Abstract
Birds are important for the ecosystem by providing various ecological service. The diversity and the structure of the birds in different landcover were investigated in mining concession of PT. Vale Indonesia. Using the point count and line transect method, we conducted a study of diversity, structure and the distribution of birds in four different landcover: i) High-Density Forest- ii) Moderate Density Forest- iii) Low-Density Forest- iv) Shrubs. Data were collected from February to March 2020. Fortynine species of 29 families were recorded. Among all we found 14 endemic species of Sulawesi, 2 species are near-threatened species and 1 species is vurnarable species. The species composition in Moderate Density Forest was more similar to High-Density Forest than to shrubs. The availability of food resources and the characteristic of the vegetation may be vital to the diversity of birds in every habitat. Therefore, this study indicates that land-cover change and modification may affect bird diversity structure, and the maintenance of the vegetation as food resource and as habitat is essential for bird conservation. On the other hand, the diversity of the bird can help the succesion of the forest and support the revegetation program in mining area.
