"Junco hiemalis. Eastern Snow-bird. Black Snow-bird. Blackish-ash, below abruptly pure white from the breast, the sides shaded with ashy. In the summer, and most fall and winter specimens, the upper parts have a more grayish, or even a decidedly brownish, cast, and the inner secondaries are edged with pale bay. The slaty-black intense on the head; belly and crissum pure white, the line between the two transverse or convex forward; wings and tail blackish, with slightly hoary edging of some feathers; 2-3 lateral tail feathers pure white, wholly or in great part. No rusty brown on back or sides; any shade on the sides ashy, not pinkish. Bill pinkish-white, or flesh-color, usually black-tipped." Elliot Coues, 1884

"Melospiza fasciata. Song Sparrow. Silver-tongue. Below, white, slightly shaded with brownish on the flanks and crissum; with numerous black-centred, brown-edged streaks cross breast and along sides, usually forming a pectoral blotch and coalescing into maxillary stripes bounding the white throat; crown dull bay, with fine black streaks, divided in the middle and bounded on either side by ashy-whitish lines; vague brown or dusky and whitish markings on sides of the head; a brown post-ocular stripe over the gray auriculars, and another, not so well defined, from angle of mouth below the auriculars; the interscapular streaks black, with bay and ashy-white edgings; rump and cervix grayish-brown, with merely a few bay marks; wings with dull bay edgings, the coverts and inner quills marked like the interscapulars; tail plain brown, with darker shaft lines, on the middle feathers at least, and often with obsolete transverse wavy markings. Very constant in plumage, the chief difference being in the sharpness and breadth of the markings, due in part to the wear of the feathers. In worn midsummer plumage, the streaking is very sharp, narrow, and black, from wearing of the rufous and whitish, especially observable below where the streaks contrast with white, and giving the impression of heavier streaking than in fall and winter, when in fresher feather, the markings are softer and more suffuse. The aggregation of spots into a blotch on the middle of the breast is usual. Bill dark brown, paler below; feet pale brow." Elliot 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. Feet large and stout, reaching outstretched about to the end of tail; tarsus about equal to middle toe and claw in length; lateral toes of equal lengths, very short, their claws under reaching base of middle claw. Tail shorter or not longer than wings, much rounded, of narrow, stiffish, sharp-pointed feathers. Embracing small streaky marsh sparrows, especially of the sea-coast, but not exclusively maritime, as long supposed; remarkable for slenderness of the bill, sharp narrow tail-feathers, and stout feet fitted for grasping slender swaying reeds. Edge of wing bright yellow; a yellow spot of buff stripe on head; upper parts olive-gray or quite blackish, streaky." Elliot Coues, 1884

"Passerculs bairdi. Baird's Savanna Sparrow. Inner secondaries less elongated, rarely equaling the primaries in the closed wings. First 4 quills about equal and longest. Hind toe and claw about equaling the middle toe and claw, its claw about equaling the digit. Tail shorter than wing, lightly double-rounded (central and outer pair of feathers both little shorter than the intermediate ones). Top of head streaked with black and rich brownish-yellow. or buff, the former predominating laterally, the latter chiefly as a median stripe, but also suffusing the nape and sides of head in greater or less degree.

Rump variegated with gray and chestnut-brown, different in shade from that of the back. Under parts dull white, usually with a faint ochrey tinge on the breast, but often without; a circlet of small, sharp, sparse, dusky streaks across the breast, continuous with others, longer and mostly lighter, along the whole sides, and with others, again, extending up the sides of the neck into small vague maxillary and aurigular markings. When the feathers are perfectly arranged these lateral head-markings are seen to be post-ocular stripe just over the auricular spot, a streak starting from the angle of the mouth, and another heavier one parallel with and below this, running directly into the pectoral ones. Quills without special marking, excepting the elongated inner secondaries, which correspond with scapulars. Tail the same, slightly whitish-edge. Upper mandible mostly dark, lower pale. Feet flesh-colored." Elliot Coues, 1884

Tail of Forster's Tern

"Sterna forsteri. Forster's Tern. Tail 5.00 - 8.00, forked 2.50-5.00." Elliot Coues, 1884

"Sterna aleutica. Aleutian Tern. Bill of ordinary shape, as in hirundo, macrura, etc., entirely black. Feet small, as in the species just named, but the webs more deeply incised; emargination not so great, however, as in Hydrochelidon; much as in Haliplana. Tibia bare to the usual extent. Wings and tail exactly as in Sterna proper, the latter, in its length and depth of fork, recalling macrura and forsteri. Crown and nape black; a large white frontal crescent, the horns of which reach to the posterior border of the eyes, the convexity of which extends into the nasal fossae, the concavity of which is opposite the anterior border of the eyes; thus broader than in most species similarly marked. The black vertex sends through the eye a band that crosses the cheeks and reaches the bill just posterior to the point of greatest extension of the feathers on the latter. The chin, auriculars, and other parts of the head bordering this vitta below, and pure white, presently deepening insensibly into the hue of the under parts. Tail wholly pure white; no pearly wash on either vane of any of the feathers. Upper parts at large dark pearl-gray, with a dull leaden hue, different from the clear pearly of macrura, etc., yet not of the smoky cast of panayensis, etc.; it is a tint intermediate between these, that I find difficult to name satisfactorily. The whole under parts, from the white of the chin, just noticed, to the under tail-coverts, paler and more decidedly pearly, more nearly as in full-plumaged macrura, yet more grayish. Both under and upper tail-coverts, like the tail, white. The color of the back mounts on the neck behind to the black of the nape without intervention of the white. Under wing-coverts and edge of wing pure white; as are all the shafts of the primaries. Primaries blackish lead-color, with silvery hoariness, and each with a large white space on inner web; this white space on the first primary occupies at the base the whole width of the inner web, but grows narrower toward the tip of the feather, ending about an inch from the tip, which is wholly blackish lead-color, this color running down as a narrow margining of the inner vane for two inches or more."

