Family Hummingbirds (Trochilidae)

Least Concern

Loja Hummingbird (Amazilia alticola)

Following the taxonomy applied to HBW Alive, derived from the HBW and BirdLife International Illustrated Checklist of the Birds of the World, this taxon is now lumped within Amazilia Hummingbird (Amazilia amazilia).

Taxonomy

French: Ariane alticole German: Lojaamazilie Spanish: Amazilia de Loja
Taxonomy:

Amazilia alticola

Gould

, 1860,

Puna district, Peru; error = Loja, Ecuador

.

Forms a superspecies with A. amazilia and probably A. castaneiventris#R, of which formerly considered a race; differs in coloration, size (larger, except in tail length)#R, song repertoire and habitat requirements, and probably parapatric with A. amazilia dumerilii in Casanga Valley (C Loja), where no interbreeding yet observed. Morphological characters also suggest a reasonably close relationship with A. tzacatl#R. Some authorities maintain alticola as a subspecies of amazilia, but have recognized sufficient geographical variation within alticola to name another subspecies azuay (in R Jubones drainage in Azuay and immediately adjacent Loja), which should be regarded as conspecific with alticola, if the latter is split from amazilia, although the authors of azuay postulated that their new taxon might prove to be specifically distinct, while alticola would remain a subspecies of amazilia#R. Monotypic.

Distribution:

Andes of S Ecuador; doubtfully N Peru (the only evidence of its occurrence there being the type specimen, which is “said to be [from] the Puna district of Peru”)#R, although the type does appear to show some morphological characters suggestive of it being from the S end of the taxon’s range#R.
