Using a stripsampling method, the birds resource was investigated at three areas (Tianpingshan, Sanmujie and Doupengshan) of Mt. Badagongshan, Hunan in summer from 2002 to 2004. Further more, Shannon-Wiener index (H′) and Pielou evenness index (J) of birds was calculated. Seventy-seven species belonging to 10 orders and 27 families are recorded. Among of them, there are 22 summer migrant and 55 resident species; 6 class Ⅱ protected wildlife of China and 7 provincial protected species; 43 oriental, 18 paratactic and 16 widespread species, and its geographical variation is Oriental realm, Huazhong section, and Western hilly area-highland sub-section. Analyses show that the bird diversities of Tianpingshan, Sanmujie and Doupengshan mainly relate to the area elevation and human disturbance, that is elevation lower, and habitats diversity higher, then H′ also higher; human disturbance higher, then J lower. The H′ and J values of Mt. Badagongshan are 1.5838 and 0.8395, respectively, are lower than those of Hupingshan, where the elevation is the lowest, and higher than Wulingyuan, where has been developed a tourist enterprise, in North-west of Hunan.
