Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 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 size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but the species is described as often common (del Hoyo et al. 2005), while the population in China has been estimated at c.10,000-100,000 breeding pairs (Brazil 2009). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 11.2% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). However, as it is relatively adaptable, the species' range and population size is thought to be increasing (del Hoyo et al. 2005).
