Population justification: The global population size has not been quantified. Despite reports that the species may tolerate habitat degradation or even benefit from forest destruction (Willis 1972; Pulgarín-R. and Galvis 2020) it is now considered rare across its range (S. L. Hilty in litt. 1986).

Trend justification: Data on population trends are lacking, but declines are likely to be occurring as habitat destruction is ongoing within the species's range. Tree cover within the range has been lost at a rate of 7% over the past three generations (Global Forest Watch 2020), but habitat loss is likely exacerbated by additional degradation of forests, particularly in the understorey. Assuming that the rate of population decline is roughly equivalent to the rate of habitat loss, the species is tentatively assessed as declining at <20% over three generations.
