Taxonomic note

Myioborus ornatus and M. chrysops (del Hoyo and Collar 2016) were previously lumped as M. ornatus following SACC (2005 & updates); Sibley & Monroe (1990, 1993); Stotz et al. (1996).

Population justification: The global population size has not been quantified, however is considered common through its range (Curson et al. 2020).

Trend justification: Tree cover loss in the last 10 years has equated to less than 2% within the species range (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). As such, the population is suspected to be stable.
