Abstract:From April to May and October to November 2011, the composition and diversity of avian community were surveyed in five downtown parks of Urumqi by the transect-line method. 47 bird species belonging to 9 orders, 23 families were recorded in total and the major species distribution pattern was the Palearctic type. Residents, summer breeders and winters respectively accounted for 44.68%, 34.04% and 10.64% of the recorded species. Mean density of birds in downtown parks was (11.27±4.3) ind./hm2 (mean ±S.D.), and the dominating species was Passer montanus, P. domesticus and Turdus merula. Bird density in spring was higher than that of autumn but the difference was not significant (F=0.002P=0.194). With diverse summer breeders as a vital composition, spring avian community showed higher species richness and diversity; autumn avian community present a relatively higher dominance index with a lower diversity because of the gathering of human-accompanying species, while the influence from winter species on avian community structure was slight. There was significant difference among species number and bird density of the five downtown parks, and the bird species was positively correlated with inner habitat diversity of the parks.
