Hummingbirds (Trochilidae)
Glittering-throated Emerald (Polyerata fimbriata) - HBW 5, p. 601
French: Ariane de Linné
German: Glitzerkehlamazilie
Spanish: Amazilia Listada
Taxonomy: Trochilus fimbriatus J. F. Gmelin, 1788, Cayenne.
Genus sometimes lumped into Agyrtria; these two usually merged into Amazilia. Forms a superspecies with P. lactea. Races fluviatilis, nigricauda and tephrocephala were all previously treated as distinct species. Several proposed races are invalid due to similar morphology and range overlap with adjacent forms: obscuricauda has proved to be identical to elegantissima; maculicauda and alia are inseparable from nominate race. In Táchira, Venezuela, the very local “Amazilia distans” is most probably of hybrid .. View all taxonomy...

In Táchira, Venezuela, the very local “Amazilia distans” is most probably of hybrid origin, present species x Hylocharis cyanus. “P. cyaneotincta”, known only from two skins of uncertain origin, has been suggested to be aberrant form of present species, but this seems unlikely; in plumage pattern more similar to P. amabilis. Seven subspecies currently recognized.
