Buff-breasted Humming-bird (Adelomyia cervina), John Gould This species of Adelomyia is easily recognized by the colour of the under surface of its body, which is buff with the flanks rufous; a further character is the brown-spotted throat. 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."
