海南山鹧鸪Arborophila ardens是海南岛特有的，位于中国南部沿海。银雉的不同亚种Lophura nyethemera xvhiteheadi和灰孔雀雉Polyplectron bicalcaratum katsumatae也是岛上特有的。这三个分类群都被认为是濒危物种，在野外鲜为人知。在1987年至1994年期间，对剩余的森林进行了调查，期间对当地居民进行了采访，并访问了一些森林地区。山鹧鸪从三个街区的森林中得到证实，另外四个街区也有报告。在森林的六个区域发现了银雉，并且可能出现在所有剩余的发育良好的次生林和原始林斑块中。在五个森林中记录了灰孔雀雉，并报告了另外四个森林的情况。山鹧鸪的生境利用比其他两种更受限制，后者除了原始林外还利用发达的次生林。巴王岭国家级自然保护区的临时密度估计为海南山鸡6-8只/km2，银鸡7.5只/km2，灰孔雀3.75只/km2。
Summary The Hainan Hill-partridge Arborophila ardens is endemic to the island of Hainan, which lies off the south coast of China. Distinct subspecies of the Silver Pheasant Lophura nyethemera xvhiteheadi and Grey Peacock-pheasant Polyplectron bicalcaratum katsumatae are also endemic to the island. All three taxa are considered endangered and are very poorly known in the wild. Surveys of remaining patches of forest were undertaken between 1987 and 1994 during which local people were interviewed and some forest areas were visited. The hill-partridge was confirmed from three blocks of forest and reported from a further four. The Silver Pheasant was found in six areas of forest and probably occurs in all remaining patches of well-developed secondary and primary forest. The Grey Peacock-pheasant was recorded in five forests and reported from a further four. The hill-partridge was more restricted in its habitat use than the other two species, the latter using well-developed secondary forest in addition to primary forests. Provisional density estimates made at Ba Wang Ling National Nature Reserve were 6–8 Hainan Hill-partridges/km2, 7.5 Silver Pheasants/km2 and 3.75 Grey Peacock-pheasants/km2.
