All the specimens of a large series from Fort Whipple, Arizona, as well as most others from west of the Rocky Mountains to the Pacific coast, agree in the characters given above, as distinguished from eastern specimens of socialis. The variations with age and season are simple parallels of those in socialis.
Habits. The references in the preceding article to the Chipping Sparrow as occurring in the Middle and Western Provinces of the United States, are to be understood as applying to the present race.
Spizella pallida, Bonap
CLAY-COLORED SPARROW
Emberiza pallida, Sw. F. Bor.-Am. II, 1831, 251 (not of Audubon). Spizella pallida, Bonap. List, 1838.—Baird, Birds N. Am. 1858, 474. Spinites pallidus, Cabanis, Mus. Hein. 1851, 133. Emberiza shattucki, Aud. Birds Am. VII, 1843, 347, pl. ccccxciii. Spizella shattucki, Bonap. Conspectus, 1850, 480.
Sp. Char. Smaller than S. socialis. Back and sides of hind neck ashy. Prevailing color above pale brownish-yellow, with a tinge of grayish. The feathers of back and crown streaked conspicuously with blackish. Crown with a median pale ashy and a lateral or superciliary ashy-white stripe. Beneath whitish, tinged with brown on the breast and sides, and an indistinct narrow brown streak on the edge of the chin, cutting off a light stripe above it. Ear-coverts brownish-yellow, margined above and below by dark brown, making three dark stripes on the face. Bill reddish, dusky towards tip. Legs yellow. Length, 4.75; wing, 2.55.
Hab. Upper Missouri River and high central plains to the Saskatchewan country. Cape St. Lucas, Oaxaca, March (Scl. 1859, 379); Fort Mohave (Cooper, P. A. N. S. Cal. 1861, 122); San Antonio, Texas, spring (Dresser, Ibis, 1865, 489; common).
The ashy collar is quite conspicuous, and streaked above with brown. The rump is immaculate. The streaks on the feathers of the crown almost form continuous lines, about six in number. The brown line above the ear-coverts is a post-ocular one. That on the side of the chin forms the lower border of a white maxillary stripe which widens and curves around behind the ear-coverts, fading into the ashy of the neck. The wing-feathers are all margined with paler, and there is an indication of two light bands across the ends of the coverts.
The young of this species is thickly streaked beneath over the throat, breast, and belly, with brown, giving to it an entirely different appearance from the adult. The streaks in the upper parts, too, are darker and more conspicuous. The margins of the feathers are rather more rusty.
This species is readily distinguishable from the other American Spizellas, except S. breweri (which see), in the dark streaks and median ashy stripe on the crown, the paler tints, the dark line on the side of the chin, etc.
Habits. The Clay-colored Bunting was first discovered by Richardson, and described by Swainson, in the Fauna Bor.-Amer. The only statement made in regard to it is that it visited the Saskatchewan in considerable numbers, frequented the farm-yard at Carlton House, and was in all respects as familiar and confiding as the common House Sparrow of Europe.
The bird given by Mr. Audubon as the pallida has been made by Mr. Cassin a different species, S. breweri, and the species the former gives in his seventh volume of the Birds of America as Emberiza shattucki is really this species. It was found by Mr. Audubon’s party to the Yellowstone quite abundant throughout the country bordering upon the Upper Missouri. It seemed to be particularly partial to the small valleys found, here and there, along the numerous ravines running from the interior and between the hills. Its usual demeanor is said to greatly resemble that of the common Chipping Sparrow, and, like that bird, it has a very monotonous ditty, which it seems to delight to repeat constantly, while its mate is more usefully employed in the duties of incubation. When it was approached, it would dive and conceal itself amid the low bushes around, or would seek one of the large clusters of wild roses so abundant in that section. The nest of this species is mentioned as having been usually placed on a small horizontal branch seven or eight feet from the ground, and occasionally in the broken and hollow branches of trees. These nests are also stated to have been formed of slender grasses, but in so slight a manner as, with their circular lining of horse or cattle hair, to resemble as much as possible the nest of the common socialis. The eggs were five in number, and are described as being blue with reddish-brown spots. These birds were also met with at the Great Slave Lake region by Mr. Kennicott, in the same neighborhood by B. R. Ross and J. Lockhart, and in the Red River settlements by Mr. C. A. Hubbard and Mr. Donald Gunn.
Captain Blakiston noted the arrival of this bird at Fort Carlton on the 21st of May. He speaks of its note as very peculiar, resembling, though sharper than, the buzzing made by a fly in a paper box, or a faint imitation of the sound of a watchman’s rattle. This song it utters perched on some young tree or bush, sometimes only once, at others three or four times in quick succession.
