Costa Rica Humming-bird (Eugenes spectabilis), John Gould Two species of the genus Eugenes are known—one, E. fulgens, being found in Texas and Mexico, and as far south as Guatemala, while the second species, E. spectabilis, replaces it in Costa Rica. 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."
