Rufous-breasted Sabre-wing (Campylopterus hyperythrus), John Gould We are indebted to the researches of the Chevalier Schomburgk for the discovery of this new species of Campylopterus, of which the single specimen he procured—an adult male—now graces the collection of the Museum at Berlin; and I would here beg to record my thanks to Dr. Lichtenstein, the Director of that Institution, for his kindness in permitting this rare bird to be removed to London, for the purpose of its being described and figured in the present work. 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."
