"Geococcyx californianus. Ground Cuckoo. Chaparral Cock. Road Runner. Snake Killer. Paisano. Most of the feathers of the head and neck bristle-tipped; a naked area around eye; crown crested; plumage course. Above, lustrous bronzy or coppery-green, changing to dark steel-blue on the head and neck, to purplish-violet on the middle tail-feathers; everywhere except on rump conspicuously streaked with white, mixed with tawny on the head, neck, and wings - this white and buff streaking consisting of the edges of the feathers, which are frayed out, fringe-like, producing a peculiar effect. Breast, throat and sides of neck mixed tawny-white and black; other under parts dull soiled whitish. Primaries white, tipped and with oblique white space on outer webs. Lateral tail-feathers steel-blue with green violet reflections, their outer webs fringed part way with white, their tips broadly white. Lower back and rump, where covered by the folded wings, dark colored and unmarked; under surface of wings sooty-brown. Bare space around eye bluish and orange. Bill dark horn-color; feet the same, the larger scales yellowish." Elliot Coues, 1884

"Cyanocitta stelleri macrolopha. Long-crested Jay. Upper parts sooty umber-brown, with a faint blue tinge, blackening on head and neck all around in decided contrast, passing on rump and upper tail-coverts into beautiful light cobalt-blue; passing on fore breast into the same blue which occupies all the under parts. Crest black, but faced on forehead with bluish-white, which, when the feathers are not disturbed, runs in two parallel lines from the nostrils upward - these colored tips of the feathers of firmer texture than their basal portions. One or both eyelids patched with white. Chin abruptly whitish, streaky. Exposed surfaces of wings rich indigo-blue, most intense on the inner secondaries, which, with the greater coverts, are regularly and firmly barred across both webs with black; the outer webs of the primaries lighter blue, more like that of the rump or under parts, Upper surface of tail rich indigo, like the secondaries, and similarly black-barred; these bands most distinct towards the end and on the outer webs of the feathers; tail viewed from below appearing mostly blackish. Iris dark. Bill and feet black." Elliot Coues , 1884

"Lagopus leucurus. White-tailed Ptarmigan. Rocky Mountain Snow Grouse. Male and Female in winter: Entirely snow-white; bill black, rather slender, and general size and proportions nearly as in L. rupestris. Male and female, in summer: Tail, most of the wing, and lower parts from the breast, remaining white; rest of the plumage minutely marked with black, white, and tawny or grayish-brown, varying in precise character almost with every specimen; but there is no difficulty in recognizing this whit-tailed species, of alpine distribution in Western N. A. from the Arctic regions to New Mexico (lat. 37 degrees)." Elliot Coues, 1884

"Kentucky Warbler. Oporornis formosus.

Beneath, soiled white, shading behind into pale cinnamon, the throat and breast obsoletely streaked, and the under tail-covers barred, with dusky. Quills of the wings rather darker than the back, with similar markings on the outer webs. Middle tail-feathers like the back, with many dark bars of equal width with the lighter ones; lateral tail-feathers similarly marked on the outer webs, plain on the inner webs, with a broad subterminal black bar on both webs, and cinnamon-brown tips, the latter usually marbled with dusky; outer feathers with several blackish and cinnamon bars on both webs. Bill and feet dark horn color, the former paler at base below." Elliot Coues, 1884
