This species has been uplisted to Near Threatened owing to a global population decline which is thought to approach the threshold for Vulnerable under the population size reduction criterion (A4abc). The species has an extremely large range and the overall population trend is very difficult to determine due to varying trends in different populations along different flyways. The population using the East Asian-Australasian Flyway is thought to be experiencing severe declines due to habitat loss in the Yellow Sea. Should new information arise providing clarification on the overall population trend it may warrant uplisting or downlisting.
