Blue-breast (Sternoclyta cyaneipectus), John Gould The merit of discovering this new species of Humming-bird is due to the late Mr. David Dyson, who formerly travelled in Honduras and Cumana, where, it is believed, this ardent lover of nature contracted the disease from which he never recovered, and which, to the regret of all who knew him, carried him off in the prime of life. 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."
