Migration route of the avian flu virus’ carrier Anser fabalis was studied for better understanding of the role migratory birds play in the spreading of avian influenza. During March and April in the nature reserve of Nanji Mountain, Poyang Lake, three healthy bean geese were armed with PTTs and tracked by satellite. One of them successfully returned data. The data was processed using Google Earth and MATLAB, and results are as follows. This bean goose migrated about 1,500 kilometers from Poyang Lake in Jiangxi Province to Qinhuangdao in Hebei Province via other four provinces including Anhui, Jiangsu, Shandong and Tianjin. Along the way there were five stopovers. The distances between two adjacent ones ranged from 20 kilometers to 700 kilometers (Fig.1). The rest duration of each stopover ranged from one day to fourteen days. Surface feature of about 68% stop sites were distinguished to be farmland (Fig.2). Average flight altitude was 15 meters and the maximum record was 407 meters (Fig.3).
