A long term field monitoring work, from May 2004 to November 2010, on birds in Jiangxi-Wuyishan National Nature Reserve has brought the following positive results—263 bird species (under 148 genera of 51 families of 17 Orders) being recorded with 216 species of photos, about 19.8% of the Chinese birds as far known. G-F index analysis indicating remarkably higher the diversity at family level than in other taxon of the locality; field studies also revealing less difference of species diversity of birds appeared in all kind of habitats below the tree line of about 1900 m, whilst, between 800-1 900 m, birds more preferring to the original forests and those secondary woods recovering for over 30 years, those areas hence being the core habitats for birds. Wuyishan is also functioning as a refuge supporting a small and isolated population of some of those birds mainly occurring in Himalaya-Indo-China or Himalaya-SW China, and, the local population of the Cabot's Tragopan (Tragopan caboti) might be considered the healthiest one in nature, with the longest knowledge and understanding of our species, the human being, on the bird.
