White-sided Hill-star (Oreotrochilus leucopleurus), John Gould Hitherto this species has only been found in Chili, where it inhabits the sheltered valleys among the Andes, just below the line of perpetual congelation, and where it takes the place in those more southern regions of the Oreotrochilus Estellæ of Bolivia. 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."
