[Objectives] Asian OpenbillAnastomus oscitans is a newly recorded species in China, with the first sighting occurring in 2006. Since then, it has rapidly expanded its distribution to encompass over ten provinces and regions, including Yunnan, Guizhou, Sichuan and Gansu, etc., and has already become a regionally common species in some areas. Nevertheless, fundamental data regarding the population sources and movement patterns were still limited. [Methods] From November 2015 to July 2018, 11 storks were captured using the leg-harness method and equipped with satellite trackers in the Changqiao Hai Wetland of Mengzi, Yunnan Province, and the Caohai Wetland of Weining, Guizhou Province. The home ranges of onestorkwere calculated using the dynamic Brownian bridge model and its spatial movement patterns and habitat utilization were analyzed. [Results] Eight of the tracked storks died accidentally or did not leave the capture site, and only 3 exhibited longer-distance movements, of which one individual (ID no. 2647) successfully returned to its traditional breeding ground (Fig. 1). The stork (ID no. 2647) departed from Mengzi, Yunnan, China on August 29, 2018, migrating southwestward through Vietnam and Laos, and arrived in Chiang Rai, central Thailand on September 16, 2018, covering a distance of 775.06 km over 18 d. After a 95-day stay in Chiang Rai, it left on December 19, 2018, and moved eastward along the Mekong River bordering Laos and Thailand. It lost contact in Nghe An province, Vietnam, on March 6, 2019, after traveling 620.16 km over 79 d (Fig. 1). During its migration, the storkhad a total of 6 night roosting sites and 2 important stopover sites. Except for the last roosting site in farmland, all night roosting sites were in forests. It flew during the day and rested in forests at night. (Table 1). While in Chiang Rai, its total home range was 304.32 km2, with a core area of 0.97 km2, accounting for 3.2% of the total area (Fig. 2). The main habitat types used by the storks were cropland (79.72%) and forest (16.83%). [Conclusion] This study reveals the spatial connections between Asian Openbill populations in China and those in Thailand, Laos, and Vietnam, providing foundational data for further exploration of the distribution and dispersal patterns of this species.
