Population justification: The global population is tentatively placed in the band 10,000-19,999 mature individuals (see Freile et al. 2019). The species is described as 'fairly common' (Stotz et al. 1996).
The species is known from two disjunct areas in El Oro, Loja and Tumbes, as well as in Manabí and Guayas. It is therefore assumed to form two subpopulations, but their respective sizes are unknown.

Trend justification: This species can inhabit dense regenerating scrub and secondary forest, indicating a moderate to high tolerance of habitat degradation and disturbance; however, it is absent from areas described as completely modified or forest patches frequented by livestock. The species has been assessed as being in decline at up to 30% over three generations (12.9 years) based on predictions of high rates of habitat loss in the future (Freile et al. 2010). However over recent years, forest loss has been low within the range (<3% over ten years since 2015; Global Forest Watch 2021); thus the projected rate of population decline over the past three generations may be highly precautionary. Assuming that forest loss is continuing at the same rate into the future, declines may not exceed 10% over the next three generations.