Their nests appear to have been in all instances placed in trees or in shrubs, generally in small spruces, two or three feet from the ground. In one instance it was in a clump of small bushes not more than six inches from the ground, and only a few rods from the buildings of Fort Resolution.
Both this species and the S. breweri were found by Lieutenant Couch at Tamaulipas in March, 1855. It does not appear to have been met with by any other of the exploring expeditions, but in 1864, for the first time, as Dr. Heermann states, to his knowledge, these birds were found quite plentiful near San Antonio, Texas, by Mr. Dresser. This was in April, in the fields near that town. They were associating with the Melospiza lincolni and other Sparrows. They remained about San Antonio until the middle of May, after which none were observed.
The eggs of this species are of a light blue, with a slight tinge of greenish, and are marked around the larger end with spots and blotches of a purplish-brown, rather finer, perhaps, than in the egg of S. socialis, though very similar to it. They average .70 of an inch in length, and vary in breadth from .50 to .52 of an inch.
Spizella pallida, var. breweri, Cassin
BREWER’S SPARROW
Emberiza pallida, Aud. Orn. Biog. V, 1839, 66, pl. cccxcviii, f. 2.—Ib. Synopsis, 1839.—Ib. Birds Am. III, 1841, 71, pl. clxi (not of Swainson, 1831). Spizella breweri, Cassin, Pr. A. N. Sc. VIII, Feb. 1856, 40.—Baird, Birds N. Am. 1858, 475.—Cooper, Orn. Cal. 1, 209.
Sp. Char. Similar to S. pallida; the markings including the nuchal collar more obsolete; no distinct median and superciliary light stripes. The crown streaked with black. Some of the feathers on the sides with brown shafts. Length, 5 inches; wing, 2.50. Young streaked beneath, as in pallida.
Hab. Rocky Mountains of United States to the Pacific coast.
This race is very similar to the S. pallida, and requires close and critical comparison to separate it. The streaks on the back are narrower, and the central ashy and lateral whitish stripes of the crown are scarcely, if at all, appreciable. The clear unstreaked ash of the back of the neck, too, is mostly wanting. The feathers along the sides of the body, near the tibia, and occasionally elsewhere on the sides, have brownish shafts, not found in the other. The differences are perhaps those of race, rather than of species, though they are very appreciable.
Habits. This species bears a very close resemblance to the S. pallida in its external appearance, but there are certain constant differences which, with the peculiarities of their distinctive distributions and habits, seem to establish their specific separation. The present bird is found from the Pacific coast to the Rocky Mountains, and from the northern portion of California to the Rio Grande and Mexico. Dr. Kennerly found it in February, 1854, throughout New Mexico, from the Rio Grande to the Great Colorado, along the different streams, where it was feeding upon the seeds of several kinds of weeds.
Dr. Heermann, while accompanying the surveying party of Lieutenant Williamson, between the 32d. and 35th parallels, found these Sparrows throughout his entire route, both in California and in Texas. On the passage from the Pimos villages to Tucson he observed large flocks gleaning their food among the bushes as they were moving southward. In the Tejon valley, during the fall season, he was constantly meeting them associated with large flocks of other species of Sparrows, congregated around the cultivated fields of the Indians, where they find a bountiful supply of seeds. For this purpose they pass the greater part of the time upon the ground.
Dr. Woodhouse also met with this Sparrow throughout New Mexico, wherever food and water were to be found in sufficient quantity to sustain life.
In Arizona, near Fort Whipple, Dr. Coues states that this bird is a rare summer resident. He characterizes it as a shy, retiring species, keeping mostly in thick brush near the ground.
Mr. Ridgway states that he found this interesting little Sparrow, while abundant in all fertile portions, almost exclusively an inhabitant of open situations, such as fields or bushy plains, among the artemesia especially, where it is most numerous. It frequents alike the valleys and the mountains. At Sacramento it was the most abundant Sparrow, frequenting the old fields. In this respect it very much resembles the eastern Spizella pusilla, from which, however, it is in many respects very different.
The song of Brewer’s Sparrow, he adds, for sprightliness and vivacity is not excelled by any other of the North American Fringillidæ, being inferior only to that of the Chondestes grammaca in power and richness, and even excelling it in variety and compass. Its song, while possessing all the plaintiveness of tone so characteristic of the eastern Field Sparrow, unites to this quality a vivacity and variety fully equalling that of the finest Canary. This species is not resident, but arrives about the 9th of April. He found its nest and eggs in the Truckee Reservation, early in June. The nests were in sage-bushes about three feet from the ground.
