Taxonomic note
Previously listed as Leucippus baeri (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. Monotypic.

Population justification: The global population size has not been quantified, but this species is described as fairly common to uncommon (Stotz et al. 1996, Schulenberg and Sedgwick 2021).

Trend justification:

The population trend has not been investigated. Tree cover within the range is very low (<2% over ten years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species is not forest-dependent but is often found in forest edge and arid scrub (Schulenberg and Sedgwick 2021); consequently, the current rate of tree cover loss may not be affecting the population. Therefore, in the absence of evidence for any declines or substantial threats, the population is suspected to be stable.
