Adolph’s Hermit (Phaëthornis Adolphi), John Gould The fact of Central America having a fauna peculiarly its own has been frequently mentioned in the pages of the present work; and so decidedly is this the case, that while it comprises certain species and even genera which do not exist elsewhere, the species there found are generally representatives of others inhabiting South America proper, or that portion of the continent to the southward of Panama. 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."
