"Circus cyaneus hudsonius. American Marsh Hawk, Harrier. Blue hawk. Adult Male: In perfect plumage pale pearly-bluish, or bluish-ash, above, with the upper tail-coverts entirely pure white; but most specimens have a dusky wash obscuring the bluish, and retain traces of brown or rufous. Five outer primaries mostly blackish, all of them and the secondaries with large white basal areas on inner webs; tail-feathers banded with 5 or 6 obscure dusky bars, the terminal one strongest and most distinct, and marbled with white toward their bases. The bluish cast invades the fore under parts, the rest of which are white, with sparse drop-shaped rufous spots; lining of wings white. From this blue-and-white state the bird is found grading by degrees into the very different plumage of the female and young: Above, dark umber-brown, everywhere more or less varied with reddish-brown or yellowish-brown, the upper tail-coverts, however, white, forming a very conspicuous mark; under parts a variable shade of brownish-yellow, or ochraceous, streaked with umber-brown, at least on breast and sides; tail crossed with 6-7 blackish bars."

The Axial Skeleton of a bird or any vertebrated animal, that is, one having a back-bone, exhibits in cross-section two rings or hoops, one above and the other below a central point, like the upper and lower loops of a figure 8. The upper ring is the neural arch, so called because such cylinder encloses a section of the cerebro-spinal axis, or principal nervous system of a vertebrate (brain and spinal cord, whence arise all the nerves of the body, excepting those of the sympathetic nervous system). The lower ring is the haema arch, which similarly contains a section of the principal blood vessals and viscera.

"Astur atricapillus. American Goshawk. Blue Hen Hawk (adult). Chicken Hawk (young). Adult: Above, dark bluish-slate color, each feather black-shafted; top of head blackish, conspicuously different from other upper parts, the feathers there with fleecy white bases; a long white superciliary or rather post-ocular stripe; auriculars blackish. Ground color of under parts, including lining of wings, white, closely barred or vermiculated in narrow zigzag lines with slaty-brown, except on throat and crissum, and everywhere sharply pencilled with blackish shaft-lines, one on each feather. The barring is largest and most regular on the belly, flanks, and tibiae, but is for the most part much dissipated in a fine mottling. It varies greatly in coarseness in different specimens, some of which approach A. palumbarius in this respect. Tail like back, banded with four or five blackish bars, the terminal one much the broadest. Bill dark bluish; iris yellowish; feet yellow, claws black." Elliot Coues, 1884

"Falco mexicanus. American Lanner Falcon. Prairie Flacon. A medium-sized species, distinguished from any gyrfalcon by the smaller size, different feathering of the tarsus etc., from the duck hawk by the general much lighter color, which is dull brownish above instead of dark slate, etc. Adult: Upper parts brownish-drab, each feather with a paler border of brown, grayish, or whitish; the top of the head more uniform, the occiput and nape showing more whitish. Under parts white, everywhere excepting on the throat marked with firm spots of dark brown, most linear on the breast, then more broadly oval on the belly, enlarging and tending to merge into bars on the flanks, very sparse or obsolete on the crissum, on the maxiliary region forming a broad firm moustache; these marking corresponding with the ground color of the upper parts. Primaries ashy-brown, with narrow but firm pale edging of outer webs and ends, the inner webs regularly marked with white in form of barred indents or circumscribed spots, most numerous and regular on the outer primaries; the white tinged with fulvous, next to the shafts; the outer web of the first primary either plain, or with whitish indents as in F. lanarius; outer webs of secondaries more or less marked with fulvous; axillars plain dark brown; lining of wings otherwise white, spotted with dark brown. Tail pale brownish-gray, nearly uniform, but with white tip, and more or less distinct barring or indenting with whitish, especially on the lateral feathers, producing a pattern not unlike that of the primaries. Bill mostly dark bluish horn-color, but its base, and much of under mandible, yellow; feet yellow." Elliot Coues, 1884

"Falcons. Bill furnished with a sharp tooth and notch near the end of the cutting edge of the upper mandible (sometimes two such teeth), and the end of under mandible truncated, with notch near the tip. Nostrils circular, high in the cere, with a prominent central tubercle. Inter-nasal septum extensively ossified. Palate with a median keel anteriorly. Superciliary shied prominent, in one large piece. Shoulder-joint strengthened by union of scapular process of the coracoid with the clavicle as in Micrastur, Herpetothers, and the Polyborinae alone of Flaconidae.

