2005年在中国青海湖暴发的H5N1型高致病性禽流感（HPAI）造成6000多只候鸟死亡，其中一半是斑头雁。了解这一物种的移动可能有助于监测高致病性病毒的爆发风险；为此，利用高分辨率GPS卫星遥测技术，对2007年和2008年青海湖29只斑头雁的运动规律进行了研究。我们描述了斑头雁在筑巢前、筑巢期和换羽期的运动和分布。有完整传播记录的21只斑头雁中，有3只在产卵期间迁移到其他地区，2只在产卵期间迁移到位于青海湖西北50 km处的江河湿地，1只迁移到位于青海湖西北220 km处的郭龙卡湖。我们在青海湖发现了7只雁试图筑巢。根据我们的繁殖状况判断规则，有4只雁成功尝试筑巢，2只雁在孵化后不久就失去了蛋（以下简称不成功的雁）。产卵期在青海湖的18只鹅中，有9只在换羽期留在青海湖，其中6只没有繁殖，2只繁殖成功，1只繁殖失败；9只（不繁殖5只，繁殖失败4只）离开青海湖去换羽。以库海、东盖措纳湖、阿拉克湖、扎陵陵湖和黄河源湿地为换羽地。在青海湖、郭龙卡湖、Kuhai湖、Donggeicuona湖和allake湖换羽的鹅也会在扎陵陵湖地区或黄河源湿地地区停留几天，然后再进行秋季迁徙。平均家庭范围和核心区域估计值在性别，年份以及育种者和非育种者之间没有显着差异。
The highly pathogenic avian influenza (HPAI) H5N1 outbreak at Qinghai Lake, China, in 2005 caused the death of over 6,000 migratory birds, half of which were Bar-headed Geese Anser indicus. Understanding the movements of this species may inform monitoring of outbreak risks for HPAI viruses; thus, we investigated the movement patterns of 29 Bar-headed Geese at Qinghai Lake, China during 2007 and 2008 by using high resolution GPS satellite telemetry. We described the movements and distribution of marked Bar-headed Geese during the pre-nesting, nesting, and moulting periods. Of 21 Bar-headed Geese with complete transmission records, 3 moved to other areas during the nesting period: 2 to Jianghe wetland (50 km northwest of Qinghai Lake) and 1 to Cuolongka Lake (220 km northwest of Qinghai Lake) during the nesting period. We identified nesting attempts of 7 of the marked geese at Qinghai Lake. Four completed successful nesting attempts according to our rules of judgment for the breeding status, and 2 geese lost broods soon after hatching (hereafter referred to as unsuccessful breeders). Of 18 geese present at Qinghai Lake during the nesting period, 9 (6 non-breeders, 2 successful breeders and 1 unsuccessful breeder) remained at Qinghai Lake during the moulting period; and 9 (5 non-breeders, 4 unsuccessful breeders) left Qinghai Lake for moulting. Kuhai Lake, Donggeicuona Lake, Alake Lake, Zhaling-Eling Lake area and Huangheyuan wetland area were used as moulting sites. Geese that moulted at Qinghai Lake, Cuolongka Lake, Kuhai Lake, Donggeicuona Lake and Alake Lake also moved to Zhaling-Eling Lake area or Huangheyuan wetland area and stayed there for several days prior to autumn migration. Mean home range and core area estimates did not differ significantly by sex, year and between breeders and non-breeders.
