"Fulicia. Coot. Bill and frontal plate much as in the Gallinultes. Body depressed; the under plumage thick and duck-like, to resist water. feet highly natatorial' toes, including the hinder, lobate, being furnished with large semicircular membranous flaps. The Coots are eminently aquatic birds, swimming with ease, by means of their lobate feet, like phalaropes and grebes; but this ability results from very slight modification of a structure shared by the Rails and Gallinules. There are about ten species, of both hemispheres, distinguished, among other characters, by the size and shape of the frontal shield. That, for instance, is of an exotic species, much larger than that of Fulica americana, and differently shaped. One species is remarkable for having the forehead singularly carunculate; the others closely resemble our common species." Elliott Coues, 1884

This curious winding is carried to the extreme in our Grus americanus, the whoopong crane, in which the wind-pipe is about as long as the whole bird, and about half of it - over two feet of it! - is coiled away in the breast-bone."

"Zenaidura carolinensis. Carolina Dove. Mourning Dove. Wild Dove. Upper parts, including middle tail-feathers, grayish-blue shaded with brownish-olive, the head and neck ochrey-brown overlaid with glaucous-blue, the sides of the neck glittering with golden and ruby iridescence; a violet-black spot under the ear-coverts. Under parts glaucous-purplish, changing gradually to ochraceous on the belly and crissum, to bluish on the sides and under the wings, to whitish on the chin; the purplish tint spreading up on the sides and front of the head to blend with the glaucous-blue. Black spots on some of the scapulars and wing-coverts, most of which are colored to correspond with the back, the larger ones being rather bluish-plumbeous. Lateral tail-feathers plumbeous-bluish, crossed with a black bar, the outer four on each side broadly ended with white. Bill black; angle of mouth carmine; iris brown; bare skin around eye livid bluish; feet lake-red, drying dull yellowish." Elliot Coues, 1884

"Dafila. Pin-tail Ducks. Tail (in adult male) narrow, cuneate, when fully developed nearly as long as wing, the 2 central feathers long-exserted, linear-acute: in female and young the tail merely tapering, with acute feathers; tail-feathers 16, including the long middle pair. Bill shorter than head, longer than tarsus, nearly parallel sided, widening a little to the end, the nail small, the narrow nostrils high up in basal third of bill. Feathers of cheeks sweeping in strongly convex outline along side of upper mandible, beyond those on side of lower mandible. Wing acute, the 1st and 2d primaries subequal and longest, rest rapidly graduated. Neck unusually long and slender, and form less "stocky" than that of most ducks. Sexes and young very unlike in color, even to the wing-markings, as well as in shape of tail. Bill and feet dark. Under parts white or whitish." Elliot Coues, 1884

AB, upper arm, brachium; BC, fore-arm, antibrachium; CD, whole hand or pinion, manus; composed of CE, hand proper or metacarpus, excepting d2; ED, or d2, d3, d4, fingers, digits, digiti, h, humerus; rd, radius; ul, ulna; sc, outer carpal, scapholunare or radiale; cu, inner carpal, cuneiforme or ulnare; these two composing wrist or carpus. mc, the compound hand-bone or metcarpus, composed of three metacarpal bones, bearing as many digits - the outer digit seated upon a protuberance at the head of the metacarpal, the other two situated at the end of the bone. d2, the outer or radial digit, commonly called the thumb or pollex, composed or two phalanges; d3, the middle digit, of two phalanges; d4, the inner or ulnar digit, of one phalanx d2 is the seat of the feathers of the bastard wing or alula. D to C (whole pinion), seat of the flight feathers called primaries; C to B (fore-arm), seat of the secondaries; at B and above it in direction of A, seat of tertiaries proper; below A, in direction of B, seat of scapularies (upon pteryla humeralis), often called tertiaries. The wing shown half-spread: complete extension would bring A B C D into a right line; in complete folding C goes to A, and D to B; all these motions nearly in the plane of the paper. The elbow-joint and wrist are such perfect hinges, that, in opening or closing the wing, C cannot sink below the paper, nor D fly up above the paper, as would otherwise be the effect of the pressure of the air upon the flight-feathers. Observe also rd and ul are two rods connecting B and C; the construction of their joining at B and C, and with each other, is such, that they can slide lengthwise a little upon each other. Now when the point C, revolving about B, approaches A in the arc of a circle, rd pushes on sc, while ul pulls back cu; the motion is transmitted to D, and makes this point approach B. conversely, in opening the wing, rd pulls back sc, and ul pushes on cu, making D recede from B. In other words, the angle A B C cannot be increased or diminished without similarly increasing or diminishing the angle B C D; so that no part of the wing can be opened or shut without automatically opening or shutting the rest..."
