White-throated Wedge-Bill (Schistes Albogularis), John Gould For the two specimens of this bird in my own collection, and which are the only examples I have seen, I am indebted to Professor Jameson of Quito, who collected them on the western side of Pichincha, at an elevation of 6000 feet above the level of the sea. 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."
