Avian Community Structure and Seasonal Dynamics in Different Habitats of Suzhou Industrial Park

The avian community in Suzhou Industrial Park was surveyed from May 2012 to April 2013. Four types of habitats were selected and 17 sample lines and 24 sample points were set up. About 130 bird species were recorded, belonging to 12 orders and 41 families,and Passeriformes were frequently observed. Among them,resident birds, summer migratory birds,winter migratory birds and transient migratory birds accounted for 26. 15%,25. 38%, 27. 69% and 20. 77% respectively. Avifauna mainly consisted of widely distributed species and Palaearctic species, but oriental species were also observed. The numbers of bird species were the highest in spring but the density of birds was the highest in winter. The number of bird species in wetlands was the highest and more evenly distributed. In contrast,the number of bird species in roads was the lowest and less unevenly distributed,and the dominant species were prominent with people passerine bird species. The consequences of cluster analysis showed that the environmental conditions were important factors in influencing the composition of birds.
