Reeve’s Sapphire (Eucephala cæruleo-lavata), John Gould Among the numerous persons whose acquaintance and friendship I have had the pleasure of making during the progress of the present work, no one is more highly valued by me than Mr. Thomas Reeves of Rio de Janeiro, a gentleman who has at all times most liberally furnished me with whatever information he could acquire respecting the species inhabiting Brazil, and moreover enriched my collection with some species I could not have procured elsewhere; among which must be enumerated a very fine example of the bird figured on the annexed Plate. 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."
