Hainan partridge (Arborophila ardens) and Hainan peacock pheasant (Polyplectron katsumatae) are two endangered birds endemic to Hainan Island, and among the national first-class protected species of China. Due to limited concern and fieldwork study, the biological character, geographical range, population, and habitat of these two pheasant birds are still largely unknown. To fill these gaps, we sampled 47 grid cells with a size of 5 km × 5 km in Hainan and established a key monitoring region with an area of 48 km2 in Jianfengling National Nature Reserve. We aim to observe these two pheasant birds using the line transect method, cameras trapping, wildlife recording, and aerial vehicles. After one year of observation, we obtained some primary results of their geographical ranges, distribution patterns, population, and the structure of the animal community they inhabited. As population growth and increasing urbanization result in deforestation and biodiversity loss, we call for focusing on the conservation of these two pheasant birds and protecting our planet earth via this video.
