Hummingbirds (Trochilidae)

Ecuadorian Hillstar (Oreotrochilus chimborazo) - HBW 5, p. 623

French: Colibri du Chimborazo German: Ecuador-Andenkolibri Spanish: Colibrí del Chimborazo
Other common names: Violet-hooded Hillstar; Chimborazo Hillstar (chimborazo)

Taxonomy: Trochilus Chimborazo DeLattre and Bourcier, 1846, Mount Chimborazo, Ecuador.
Forms a superspecies with O. estella, O. stolzmanni and O. leucopleurus, and all four have been considered conspecific, but separated largely on morphological grounds. Race soederstroemi is sometimes thought to be an intergrade of jamesonii and nominate, but it is apparently isolated geographically from both of them. Three subspecies currently recognized.

Subspecies and Distribution:

  • jamesonii Jardine, 1849 - mountains of extreme S Colombia and N Ecuador (Cotacachi, Pichincha, Iliniza, Antisana, Cotopaxi).
  • soederstroemi Lönnberg & Rendahl, 1922 - C Ecuador (Mt Quilotoa).
  • chimborazo (DeLattre & Bourcier, 1846) - C Ecuador (Mt Chimborazo, possibly also Azuay).
