Bolivian Rainbow (Diphlogæna Aurora), John Gould The beautiful bird to which I have given the name of Diphlogena Iris, and the one represented in the accompanying plate, were both collected by M. Warszewicz; and two finer or more interesting species are scarcely to be found among the Trochilidæ. 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."
