Yellow-fronted Panoplites (Panoplites flavescens), John Gould In all probability the first example of this bird which reached this country was the one forwarded to me direct from Popayan in 1830. It was from this specimen that Mr. Loddiges took his description of the species, which appeared in the Proceedings of the Committee of Science and Correspondence of the Zoological Society for 1832. 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."
