Population justification: The global population size has not been quantified, but the species is described as common and having flexible habitat requirements (Rasmussen and Anderton 2005). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 1.5% within its mapped range over the past three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The population trend is therefore considered stable.
