Abstract:[Objectives] Human activities have significantly transformed the natural ecological environment of the region, leading to notable impacts on the spatial utilization patterns of local animal populations. Consequently, gaining insights into the spatial requirements of endangered species under conditions of human disturbance becomes crucial for their effective conservation. Home range and habitat utilization serve as paramount indicators of an animal’s spatial needs, and comprehending the characteristics of home ranges and habitat preferences becomes imperative for bird conservation efforts to yield optimal results. [Methods] In this study, we employed the “noose method” to capture individuals and researched the breeding season home range of Reeves’s Pheasants (Syrmaticus reevesii) using satellite tracking. The fixed kernel (FK) density estimation was utilized to estimate the home range and assess the habitat utilization of each individual. By analyzing the percentage of recorded locations within specific land types, we evaluated the habitat utilization of Reeves’s Pheasants. The theoretical habitat utilization was determined by calculating the percentage of each land type in relation to the total study area. To assess the habitat selection preference of Reeves’s Pheasants, we compared the confidence interval of actual habitat utilization with the numerical values of theoretical habitat utilization. Our analysis focused on three key factors associated with human disturbance:the intensity of human disturbance, distance to farm, and distance to residential areas. We performed a stepwise elimination analysis using generalized linear mixed models (GLMM) to examine the factors influencing habitat utilization and home range size of the Reeves’s Pheasants. [Results] From 2020 to 2021, we have collected home range and habitat utilization for 47 individuals. The results showed that the Reeves’s Pheasants mainly utilize mixed coniferous forests, deciduous broadleaf forests, and shrub forests (Table 1). However, when classified according to disturbance intensity, the Reeves’s Pheasants in low-disturbance areas tend to use mixed coniferous forests only (Table 2). In high disturbance areas, the utilization rate of deciduous broadleaf forests by female individuals shows little change with respect to the distance to residential areas and farms, while the utilization rate of mixed coniferous forests increases as the distance to residential areas and farm increases. In low disturbance areas, as the distance to residential areas increases, the utilization rate of deciduous broadleaf forests decreases, but the utilization rate of mixed coniferous forests increases. Additionally, as the distance to the farm increases, the utilization rate of deciduous broadleaf forests also increases, but the relationship between the utilization rate of mixed coniferous forests and the distance to the farm is not as pronounced (Table 3, Fig. 3). The utilization rate of male individuals in deciduous broadleaf forests or mixed coniferous forests is not influenced by disturbance intensity. The utilization rate of male individuals in deciduous broadleaf forests decreases with increasing distance to residential areas and increases with increasing distance to farms. Neither the distance to residential areas nor the distance to farm affects the utilization rate of male individuals in mixed coniferous forests (Table 3, Fig. 4). The home range of females (18.19 ± 1.59 hm2, n = 28) was significantly larger than that of males (12.39 ± 1.52 hm2, n = 19), and the home range size of females was negatively correlated with the distance to residential areas in the high disturbance area (Table 4, Fig. 5). [Conclusion] These findings enhance our understanding of the spatial requirements and habitat preferences of the Reeves’s Pheasants, shedding light on the influence of human disturbance on their behavior. Our study offers valuable insights into the behavioral responses of Galliformes to ongoing human activities, taking into account factors such as human disturbance, sex, home range, and habitat utilization. Through a comprehensive examination of these factors, our objective is to establish a solid scientific basis for the conservation of ground-nesting forest birds.
