Blue-tailed Mango (Lampornis viridis), John Gould It would seem that some confusion exists respecting the synonymy of this species, for a male specimen has been sent to me by M. Bourcier with the name of “Lampornis cyanurus, Audebert et Vieillot” attached to it, but I do not find that those authors have figured or described any species of this group under that appellation; on the other hand, it is unquestionably the bird described and figured by them and by Lesson under the name of Trochilus viridis. This illustration has been restored to its original vibrancy by enhancing colors and removing unwanted marks. A monograph of the Trochilidæ, or family of humming-birds was published between 1849 and 1887 by English ornithologist John Gould. This monumental work depicts and describes all the known species of hummingbirds at the time - comprising 418 lithographic plates and information on 537 species."
