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).