Dr. Cooper found small flocks of this species at Fort Mohave, after March 20, frequenting grassy spots among the low bushes, and a month later they were singing, he adds, much like a Canary, but more faintly. They are presumed to remain in the valley all summer.
The eggs, four in number, are of a light bluish-green color, oblong in shape, more rounded at the smaller end than the eggs of the socialis, and the ground is more of a green than in those of S. pallida. They are marked and blotched in scattered markings of a golden-brown color. These blotches are larger and more conspicuous than in the eggs of the other species. They measure .70 by .51 of an inch.
Spizella atrigularis, Baird
BLACK-CHINNED SPARROW
Spinites atrigularis, Cabanis, Mus. Hein. 1851, 133. Spizella atrigularis, Baird, Birds N. Am. 1858, 476, pl. lv, f. 1.—Ib. Mex. Bound. II, Birds, p. 16, pl. xvii, f. 1.—Cooper, Orn. Cal. 1, 210. Struthus atrimentalis, Couch, Pr. A. N. Sc. Phil. VII, April, 1854, 67.
Sp. Char. Tail elongated, deeply forked and divaricated. General color bluish-ash, paler beneath, and turning to white on the middle of the belly. Interscapular region yellowish-rusty, streaked with black. Forehead, loral region, and side of head as far as eyes, chin, and upper part of throat black. Quills and tail-feathers very dark brown, edged with ashy. Edges of coverts like the back. No white bands on the wings. Bill red, feet dusky. Immature birds, and perhaps adult female, without any black on head. Length, 5.50; wing, 2.50; tail, 3.00.
Hab. Mexico, just south of the Rio Grande; Fort Whipple, Ariz. (Coues); Cape St. Lucas.
This species is about the size of S. pusilla and S. socialis, resembling the former most in its still longer tail. This is more deeply forked and divaricated, with broader feathers than in either. The wing is much rounded; the fourth quill longest; the first almost the shortest of the primaries.
Habits. This species is a Mexican bird, found only within the limits of the United States along the borders. But little is known as to its history. It is supposed to be neither very abundant nor to have an extended area of distribution. It was met with by Dr. Coues in the neighborhood of Fort Whipple, Arizona, where it arrives in April and leaves again in October, collecting, before its departure, in small flocks. In the spring he states that it has a very sweet and melodious song, far surpassing in power and melody the notes of any other of this genus that he has ever heard.
Dr. Coues furnishes me with the following additional information in regard to this species: “This is not a common bird at Fort Whipple, and was only observed from April to October. It unquestionably breeds in that vicinity, as I shot very young birds, in August, wanting the distinctive head-markings of the adult. A pair noticed in early April were seemingly about breeding, as the male was in full song, and showed, on dissection, highly developed sexual organs. The song is very agreeable, not in the least recalling the monotonous ditty of the Chip Bird, or the rather weak performances of some other species of the genus. In the latter part of summer and early autumn the birds were generally seen in small troops, perhaps families, in weedy places, associating with the western variety of Spizella socialis, as well as with Goldfinches.”
Lieutenant Couch met with individuals of this species at Agua Nueva, in Coahuila, Mexico, in May, 1853. They were found in small flocks among the mountains. Their nest and eggs are unknown.
Genus MELOSPIZA, Baird
Melospiza, Baird, Birds N. Am. 1868, 478. (Type, Fringilla melodia, Wils.)
Melospiza melodia.
2637 ♂
Gen. Char. Body stout. Bill conical, very obsoletely notched, or smooth; somewhat compressed. Lower mandible not so deep as the upper. Commissure nearly straight. Gonys a little curved. Feet stout, not stretching beyond the tail; tarsus a little longer than the middle toe; outer toe a little longer than the inner; its claw not quite reaching to the base of the middle one. Hind toe appreciably longer than the middle one. Wings quite short and rounded, scarcely reaching beyond the base of the tail; the tertials considerably longer than the secondaries; the quills considerably graduated; the fourth longest; the first not longer than the tertials, and almost the shortest of the primaries. Tail moderately long, rather longer from coccyx than the wings, and considerably graduated; the feathers oval at the tips, and not stiffened. Crown and back similar in color, and streaked; beneath thickly streaked, except in M. palustris. Tail immaculate. Usually nest on ground; nests strongly woven of grasses and fibrous stems; eggs marked with rusty-brown and purple on a ground of a clay color.
