Grey-throated Hermit (Phæthornis griseogularis), John Gould There is every reason to believe that this species is spread over all the temperate regions of Columbia and Ecuador: I have frequently seen it in collections from Bogota, and I have had it sent direct from Quito by Professor Jameson, who gives 6000 feet as the altitude at which his specimen was procured; it is a beautiful representative in those regions of the P. eremita and P. pygmea of Brazil: it differs from them in its larger size, in the total absence of any crescentic black mark on the chest, and in having the throat clouded with dark grey instead of buff; the two central tail-feathers are also tipped with greyish white instead of buff, and the shafts of eremita and pygmæa are buff, while in the present species they are black. 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."
