摘　　要：红喉雉鹑(Tetraophasis obscurus)是中国特有种,国家一级重点保护野生动物,研究其繁殖季的夜栖地选择,能丰富该物种的基础资料,理解其生存策略,为该物种的保护和深入研究提供科学依据。2021年和2022年的3~7月,采用跟踪观察和系统搜索法,对四川王朗国家级自然保护区繁殖期红喉雉鹑的夜栖行为和夜栖地选择进行了调查,共记录夜栖地样方34个。采用卡方检验、配对样本T检验、Mann-Whitney U检验和逻辑斯蒂回归模型方法对数据进行分析。红喉雉鹑主要夜栖于方枝柏(Sabina saltuaria)等针叶树,常见1只单独夜栖或2只共同夜栖,未见有集群夜栖;夜栖树通常位于上坡位,距离林缘和最近乔木较近,具有较大的胸径和郁闭度,栖枝距离地面高度6.6 m左右,栖枝长度约1.66 m;夜栖地具有较大的坡度和落叶盖度,而灌木盖度较小。安全因素(夜栖树胸径、坡度)和食物因素(落叶盖度)是红喉雉鹑选择夜栖地的最关键因素。[Objectives]Chestnut-throated Pheasant(Tetraophasis obscurus)is an endemic species in China and a national Class I key protected wildlife.The study of its roosting habitat selection during the breeding season can enrich the basic information of this species,improve understanding of its survival strategy,and provide a scientific basis for the conservation and in-depth study of this species.[Methods]From March to July of 2021 and 2022,roosting behavior and roosting site selection of Chestnut-throated Pheasant in Sichuan Wanglang National Nature Reserve during the breeding season were investigated by tracking and systematic search method,34 roosting habitat samples were recorded and 24 environmental factors were measured(Table 1).We first used the chi-square test to analyze the preference of Chestnut-throated Pheasant for slope location.When analyzing the differences between the environmental factors in the roosting samples of Chestnut-throated Pheasant and the random samples,the K-S test was used to determine whether the data conformed to a normal distribution,and the T test for matched samples was used for data that conformed to a normal distribution,and the Mann-Whitney U test was used for data that did not conform to a normal distribution.Environment factors with significant differences were included in a binary logistic regression after Spearman’s correlation analysis to determine the key habitat factors affecting the choice of the roosting habitat of Chestnut-throated Pheasant during the breeding season,and all analyses were performed using SPSS 25 and MuMIn package in R 4.2.1.[Results]The Chestnut-throated Pheasant mainly roosts in coniferous trees,such as Sabina saltuaria,and it is common to roost alone or with another individual,but not in a group.Data analysis revealed significant differences in slope,diameter at breast height of the roosting tree,coverage of trees,average diameter at breast height of trees,coverage of shrub,coverage of leaf,distance to the forest edge,and distance to the nearest tree be