Melospiza melodia.
This genus differs from Zonotrichia in the shorter, more graduated tail, rather longer hind toe, much more rounded wing, which is shorter; the tertiaries longer; the first quill almost the shortest, and not longer than the tertials. The under parts are spotted; the crown streaked, and like the back.
There are few species of American birds that have caused more perplexity to the ornithologist than the group of which Melospiza melodia is the type. Spread over the whole of North America, and familiar to every one, we find each region to possess a special form (to which a specific name has been given), and yet these passing into each other by such insensible gradations as to render it quite impossible to define them as species. Between M. melodia of the Atlantic States and M. insignis of Kodiak the difference seems wide; but the connecting links in the intermediate regions bridge this over so completely that, with a series of hundreds of specimens before us, we abandon the attempt at specific separation, and unite into one no less than eight species previously recognized.
Taking, then, the common Song Sparrow of the Eastern Atlantic States (M. melodia) as the starting-point, and proceeding westward, we find quite a decided difference (in a variety fallax) when we reach the Middle Province, or that of the Rocky Mountains. The general tints are paler, grayer, and less rusty; the superciliary stripe anteriorly more ashy; the bill, and especially the legs, more dusky, the latter not at all to be called yellow. The bill is perhaps smaller and, though sometimes equal to the average of eastern specimens, more slender in proportion. In some specimens (typical fallax) the streaks are uniform rufous without darker centres,—a feature I have not noticed in eastern melodia. Another stage (heermanni) is seen when we reach the Pacific coast of California, in a darker brown color (but not rufous). Here the bill is rather larger than in var. fallax, and the legs colored more like typical melodia. In fact, the bird is like melodia, but darker. The stripes on the back continue well defined and distinct. M. samuelis (=gouldi) may stand as a smaller race of this variety.
Proceeding northward along the Pacific coast, another form (var. guttata), peculiar to the coast of California, is met with towards and beyond the mouth of the Columbia (coming into Southern California in winter). This is darker in color, more rufous; the stripes quite indistinct above, in fact, more or less obsolete, and none, either above or below, with darker or blackish centres. The sides, crissum, and tibia are washed with ochraceous-brown, the latter perhaps darkest. The bill is proportionally longer and more slender. This race becomes still darker northward, until at Sitka (var. rufina) it shows no rufous tints, but a dusky olive-brown instead, including the streaks of the under parts. The markings of the head and back are appreciable, though not distinct. The size has become considerably larger than in eastern melodia, the average length of wing being 3.00, instead of 2.60.
The last extreme of difference from typical melodia of the east is seen in the variety insignis from Kodiak. Here the size is very large: length, 7.00; extent, 10.75; wing, 3.20. The bill is very long (.73 from forehead), the color still darker brown and more uniform above; the median light stripe of vertex scarcely appreciable in some specimens; the superciliary scarcely showing, except as a whitish spot anteriorly. The bill and feet have become almost black.
The following synopsis may serve as a means by which to distinguish the several races of this species, as also the two remaining positive species of the genus:—

Sp. Char. General tint of upper parts rufous and distinctly streaked with rufous-brown, dark-brown, and ashy-gray. The crown is rufous, with a superciliary and median stripe of dull gray, the former lighter; nearly white anteriorly, where it sometimes has a faint shade of yellow, principally in autumn; each feather of the crown with a narrow streak of black forming about six narrow lines. Interscapulars black in the centre, then rufous, then pale grayish on the margin, these three colors on each feather very sharply contrasted. Rump grayer than upper tail-coverts, both with obsolete dark streaks. There is a whitish maxillary stripe, bordered above and below by one of dark rufous-brown, and with another from behind the eye. The under parts are white; the jugulum and sides of body streaked with clear dark-brown, sometimes with a rufous suffusion. On the middle of the breast these marks are rather aggregated so as to form a spot. No distinct white on tail or wings. Length of male, 6.50; wing, 2.58; tail, 3.00. Bill pale brown above; yellowish at base beneath. Legs yellowish.
Hab. Eastern United States to the high Central Plains.
Specimens vary somewhat in having the streaks across the breast more or less sparse, the spot more or less distinct. In autumn the colors are more blended, the light maxillary stripe tinged with yellowish, the edges of the dusky streaks strongly suffused with brownish-rufous.
The young bird has the upper parts paler, the streaks more distinct; the lines on the head scarcely appreciable. The under parts are yellowish; the streaks narrower and more sharply defined dark brown.
