Conservation

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Migration

Northern populations largely migratory. Southern populations resident. Birds from Siberia to North China and Japan winter mostly from South China to Thailand and South to Malaysia, and Sumatra (2 records, January and March); in Japan present mostly May-September/October, with very few noted in Central & South parts in winter; some short-distance movements recorded in Himalayan region.
