Chestnut-bellied Amazili (Amazilia castaneiventris), John Gould This unique bird has been in my collection for a long time; it was sent to me, with a number of other Humming-Birds, by Mr. Mark, Her Britannic Majesty’s Consul at Bogota, without any information as to where it was collected. 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."