As already stated, this species varies more or less from the above description in different parts of North America, its typical races having received specific names, which it is necessary to retain for them as varieties.
Habits. The common Song Sparrow of eastern North America has an extended range of distribution, and is resident throughout the year in a large part of the area in which it breeds. It nests from about South Carolina north to the British Provinces of Nova Scotia and New Brunswick at the east, and to a not well-defined limit in British America. The most northern points to which it has been traced are the plains of the Saskatchewan and the southern shore of Lake Winnepeg, in which latter place Mr. Kennicott found it breeding. It is said by Dr. Coues to breed in South Carolina, and by Mr. Audubon in Louisiana, but I have never seen any of their eggs from any point south of Washington. In winter it is found from Massachusetts, where only a few are observed, to Florida. It is most abundant at this period in North and South Carolina. It is not mentioned in Dr. Gerhardt’s list as being found in Northern Georgia at any season of the year. Mr. Ridgway informs me that it does not breed in Southern Illinois. Its song is not popularly known there, though he has occasionally heard it just before these Sparrows were leaving for the north. This species winters there in company with the Z. albicollis and Z. leucophrys, associating with the former, and inhabiting brush-heaps in the clearings.
To Massachusetts, where specimens have been taken in every month of the year, and where they have been heard to sing in January, they return in large numbers usually early in March, sometimes even in February. It is probable that these are but migrants, passing farther north, and that our summer visitants do not appear among us until the middle of April, or just as they are about to breed. They reach Maine from the 15th to the 25th, and breed there the middle of May. In Massachusetts they do not have eggs until the first week in May, except in very remarkable seasons, usually not until after the Bluebird has already hatched out her first brood, and a week later than the Robin.
The tide of returning emigration begins to set southward early in October. Collecting in small loose flocks, probably all of each group members of the same family, they slowly move towards the south. As one set passes on, another succeeds, until the latter part of November, when we no longer meet with flocks, but solitary individuals or groups of two or three. These are usually a larger and stouter race, and almost suggest a different species. They are often in song even into December. They apparently do not go far, and are the first to return. In early March they are in full song, and their notes seem louder, clearer, and more vibratory than those that come to us and remain to breed.
The Song Sparrow, as its name implies, is one of our most noted and conspicuous singers. It is at once our earliest and our latest, as also our most constant musician. Its song is somewhat brief, but is repeated at short intervals, almost throughout the days of spring and early summer. It somewhat resembles the opening notes of the Canary, and though less resonant and powerful, much surpasses them in sweetness and expression. Plain and homely as this bird is in its outward garb, its sweet song and its gentle confiding manners render it a welcome visitor to every garden, and around every rural home wherein such attractions can be appreciated. Whenever these birds are kindly treated they readily make friends, and are attracted to our doorsteps for the welcome crumbs that are thrown to them; and they will return, year after year, to the same locality, whenever thus encouraged.
The song of this Sparrow varies in different individuals, and often changes, in the same bird, in different parts of the year. It is even stated by an observing naturalist—Mr. Charles S. Paine, of Randolph, Vt.—that he has known the same bird to sing, in succession, nine entirely different sets of notes, usually uttering them one after the other, in the same order. This was noticed not merely once or during one season, but through three successive summers. The same bird returned each season to his grounds, and came each time provided with the same variety of airs.
Mr. Nuttall, who dwells with much force upon the beauty and earnestness of expression of the song of this species, has also noticed and remarked upon the power of individuals to vary their song, from time to time, with very agreeable effect, but no one has recorded so remarkable an instance as that thus carefully noted by Mr. Paine.
These birds are found in almost any cultivated locality where the grounds are sufficiently open. They prefer the edges of open fields, and those of meadows and low grounds, but are rarely found in woods or in thick bushes, except near their outer edges. They nest naturally on the ground, and in such situations a large majority build their nests. These are usually the younger birds. A portion, almost always birds of several summers, probably taught by sad experiences of the insecurity of the ground, build in bushes. A pair which had a nest in an adjoining field had been robbed, by a cat, of their young when just about to fly. After much lamentation, and an interval of a week, I found this same pair, which I easily recognized, building their nest among some vines near my house, some eight feet from the ground. They had abandoned my neighbor’s grounds and taken refuge close to my house. This situation they resorted to afterwards for several successive summers, each season building two nests, never using the same nest a second time, although each time it was left as clean and in as good condition as when first made. Indeed, this species is remarkable for its cleanliness, both in its own person and in its care of nestlings and nests.
