Coppercrown (Elvira cupreiceps), John Gould This pretty little Humming-bird is a native of Costa Rica, where it would appear to have a restricted range, as only a limited number of specimens have reached us from that country. 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."
