"Falco peregrinus. Peregrine Falcon. Duck Hawk. Great-footed Hawk. A medium-sized falcon, about as large as the foregoing, but known at a glance from any bird of N. 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." Elliot Coues, 1884

"Accipiter fuscus. Sharp-shinned Hawk. "Pigeon" Hawk. Above, dark plumbeous, slate-color, or bluish-gray, somewhat more fuscous on the wings and tail than on the body, the feathers of the hind-head with fleecy white bases, the scapulars with concealed white spots. Tail crossed by about 4 blackish bars, the first under the coverts, the last subterminal and broadest; extreme tips of the feathers white. Primaries also marked with blackish bars or spots, and whitening at their bases, in bars or indents of the inner webs. Under parts barred crosswise with rufous on a white ground, the bars on some parts cordate and connected along the shafts of the feathers, which are blackish; ear-coverts rufous; rufous mostly or entirely wanting on the cheeks, throat, and crissum, which are more or less finely pencilled with the black shafts of the feathers; crissum, however, often pure white. Axillars barred like other under parts; lining of wings white, with dusky spots." Elliot Coues, 1884

"Ceryle alcyon. Belted Kingfisher. Upper parts, broad pectoral bar, and sides under the wings, dull blue with fine black shaft lines. Lower eyelid, spot before eye, a cervical collar and under parts except as said, pure white; the female with chestnut belly-band and the sides of the same color. Quills and tail-feathers black, speckled, blotched or barred on the inner webs with white; outer webs of the secondaries and tail feathers like the back; wing-coverts frequently sprinkled with white. Bill black, pale at base below. Feet dark; tibiae naked below. A long, thin, pointed occipital crest; plumage compact and oily to resist water, into which the birds constantly plunge after their finny prey." Elliot Coues, 1884