"Sterna (T.) caspia. Caspian Tern. Imperial Tern. Bill dark vermilion red, growing and somewhat "diaphanous" toward the tip. Pileum and occipital crest glossy greenish-black, extending to below the lower level of the eyes, and occupying the termination of the feathers on the side of the mandible to the exclusion of the white; lower eyelid white, forming a noticeable spot on the greenish; a white streak along sides of upper mandible, not extending to the end of the feathers. mantle pearl-blue, the line of demarcation between it and the white rather indefinite, both on nape and rump; most of the tail-feathers, and especially the central ones, retaining a more or less pearly tint. Shafts of the primaries yellowish-white; primaries grayish-black, but, when new, so heavily silvered over as to appear of a light hoary gray, especially on their superior aspects. On the inner web of all there is a central light field; this is very narrow, even on the first primary, although it runs considerable distance, and on the others it rapidly grows less; and it has no trenchant line of division of the primaries from the darker portions of the feather. whole inner web of secondaries pure white, outer pearl-blue. Legs and feet black." Elliot Coues, 1884

"Sterna (T.) elegans. Elegant Tern. Princely Tern. Bill bright red, salmon-colored toward tip. Feet black; soles and under surfaces of claws slightly yellowish. crown of head, including long-flowing occipital crest, pure black, reaching down on the sides of the head to a straight line just on a level with the lower border of the eye; the white of the cheeks accompanying the black to the foremost point of extension of the feathers in the nasal fossae. All the under parts rosy-white, with satin gloss. Tail entirely pure white, longer and more deeply forked than in winter. Back and wings pale pearl-blue; the usual pattern of coloration of the primaries." Elliot Coues, 1884

"Sterna dougalli. Roseate Tern. Paradise Tern. Bill about as long as head or foot, straight, slender, compressed, very acute; gonys longer than rami, former straight, latter concave in outline, with acute but not prominent angle between them. Wings shorter than usual, 1st primary little longer than next, all rounded. Tail exceedingly long and deeply forked, with very narrow filamentous outer feathers. Tibia slightly denuded; tarsus a little shorter than middle toe and claw. Whole form trim and elegant. Bill black, the extreme point yellowish, the base for a little distance, and inside of mouth, red. Feet bright yellowish-red; claws black. Cap lustrous black, very ample, reaching to lower border of eyes; under eyelid white, as is a streak to end of feathers on bill. Neck all around and entire under parts snowy white, tinted with lovely rose-pink. Mantle delicate pale pearly, over all the upper parts from the neck, including rump and base of tail, fading however to white on tips of tertials and inner webs of secondaries. Long tail-feathers white with a faint pearly tint. Primaries grayish-black, strongly silvered when fresh; outer web of the first blackish; inner webs of all pure white for more than half their breadth, this white stripe broadest on the first, toward the base of which it occupies the whole web, and on all of them continued to and usually around the very tips; shafts of all the quills white both sides nearly to end."

"Sterna (T.) maxima. Cayenne Tern. Royal Tern. Adult in summer: Pileum glossy greenish-black, not extending below eyes, so narrow on side of upper mandible that a broad white streak extends to extreme tip of the feathers. Mantle exceedingly light pearl-blue, fading imperceptibly into white on the rump and towards the extremities of the tertials. Tail white, with a faint tinge of pearly, especially on the central feathers and inner webs of the other. Secondaries pure white for their whole length except a small space on the outer web near the tip, which is grayish-blue, deeper than the mantle. Outer web of first primary grayish-black; in the inner web of the same has a space of black extending the whole length of the feather, very narrow at the base, widening as it runs toward the tip. within 1 & 1/2 inches of which it occupies the whole web; the rest of the web white. separated from the black by a straight distinct line of division. The second, third, fourth, and fifth primaries have the same general characteristics, but the white space grows narrow and shorter, and round up further in the centre than along the edge of the web, so that for a little way from its end it has a border of blackish along its outer margin; other primaries wholly pearl-blue, their inner webs margined with white. Bill coral and orange-red, with a slightly lighter tip; feet blackish, their soles dull yellowish." Elliot Coues, 1884

"Sterna (T.) cantiaca. Sandwich Tern. Ducal Tern. Bill black, the tip 1/2 to 3/4 an inch bright yellow, sharply defined against the black; "inside of mouth deep blue." Feet dull black. Pileum and occipital crest glossy black, with a tinge of green; the color extending just below the eyes, but leaving a space along the side of the mandible white to the extremity of the feathers. Mandible exceedingly light pearly-blue, fading on the rump and upper tail-coverts into pure white; but the rectrices themselves have a slight shade of pearly-bluish. Primaries colored as in maxima. On the inner web of the first the black space is broad and deep in color; when about 1& 1/2 inches from the apex of the quill it quite suddenly grows wider, so as to exclude the white portion from the tip altogether. The second, third, and fourth primaries have the same general pattern, but he white runs up further on the central portion than on the edge of the web, so that toward its end it receives a narrow edging of blackish. The other primaries have no blackish, but are simply pearl-blue, with broad white margins along the whole length of heir inner webs. The outer primaries are all heavily silvered when the quills are new.
