"Another small family, characterized by the extreme length of the slender legs, and the extreme slenderness of the long acute bill, which is either straight or curved upward. Recurvirostra is a 4-toed, and full-webbed; the bill is decidedly recurved, flattened, and tapers to a needle-like point; the body is depressed; the plumage underneath is thickened as in water-birds. The species swim well. Himantopus is 3 toes, semipalmate, the bill nearly straight, and not flattened; in relative length of leg it is probably not surpassed by any bird whatsoever. " Elliot Coues, 1884

"Upper part ashy-gray, with scarcely a shade, and only on the rump, under parts similarly grayish-white, without a rusty tinge, the middle of the belly, the rest more heavily shaded. Wings and tail with comparatively little whitish edging - tail at least with no more than that of P. carolonensis. Sides of the head and neck white; top of the head, and the throat, black.

"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

"Ammodramus. Seaside Sparrow. Bill remarkably slender and lengthened for this family, with culmen toward end, gonys straight, and sometimes an evident lobation of the cutting edge of the upper mandible. Wings short and rounded, yet longer than tail; inner secondaries, though not elongate, reaching nearly to end of primaries when wing is closed; point formed by 2d-4th quills.

Tail shorter or not longer than wings, much rounded, of narrow, stiffish, sharp-pointed feathers.

Edge of wing bright yellow; a yellow spot of buff stripe on head; upper parts olive-gray or quite blackish, streaky." Elliot Coues, 1884
