With the text page explaining "The discovery of this splendid species is due to our great navigator Captain Cook . Captain Cook made the following observations, when mentioning this beautiful species. "There are also Humming-Birds, which yet seem to differ from the numerous sorts of this delicate animal already known, unless they be a mere variety of the Trochilus colubris of Linnaeus. These, perhaps, inhabit more to the southward, and spread northward as the season advances; because we saw none at first, though, near the time of our departure the natives brought them to the ships in great numbers" (p72). Handcolored engraving by W.H. Lizars from a drawing by an unknown artist for Sir William Jardine's "Naturalist's Library, The Natural History of Humming-birds".
