Population justification: The global population size has not been quantified, but this species is described fairly common (Silveira et al. 2023). In view of the high number of records within its large range (see eBird 2023), the population is unlikely to be small.

Trend justification: Precise data on the population trend are lacking, but slow declines are suspected to be occurring owing to ongoing habitat loss.
Tree cover within the range was lost at a rate of 7% over the past three generations (10.7 years; Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Even though the species is also found at borders and in tall secondary growth it remains dependent on forests (Hilty 2020, Silveira et al. 2023). Consequently, the rate of population decline may be equivalent, or even exceed, the rate of tree cover loss. To account for uncertainty, the rate of decline is here placed in the band 5-19% over three generations.
