Hummingbirds (Trochilidae)

Juan Fernandez Firecrown (Sephanoides fernandensis) - HBW 5, p. 635

French: Colibri robinson German: Juan-Fernandez-Kolibri Spanish: Colibrí de Juan Fernández
Other common names: Fernandez Firecrown

Taxonomy: Trochilus Fernandensis King, 1831, Juan Fernández Islands.
Genus seems to be closely related to a high-Andean lineage that includes Lesbia, Metallura, Oreonympha and Oreotrochilus. Sister-species relationship with S. sephaniodes supported by recent DNA studies; in past, phylogenetic affinities with other hummingbird species have been much disputed. In mid-19th century, pronounced sexual dimorphism caused the sexes to be classified as two different species within the same genus, until observations of mating and of the two morphotypes sharing the same nest revealed their true identities.

Race leyboldi of Alejandro Selkirk I (also Juan Fernández Is) is now extinct; originally considered a separate species. One extant subspecies recognized.
