Home ranges could reflect the spatial requirements of animals at the individual level. Home range research is important for species conservation and understanding the relationship between animals and the environment. [Methods] During the winters of 2017, 2018 and 2019, seven Bar-headed Geese (Anser indicus) were tracked by satellite tracking in the Napahai Wetland, Yunnan Province. The dynamic Brown Bridge model was used to construct the wintering home range of Bar-headed Geese, and the impact of water area change on the home range of Bar-headed Geese were analyzed by combining remote sensing technology. The individual monthly home range differences were analyzed using the non-parametric Kruskal-Wallis test. [Results] (1) The total home range of the tracked Bar-headed Geese was 28.49 km2, of which 54.7% located in the nature reserve; the total core area was 4.17 km2, of which 55.3% located in the nature reserve, and the rest mainly distributed in the grass or swamps on the periphery of the nature reserve and the corner area of Shangri-La Airport and the urban area (Fig. 2); (2) The average area of home range and core area of Bar-headed Geese during the wintering period were 5.98 ± 0.63 km2 and 0.55 ± 0.12 km2 (n = 8, data for one individual in wintering season of 2017, six individuals in wintering season of 2018 and one individual in wintering season of 2019). The core area accounted for only 9.2% of the home range (Table 1); (3) The home range and core area of different Bar-headed Geese varied greatly, with the maximum home range of 8.22 km2 and the minimum of only 3.38 km2, and the maximum core area of 1.21 km2 and the minimum of 0.12 km2 (Table 1); (4) In 2018, the water areas of the Napahai were 8.54 km2 in February, 6.36 km2 in March and 5.00 km2 in April, showing a trend of monthly decrease. There was a monthly trend of decreasing utilization of water by the Bar-headed Geese, with a mean utilization of water of 59.95% ± 12.9% (n = 6), 55.12% ± 16.4% (n = 6) and 23.67% ± 12.3% (n = 3) in February, March and April, respectively. The alterations in the water area of the Napahai wetland had a significant impact on the home range of the Bar-headed Geese. The marsh and meadow expanded as the water area withdrew from south to north, and the home range of the Bar-headed Goose grew broader and moved in the direction of the retreating water area. (Fig. 3); (5) As to the Bar-headed Geese of Id2639, which was tracked both in wintering seasons of 2018 and 2019, there was considerable variations of its home range area and core area. Its home range in 2018 was 5.98 km2, smaller than that in 2019 (8.22 km2), and its core area in 2018 was 0.61 km2, also smaller than that in 2019 (1.21 km2). The overlap index (IO) of the home ranges between two wintering seasons was only 0.31 (Fig. 4). [Conclusion] As the Bar-head Goose is a major carrier and transmitter of H5N1 highly pathogenic avian influenza, we suggest that the nature reserve should increase the management scope and concentrate on the local villages (Kaisong, Nagong and Darijue in Jiantang Town, Shangri-La City, Diqing Prefecture, Yunnan Province.) that overlapping with the home range of the Bar-headed Geese. To prevent the spread of avian influenza, domestic pigs should be raised in captivity in winter, and not be allowed to forage together with Bar-headed Geese.
