In accord with AOS-SACC (Proposal 781), change the scientific name of Blue-headed Sapphire from Hylocharis grayi to Chrysuronia grayi, based on genetic evidence (McGuire et al. 2014) that Humboldt's Sapphire belongs to a disparate group of species for which the oldest available genus name is Chrysuronia (Stiles et al. 2017a, b).
