Population justification: The global population is suspected to number 500,000-4,999,999 mature individuals (Partners in Flight 2022). The species is described as 'uncommon' (Stotz et al. 1996).

Trend justification: The population trend is difficult to determine, as the degradation of primary forests may benefit populations inhabiting secondary growth and dry woodland, while it may threaten populations in mangroves (Robbins 2020). Tree cover loss is low within the range (4% over ten years; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein); consequently, this may not currently be affecting the overall population. Tentatively, the population is assessed as stable.
