Oasis Hummingbird (Rhodopis vesper)


Taxonomy

Taxonomy:

Ornismya vesper

Lesson

, 1829,

probably near Tarapacá, Chile (but possibly western Peru)

.

Closely related to Heliomaster, and sometimes included within that somewhat varied genus. Infraspecific variation very slight, and in need of revision; proposed race tertia (N Peru) tentatively included in nominate, although morphometrically inseparable from atacamensis; species may be better considered monotypic. Three subspecies provisionally recognized.

Subspecies and Distribution
  • R. v. koepckeae Berlioz, 1975 – NW Peru (Cerro Illescas, in SW Piura).
  • R. v. vesper (Lesson, 1829) – most of W Peru (S from Lambayeque) and extreme N Chile (Tarapacá).
  • R. v. atacamensis (Leybold, 1869) – N Chile (Atacama); probably this subspecies also farther south (Coquimbo).
