“The beak of the Condor is straight at the base, but the upper mandible becomes arched toward the point, and terminates in a strong and well curved hook. The basal half is of an ash brown, and the remaining portion, toward the point, is nearly white. The head and neck are bare of feathers, and covered with hard, wrinkled, dusky reddish skin, on which are scattered some short brown or blackish hairs. On the top of the head, which is much flattened above, and extending some distance along the beak, is attached an oblong firm caruncle or comb, covered by a continuation of the skin which invests the head. This organ is peculiar to the male. It is connected to the beak only in its anterior part, and is separated from it at the base in such a manner as to allow a free passage of the air to the large oval nostrils, which are situated beneath it at that part. Beyond the eyes, which are somewhat elongated, and not sunk beneath the general surface of the head, the skin of the neck is, as it were, gathered into a series of descending folds, extending obliquely from the back of the head over the temples, to the under side of the neck, and there connected anteriorly with a lax membrane or wattle, capable of being dilated at pleasure, like that of the common turkey. The neck is marked by numerous deep parallel folds, produced by the habit of retracting the head, in which the bird indulges when at rest. In this position scarcely any part of the neck is visible. “Round the lower part of the neck both sexes, the female as well as the male, are furnished with a broad white ruff of downy feathers, which forms the line of separation between the naked skin above and the true feathers covering the body below it. All the other feathers, with the exception of the wing coverts, and the secondary quill feathers, are of a bright black, generally mingled with a grayish tinge of greater or less intensity. In the female the wing coverts are blackish gray; but the males have their points, and frequently as much as half their length, white. The wings of the latter are consequently distinguished from those of the female by their large white patches. The secondary quill feathers of both sexes are white on the outer side. The tail is short and wedge shaped. The legs are excessively thick and powerful, and are colored of a blueish gray, intermingled with whitish streaks. Their elongated toes are united at the base by a loose but very apparent membrane, and are terminated by long black talons of considerable thickness, but very little curved. The hinder toe is shorter than the rest, and its talon, although more distinctly curved, is equally wanting in strength, a deficiency which renders the foot much less powerful as an organ of prehension than that of any other of the large birds of the raptorial order.”
