Hummingbirds (Trochilidae)

Crimson Topaz (Topaza pella) - HBW 5, p. 563

French: Colibri topaze German: Rotnacken-Topaskolibri Spanish: Colibrí Topacio
Other common names: Topaz/Topaz-throated/King Hummingbird, Beautiful Topaz; Fiery/Inca Topaz (pyra)

Taxonomy: Trochilus Pella Linnaeus, 1758, Surinam.
Genus probably related to Eulampis and Anthracothorax, on basis of form of nest and display; has traditionally been placed close to Oreotrochilus. Race pyra often considered a separate species, but size and colour patterns indicate geographical variation only at subspecies level; some individuals of nominate race show glittering orange belly, thus resembling pyra. Race smaragdula has been proposed for birds of French Guiana, but not separable from nominate. Four subspecies currently recognized.

  • pella (Linnaeus, 1758) - S Venezuela (E Bolívar) and the Guianas to N Brazil (Amapá).
