Taxonomy

Taxonomic note
Previously listed as Chlorostilbon maugaeus (del Hoyo and Collar 2014), but moved to current genus following a recent overhaul of all genera by NACC, based on McGuire et al. (2014), Stiles et al. (2017a, b) and others. Considered to be closely related to R. ricordii and R. swainsonii. Monotypic.

Population justification: The species is described as common, and it is frequently observed throughout its range (Stotz et al. 1996, eBird 2023). The population is estimated to number <20,000 pairs or <40,000 mature individuals (Nytch et al. 2015). The population is here tentatively placed in the band 30,000-39,999 mature individuals.

Trend justification: The species is widespread in a variety of habitats and appears largely unaffected by conversion and anthropogenic disturbance (Bündgen and Boesman 2020). Following hurricanes Irma and Maria in 2017, its occupancy increased (Lloyd et al. 2019). Its population is therefore assessed as stable, but may possibly even be increasing.
