Little Flame-bearer (Selasphorus Scintilla), John Gould This very lovely little species, to which I have given the specific name of scintilla, at first sight suggests the idea that it is merely a miniature representative of the Selasphorus rufus; on inspection, however, it will be found to differ not only in size, but in many other particulars, especially in the form and markings of the tail, the general contour of which is less rounded, each feather less acutely pointed; and the outer webs of the lateral ones and the centres of the remainder broadly streaked, instead of being merely striated, with black near the point; the upper surface too of all the specimens I have examined is golden-green, without a trace of the buff colour so conspicuous in S. rufus. 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."
