Population justification: The global population size has not been quantified, but the species is described as locally common (del Hoyo et al. 2007, Allen 2020).
Trend justification: The population trend of this species is uncertain but it is suspected to be declining slowly in response to ongoing forest loss and degradation. Remote sensing data (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein) indicate that this is currently occurring at a rate of 2.5-3.0% over three generations. The impact of this on the species' population is unknown as it is known to be tolerant of some habitat degradation but is likely to be declining locally where there is total forest clearance. Much of the species' range lies outside protected areas, and habitat loss and degradation is suspected to continue.
