Black-eared Humming-bird (Heliopædica melanotis), John Gould Although Prince Charles Bonaparte and all recent writers consider the present bird and the Trochilus leucotis to be identical, and have made the two names synonymous, I have very great doubt as to the accuracy of this opinion, as Vieillot makes no mention of the splendid blue colouring of the crown, and moreover states that his bird is from Brazil, while the native countries of the one here figured are Guatemala and Mexico. 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."
