In his outward aspect the male bird bears upon him many marks of dignity which distinguish him from the female: such is the crest which serves him as the emblem of monarchy,—a crown; the blackish and loose skin which in folds covers the head, and gathering up behind, after the manner of curls or frizzled hair, resembles a wig; and the white of the wings, when the bird stands erect, gives his shoulders the appearance of being covered with a mantle or cloak.—See the excellent Memoir of Messrs. Humboldt and Bonpland on the Natural History of the Condor, printed in Paris in the year 1807. Santiago Cardenas, better known by the name of Santiago _el Volador_, or Flier, for many years watched the flight of the condor, with the intention of imitating him; and he left a quarto volume written on this subject, which I have deposited in the library of the College of San Fernando. In this work he describes three different kinds of condor. 1. Moromoro with ruff (golilla) and mantle of the colour of ashes.—It has of “_embregadura_,” or length, from the point of one wing to that of the other, from thirteen to fifteen feet. This, of all the condors, is the strongest; and he takes ostentatious delight in combating against the wind, and balancing himself on extended but flutterless wing in the most imposing and majestic manner. It has been said of the moromoro, that, seizing the newly-born lamb, he throws it over his shoulder, where he keeps it steadily fixed; and, having thus secured his prey, rises on the wing, and betakes himself to flight.[57] 2. Condor of ruff and mantle of the colour of clear coffee.—He has of _embregadura_ from eleven to thirteen feet, and he is swift and daring. 3. Condor with white mantle and ruff.—He has expanse of wing, or _embregadura_, from nine to eleven feet; and this is the most abundant and beautiful species. The condor inhabits the steep rocks of the Andes; and, according to the observations of Santiago, he makes every day two journeys to the coast in search of food, which shows his prodigious velocity. In our dissection of this bird, we met with no air-vessel which could maintain a communication between the lungs and the spongy substance of the clavicles, nor any communication between the crop and windpipe. The internal cavity of the chest is lined by a fine and transparent membrane or pleura, which forms various little cells; the lungs descend as low as the abdomen, and adhere, at their posterior extremity, to the spine and ribs, which have perforations at the points of adhesion, communicating with the interior of their spongy body. The texture of the lungs is porous, so that, as soon as they are blown into and inflated through the windpipe, they freely supply with air all the recesses or concealed crevices, great and small, that are about them; and they also fill with air the cavities of the ribs and sternum.
