James H. Partridge, Popular Science Monthly (1874)
“ We may admire the elegance of form and the quickness of motion of these birds, but the dazzling splendor of their plumage, resembling that of burnished metal or polished gems, changing with every change of position, has a charm for the dullest observer, and a fascination for the more sensitive. The wonderful change in color that takes place, according to the position of the light, from brilliant green, through the brightest golden tints, to intense velvety-black, or from black to emerald, or ruby, or crimson, or flame-color, reminds one of fairy-land, or the tales of the genii. ”
