Sickle Bill (Eutoxeres Aquila), John Gould Two specimens are all that are known of this rare and singular Humming Bird; of these one is in the Loddigesian Collection, the other in my own. 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."
