is a rare and endangered species endemic to Hainan, China. It has long been regarded as a subspecies of the widely distributed Grey Peacock-Pheasant (), a classification that has resulted in a paucity of targeted conservation studies and rendered efforts to protect and restore its populations and habitats exceedingly challenging. In this study, the Jianfengling section of Hainan Tropical Rainforest National Park was designated as the research area. We comprehensively utilized infrared camera monitoring data for and other species, alongside habitat environmental factor data obtained through multiple monitoring approaches. An ensemble species distribution model (ESDM) was employed to evaluate the habitat suitability for four ground-dwelling bird species, including , and to investigate their environmental preferences and competitive interactions during habitat selection. Subsequently, the Marxan model was applied to identify key protection areas for . The results indicate that the suitable habitat for is primarily distributed in the central, eastern, and certain southern areas of the study region, with low spatial overlap and minimal competition from the suitable habitats of the other three ground-dwelling bird species. However, due to anthropogenic disturbances and the inherently stringent habitat requirements of , its overall suitable habitat area is limited, exhibiting a concentrated distribution overall with fragmented, small patches within it. Our study recommends designating the eastern and southern regions of the study area as key protection areas for , thereby providing a robust baseline environment and policy support for the targeted protection of its habitat and the recovery of its populations.
是中国海南特有的珍稀濒危物种。长期以来，它一直被视为广泛分布的灰孔雀雉（）的一个亚种，这种分类导致针对性的保护研究匮乏，使得保护和恢复其种群及栖息地的努力极具挑战性。在本研究中，将海南热带雨林国家公园的尖峰岭区域指定为研究区域。我们综合利用了针对该物种及其他物种的红外相机监测数据，以及通过多种监测方法获取的栖息地环境因子数据。采用集成物种分布模型（ESDM）来评估包括该物种在内的四种地栖鸟类的栖息地适宜性，并调查它们在栖息地选择过程中的环境偏好和竞争相互作用。随后，应用马克思an模型来确定该物种的关键保护区。结果表明，该物种的适宜栖息地主要分布在研究区域的中部、东部和部分南部地区，与其他三种地栖鸟类的适宜栖息地空间重叠度低，竞争极小。然而，由于人为干扰以及该物种本身对栖息地要求苛刻，其总体适宜栖息地面积有限，整体呈集中分布，内部有零散的小斑块。我们的研究建议将研究区域的东部和南部地区指定为该物种的关键保护区，从而为其栖息地的针对性保护和种群恢复提供有力的基础环境和政策支持。
