Bearded Mountaineer (Oreonympha nobilis), John Gould Nobody who has examined a specimen of this Humming-bird has hesitated to designate it as one of the most striking of the whole family; and as for myself, I look upon it as one of the finest species of Humming-bird that I ever described. 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."
