Black-capped Humming-bird (Trochilus Polytmus), John Gould This species, the type, according to modern systematists, of the Linnean genus Trochilus, is perhaps one of the oldest and best-known members of the entire family, a description of it being included in nearly every general work on Natural History, as will be seen on reference to the synonyms given above; but although the bird itself has been so long known, nothing whatever had been recorded of its habits and economy until the appearance of the very interesting and valuable account published by P. H. Gosse, Esq. in his ‘‘ Birds of Jamaica,” and from which I shall take the liberty of transcribing the more important particulars. 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."
