In accord with AOS-NACC (Chesser et al. 2020b), change the scientific name of Golden-crowned Emerald from Chlorostilbon auriceps to Cynanthus auriceps (Stiles et al. 2017a, b), based on genetic evidence that the traditional genus Chlorostilbon is not monophyletic, and this species is embedded within Cynanthus (McGuire et al. 2014, Hernández-Baños et al. 2020).
