Abstract: An investigation was conducted to study the seasonal changes of bird communities in the natural and artificial habitats in Junggar Basin and near-foothills of Tianshan Mountains (Fukang, Xinjiang) from March 2009 to February 2010.Twelve line transects were installed in five habitats. A total of 147 species belonging to 17 orders, 38 families, and 90 genera were recorded. The amounts of summer visitors, residents, passersby, and winter visitors occupied 49.8%, 31.1%, 13.2%, and 5.9%, respectively, indicating that the study region was mainly inhabited by summer visitors. Of the total species number, residents occupied 13.9% and distributed in various kinds of habitat, suggesting that relative to other species, residents were more likely to become the dominant species in the region. Having the highest Shannon index (4.861) and species richness (106 species),lakes were the most important breeding grounds and stopovers for summer visitors. Based on the Morisita similarity index, all habitats were clustered into three typ
es, i.e., lake, desert, and farmland. Lake and desert habitats belonged to natural ones, in which, the seasonal turnover rate of birds peaked between spring and summer and declined then; while farmland, as an artificial habitat, attracted 68.5% of winter visitors, with the lowest turnover rate of birds between spring and summer (0.934) and the highest turnover rate of birds between summer and autumn (1.154). To preserve and plant Elaeagnus angustifolia forest belt would help to the increase of winter visitors’ diversity in the farmlands in Fukang, Xinjiang.
