Middle-sized Hermit (Phaëthornis intermedius), John Gould The members of the genus Phaëthornis form a distinct and well-marked section of the Trochilidæ, and as the species are very numerous and very widely dispersed, they must play a considerable part in the economy of nature in the portions of the country they frequent; the present bird is an inhabitant of Brazil, to which country I believe it to be solely confined: from the notes of Mr. Reeves I learn that it is very common in all the virgin forests near Rio de Janeiro, and that its habits and economy closely resemble those of P. Eurynome and the other members of the genus. 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."
