Bird Diversity in Different Habitats at Mamize Nature Reserve in Sichuan Province

The survey on the bird species and numbers was conducted with the method of the point count during April to May 2006 at the Mamize Nature Reserve of Sichuan Province. During the two months survey,1948 individuals of birds were recorded, belonging to 105 species, 23 families and 7 orders. There are 6 species of birds protected nationally, and 7 national endemic species at this Nature Reserve. The analysis about the bird fauna suggests that the East-Asian Group species is dominant. There are four bird communities distinguished according to the habitat. The analysis about the bird diversity of the different habitats suggests that 1)the highest similarity of the bird community is the replanted forest and the shrub meadow, and the lowest is the shrub meadow and the primary forest; 2)the highest bird diversity is the secondary forest, and the lowest is the shrub meadow; 3)the primary forest has the most species of birds protected nationally, and the national endemic species is fewer than the secondary forest; 4) the highest density of the birds in four bird communities is the understorey.
