Green-tailed Sylph (Cynanthus smaragdicaudus), John Gould In general structure this beautiful species is most closely allied to the Blue-tailed Sylph (Cynanthus cyanurus) 5 it is, however, of rather smaller size, and may at all times be distinguished by its resplendent metallic green tail: unfortunately nothing whatever is known of its habits and economy, but they are doubtless as similar to those of its ally, as the two birds are in form and structure. 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."
