Simons’s Sabre-wing (Campylopterus phainopeplus), John Gould This beautiful Humming-bird was discovered by Mr. F. Simons, in the Sierra Nevada of Santa Marta, in 1879, and was met with by him at altitudes varying between 4000 and 15,000 feet above the sea-level. 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."
