French: Colibri de Costa German: Veilchenkopfelfe Spanish: Colibrí de Costa

Taxonomy: Ornismya Costæ Bourcier, 1839, Magdalena Bay, Baja California, Mexico.
Genus often merged into Archilochus, and both have sometimes been subsumed into Selasphorus; however, in morphology, vocalizations and displays, members of present genus stand apart from the Selasphorus-Archilochus assemblage; alternatively, present genus sometimes merged into Mellisuga. Some authors would even place present species in the Archilochus superspecies. However, species is closely related to C. anna. Has hybridized with several other species of western North American hummingbirds, including C. anna, Selasphorus platycercus.. View all taxonomy...
