Population justification: The global population is suspected to number fewer than 50,000 mature individuals (Partners in Flight 2020); thus it is here placed in the band 20,000-49,999 mature individuals, but these values require confirmation. The species is described as fairly common to common and locally numerous (Stotz et al. 1996, Collar 2020).

Observational records (per eBird 2021) suggest that the species forms three separate subpopulations.

Trend justification: The species is suspected to be in decline (Partners in Flight 2020). Tree cover loss within the range is low (up to 2% over ten years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein) and large parts of the range are currently not under threat; therefore declines are unlikely to exceed 10% over ten years.
