Fawn-breasted Sabre-wing (Campylopterus rufus), John Gould The first notice of this species of Campylopterus occurs in the “Revue Zoologique” for 1840, where it was described by M. Lesson, under the above appellation, from specimens contributed by MM. Longuemare and Parzudaki; neither of those gentlemen, however, have given any account of its habits, nor do they even mention the locality the bird frequents. 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."
