Summer bird diversity of the major wetlands in Fuyang City

In order to acquire the knowledge of bird diversity in Fuyang City,we investigated 4 major wetlands during July-September 2011.There were 43 species of waterbirds belonging to 11 orders and 25 families.Passerine constituted the majority of wetlands birds,accounting for 44.1%.Oriental,Palaearctic and Cosmopolitan species made up 39.5%,34.8% and 25.6% of the total number of breeding birds respectively.Waterfowl accounted for 47.8% of wetland bird species.Dominant species in the wetlands were Hirundo rustica,Delichon dasypus,and Sturnus cineraceus.Among the 4 wetlands,Balihe Provincial Nature Reserve ranked the first in both bird species(N=30) and diversity index(H=2.49),and the similarity coefficient among these wetlands was high.Bird diversity index and species richness had a significant relation with the area of wetlands(the former r=0.985,P=0.015;the latter r=0.974,P=0.026).From the view of bird diversity protection,the construction and management of wetland reserve and park should follow the trend of wetland maintaining and vegetation complexity increasing.
