Peruvian Racket-tail (Spathura Peruana), John Gould This fine species is at present so rare that few examples have come under my notice; of these, one brought from Peru by Dr. Tschudi is in the Museum at Neufchatel, and another, procured at Moyabamba, in the same country, by the late Mr. Mathews, graces the Loddigesian collection at Hackney. 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."
