Red-booted Racket-tail (Spathura rufocaligata), John Gould This new Humming-bird was procured in Bolivia by Mr. Bridges, who informed me that he found the species rather numerous at Sandillani in the Yungas of La Paz, but had no opportunity of making himself acquainted with its habits, for a knowledge of which, therefore, we must await the researches of some future traveller: there is little doubt, however, that they will prove to be very similar to those of its near allies, the Spathura Underwoodi and S. Peruana. 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."
