Salvin’s Flame-bearer (Selasphorus ardens), John Gould The species of the genus Selasphorus, as pointed out by Mr. Elliot, are distinguished by the colour of their throats; and in the present species and S. platycercus the throat has been characterized by him as “dark amethystine-red.” 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."
