Current view: Data table and detailed info

Taxonomy

Taxonomic note
Previously listed as Calliphlox mitchellii (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. Birds from Panama were initially misidentified as Chaetocercus heliodor. Monotypic.

Population justification: The global population is suspected to number fewer than 50,000 mature individuals (Partners in Flight 2022); therefore it is here placed in the band 20,000-49,999 mature individuals. The species is described as uncommon to locally common, but patchily distributed (Stotz et al. 1996, Schuchmann and Boesman 2020).

Trend justification: The population trend has not been investigated, but due to its dependence on forest, declines are suspected as a consequence of logging and habitat conversion. Tree cover within the range is lost at a rate of 3% over ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Therefore, population declines are here tentatively placed in the band 1-9% over ten years.
