants(Syrmaticus reevesii) from January 2018 to December 2019. We conducted a comparative analysis of the activity rhythms of Reeves’ s pheasants across different age groups and different sexes. The results showed that the daily activity rhythms of the Reeves’ s pheasants differed among different age groups and between sexes, showing staggered peaks. From May to July when chicks appeared, there were two peak activity periods for brooding females, three peak periods for non-brooding females, and no peak periods for male adults. From July to September when subadults appeared, there were three peak periods for subadults, female adults and male adults, presenting in the early morning, noon, and evening. The daily activity rhythms of Reeves’ s pheasants from May to July differed significantly between the sexes. The degree of overlaps between different ages and sexes was high from July to September, with the highest overlap between subadults and concurrent female adults(overlap coefficient=0.96). The results highlight the differences in the daily activity rhythms of Reeves’ s pheasants of different ages and sexes. Life history stages may account for their differences in daily activity rhythms. We also make recommendations for the conservation of the Reeves’ s pheasants.
