Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996).
Trend justification: Populations of the species are suspected to be in decline due to ongoing habitat conversion and degradation in many places through its range (Hansen et al. 2013, Tracewski et al. 2016).
