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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not 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.

|Population:||The global population is estimated to number c.100,000 individuals (Ferguson-Lees et al. 2001), while national population sizes have been estimated at c.10,000-100,000 breeding pairs in China and c.10,000-100,000 breeding pairs in Taiwan (Brazil 2009).|
Trend Justification: The population is suspected to be in decline owing to ongoing habitat destruction (Ferguson-Lees and Christie 2001).
|Current Population Trend:||Decreasing|
|Major Threat(s):||Deforestation in lowland India, the Philippines and Java represents the main threat to this species (Clark and Marks 2014).|
