Methods The bird's community structure in winter was investigated on Badaling area from 2005 to 2006 using the line transect method,the species,number,habitat and aggregation of bird were taken record to analyze the potential source of infection,mode of transmission and the susceptive birds. Results Total 39 species of birds (6 orders and 19 families) were found during the study periods. Waterfowls weren't found in this area. Most of the aggregative birds were habitat in brushwood,however,60% birds were not aggregative.
