Constant’s Star-throat (Heliomaster Constanti), John Gould I have for a long time had examples of this bird in my collection with the name of Constanti attached thereto, but I have not as yet been able to find a description of it in any work; the “Echo du Monde Savante,” in which it is said to be described, being merely a kind of newspaper or journal of the day, and consequently seldom cared for after perusal, is now so rare as to be unprocurable. 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."
