Cayenne Fairy (Heliothrix aurita), John Gould As this has been the longest known species of the present genus, I place it at the head of a group, for which the trivial name of Fairy will be very appropriate, since the elegance of their form and the peculiar chasteness of their colouring readily recall to memory the ideas of grace and beauty connected with those imaginary beings. 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."
