Population justification: This is a poorly known species and no population estimates are available. It is described a common (Remsen 2020).
Based on observational records (eBird 2020), the species is assumed to form at least two subpopulations.

Trend justification: Despite its tolerance of heavily degraded habitat, the species's distribution range is projected to contract with climate change, which will likely cause the population to decline. Modelling revealed that by the year 2080, the range will contract by 91-95%, depending on dispersal scenarios (Avalos and Hernández 2015). Nevertheless, this result needs to be treated with caution due to low sample size inflating the range contraction (Avalos and Hernández 2015). Furthermore, as the species is able to persist in converted habitats without any native vegetation (Remsen 2020), the rate of decline is here tentatively placed in the band 20-29% over ten years.
