(syn. Oreotrochilus Ϯ Andean Hillstar O. estella) Prof. Alcide Dessalines d’Orbigny (1802-1857) French ornithologist and author; "Alcidius, Nov. Gen. ... TYPE: O. estellae, d'Orbigny. ... I have made a new genus with this species and the four following ones, because they are quite distinct, in generical forms, especially in the form of the tail, and in the metallic colouring of head and throat, from the two well-known species, O. pichincha and O. chimborazo. For these two last species, I have retained the generic name of Oreotrochilus, Gould considering that it was more proper to make a new genus, in honour of D'Orbigny, with the species discovered by this eminent Naturalist. I hope that all my scientific colleagues will agree with me in this, and will adopt it" (Boucard 1895).
