Understanding animal migration route and activity rhythm are of great significance to protection of migratory birds. From February to March 2019, 20 Bean geese (Anser fabalis) in Lake Poyang were tracked with satellite collars. We analyzed their migration routes and activity rhythm during their migration period based on the data collected from these GPS collars. The results showed that Bean goose started migration most early in 12, March, and some started in 25, April. The Bean geese were tracked for 60.5±15.6 days (n=19), with migration distance 1349.5±1004.9 km (n=18) and stop site number 6±3 (n=18). The spring migration routes of Bean goose formed two lines:the east line and the middle line. The east line passed through Anhui, Jiangsu, Shandong, Liaoning, Jilin, and Heilongjiang Provinces, and arrived at Russia. The middle line passed through Hubei, Anhui, Henan, Hebei, Inner Mongolia Provinces, and arrived at Mongolia. Bean goose didn't stay for a long time in stopover sites between 30°-40°N latitude, but stopped for a significant longer time (12.7±7.2 days) between 40°-50°N latitude. Northeast China Plain and the eastern Inner Mongolia plateau are important stopover sites for them. Bean goose is a diurnal animal; its activity level in day is significantly higher than that at night. In the pre-migration period, the activity peaks at 8:00-9:00 and 18:00-19:00, while the activity peaks occurred in 7:00-8:00 and 18:00-19:00 during migration. There was significant variation of average migration distance in different environment temperatures (n=8827,df=9,P=0.000), and its maximum migration distance (4.9±14.4 km/h) occurred in 0-5℃.
