Ruby and Topaz (Chrysolampis moschitus), John Gould If any one species of this extensive family of birds be better known than another, it is undoubtedly the Ruby and Topaz Humming Bird here represented, for it is not only one of those earliest discovered, but its beauty is of such a character as at once to fix the attention of every observer. 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."
