Hummingbirds (Trochilidae)

Blue-tailed Hummingbird (Saucerottia cyanura) - HBW 5, p. 604

French: Ariane à queue bleue German: Blauschwanzamazilie Spanish: Amazilia Coliazul

Taxonomy: Amazilia cyanura Gould, 1859, Realejo, Nicaragua.
Genus usually merged into Amazilia. Forms a superspecies with S. beryllina; reports of hybridization in a small zone of sympatry in Guatemala and El Salvador seem to be unproven, and may be erroneously based on variable tail coloration of that species. In recent literature only two races have been recognized, with impatiens from Costa Rica ignored, perhaps because only two specimens exist; however, morphological characters indicate that it should be considered valid. Races show highly disjunct distribution. Three subspecies recognized.

Subspecies and Distribution:

  • guatemalae Dearborn, 1907 - SE Mexico (SE Chiapas) to S Guatemala.
  • cyanura (Gould, 1859) - S Honduras, E El Salvador and NW Nicaragua.
  • impatiens Bangs, 1906 - NW & C Costa Rica.
