Population justification: The global population size has not been quantified, but the species is described as common to fairly common within its small range (del Hoyo et al. 2007, Eaton et al. 2021).
Trend justification: Data on population trends are lacking, but moderate declines are suspected on the basis of ongoing forest loss. Remote sensing data (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein) indicate that in the ten years to 2022, forest cover in the species' range reduced by 5-6%. This species is considered highly forest dependent (Haryoko et al. 2021), and these forest losses are suspected of having caused a broadly similar (1-9%) reduction in the species' population size. Forest loss appears to be ongoing and population declines are therefore suspected to continue at the same rate into the future.