Am. by the slaty-plumbeous or dark bluish-ash of the upper parts, the black "moustache," and other marks, taken with its particular size and shape. Wings stiff, long, thin, pointed by the 2d quill, supported nearly to its tip by 1st and 3d; 1st quill alone abruptly emarginate on inner web, this about 2 inches from its tip; none cut on outer webs. Tomium of upper mandible strongly toothed, of under mandible deeply notched. Tarsus feathered but a little way down in front, otherwise entirely reticulate; toes very long, giving great grasp to the talons. Adult: Above rich dark bluish-ash or slate-color, very variable, sometimes quite slaty-blackish, again much lighter bluish-slate; the tint pretty uniform, whatever it may be, over all the upper parts, but all the feathers with somewhat paler edges, and the larger ones for the most part obscurely barred with lighter and darker hues. Under parts at large varying from nearly pure white to a peculiar muddy buff color of different degrees of intensity; the throat and breast usually free from markings (or only with a few sharp shaft pencillings), and this white or light color mounting on the auriculars, so that it partly isolates a blackish moustache from the blackish of the side of the head; the under parts, except as said, and including the under wing- and tail-coverts closely and regularly barred, or less closely and more irregularly spotted, with blackish; the bars best pronounced on the flanks, tibiae, and crissum, other parts tending to spotting, which may extend forward to invade the breast (this is the rule in European birds, the exception, though not a rare one, in American birds). Tail and its upper coverts regularly and closely barred with blackish and ashy-gray, the interspacing best marked on the inner webs, and all the feathers narrowly tipped with white or whitish."

Conspicuous black maxillary and auricular patches which, with three others around the nape, make seven places in all, usually evident, but some of them often obscure or wanting. Back cinnamon-rufous, or chestnut, like the crown-patch, in the male with a few black spots or none, in the female with numerous black bars. Wing-coverts of the male fine ashy-blue, like the crown, with or without black spots; of the female cinnamon-rufous and black barred, like the back.

Upper surface of tail rich chestnut, with white tip and usually a black subterminal zone, with or without other narrower and more or less imperfect black bars; sometimes barred throughout. From below, the tail appears pearly whitish with a reddish tinge, wither quite uniform, or barred throughout with the whitish and blackish. In general, it is the female with the most barred or completely barred tail, the male with the uniform tail, only subterminally once-zoned. Upper parts blackish-brown, with a thoroughly indeterminate amount of light variegation, gray, fulvous, and whitish; feathers of hind head and nape with cottony white bases, showing when disturbed; those of hind neck usually with fulvous edging; of scapular region showing most variegation with tawny or whitish, or both, the scapulars and adjoining feathers being largely barred, and only blackish on their exposed portions; upper tail-coverts showing much tawny and white. Ground color of under parts white, more or less buff-toned, the dark color of the upper parts reaching nearly or quite around the throat, the flanks and lower belly heavily marked with dark brown or blackish, but a large pectoral area, with the tibiae and crissum, mostly free from markings, as a rule; but no description will cover the latitude of coloration.

"Archibuteo lagopus sancti-johannis. American Rough-legged Buzzard. "Black Hawk" Adult: Too variable in plumage to be concisely described. In general, the whole plumage with dark brown or blackish and light brown, gray, or whitish, the lighter colors edging or barring the individual feathers; tendency to excess of the whitish on the head, and to the formation of a dark abdominal zone or area which may or may not include the tibiae; usually a blackish anteorbital and maxillary area. Lining of wings extensively blackish. Tail usually white from the base for some distance, then with dark and light barring. The inner webs of the flight-feathers white from the base, usually with little if any of the dark barring so prevalent among buteonine hawks. From such a light and variegated plumage as this, the bird varies to more or less nearly uniform blackish, in which case the tail is usually barred several times with white. Our lighted-colored birds are not fairly separable from the normal European A. Lagopus; but our birds average darker, and their frequent melanism does not appear to befall the European stock. But in any plumage the rough-leg is known at a glance from any Buteo by the feathered shanks; while the peculiar coloration of A. ferrugineus i highly distinctive of the latter." Elliot Coues, 1884

The mesites (Mesitornithidae) are a family of birds of uncertain affinities. They are smallish, near flightless birds endemic to Madagascar. Generally brownish with paler undersides, they are of somewhat pheasant-like appearance and were initially placed with the Galliformes. Most commonly, they are placed in the Gruiformes (cranes, rails and allies), but this has been disputed in more recent times. They are the only family with more than two species in which every species is threatened; all three are listed as vulnerable and are expected to decline greatly in the next 20 years.

Long feathers of the sides under the wings matching the upper wing-coverts nearly; under wing-coverts and axillaries pure white, not marked; flanks with bars or U-spots of dark brown. Legs grayish-white, unmarked. Quills of the wings fuscous; outer webs of the secondaries with equidistant, squarish, white or tawny spots, the secondaries tipped and imperfectly twice or thrice barred with white, gradually becoming sprinkled with the varied colors of the back, so that the innermost of them are almost precisely like the greater coverts.
