Taxonomy

Taxonomic note

Chlorostilbon mellisugus (del Hoyo and Collar 2014) was previously split into C. mellisugus and C. melanorhynchus following SACC (2005), and before then lumped as C. mellisugus following Sibley and Monroe (1990, 1993).

Population justification: The global population size has not been quantified, but this species is described as 'common' (Stotz et al. 1996). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 2% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Therefore, as a precautionary measure, it is tentatively suspected that this loss of cover may have led to a decline of between 1-19% in the species' population size over the same time frame.
