A History of North American Birds, Land Birds. Volume 2

Subfamily SPIZINÆ

Char. Bill variable, always large, much arched, and with the culmen considerably curved; sometimes of enormous size, and with a greater development backward of the lower jaw, which is always appreciably, sometimes considerably, broader behind than the upper jaw at its base; nostrils exposed. Tail rather variable. Bill generally black, light blue, or red. Wings shorter than in the first group. Gape almost always much more strongly bristled. Few of the species sparrow-like or plain in their appearance; usually blue, red, or black and white; except in one or two instances the sexes very different in color.

The preceding diagnosis is intended to embrace the brightly colored passerine birds of North America, different in general appearance from the common Sparrows. It is difficult to draw the line with perfect strictness, so as to separate the species from those of the preceding group, but the bill is always more curved, as well as larger, and the colors are brighter. They resemble quite closely, at a superficial glance, the Coccothraustinæ, but may be readily distinguished by absence of the projecting tufts surrounding the base of the upper mandible, shorter, more rounded wings, and longer tarsi.

The genera may be most conveniently arranged as follows:—

A. Wings decidedly longer than the tail. Eggs plain blue or white, unspotted.

a. Feet very stout, reaching nearly to the end of the tail. Species terrestrial.

Calamospiza. Bill moderate, the commissure with a deep angle posteriorly and prominent lobe behind it; anteriorly nearly straight; commissure of lower mandible with a prominent angle. Outer toe longer than the inner, both nearly as long as the posterior. Outer four primaries about equal, and abruptly longer than the rest. Tertials nearly equal to primaries. Tail-feathers broad at tips. Color: black with white spot on wing in ♂, brownish streaks in ♀. Nest on or near ground; eggs plain pale blue.

Euspiza. Bill weaker, the commissure with a more shallow angle, and much less prominent sinuation behind it; anteriorly distinctly sinuated. Outer toe shorter than inner, both much shorter than the posterior one. First primary longest, the rest successively shorter. Tertials but little longer than secondaries. Tail-feathers attenuated at tips. Color: back brown streaked with black; throat white; jugulum yellow or ashy; with or without black spot on fore neck. A yellow or white superciliary stripe. Nest on or near ground; eggs plain pale blue.

b. Feet weaker, scarcely reaching beyond lower tail-coverts; species arboreal.

a. Size large (wing more than 3.50 inches)

Hedymeles. Upper mandible much swollen laterally. Colors: no blue; upper parts conspicuously different from the lower. Wings and tail with white patches; axillars and lining of wing yellow or red. Female streaked. Nest in a tree or bush; eggs greenish, thickly spotted.

Guiraca. Upper mandible flat laterally. Colors: ♂ deep blue, with two rufous bands on wings; no white patches on wings or tail; axillars and lining of wing blue; ♀ olive-brown without streaks. Nest in a bush; eggs plain bluish-white.

b. Size very small (wing less than 3.00 inches)

Cyanospiza. Similar in form to Guiraca, but culmen more curved, mandible more shallow, the angle and sinuations of the commissure less conspicuous. Color: ♂ more or less blue, without any bands on wing (except in C. amæna in which they are white); ♀ olive-brown. Nest in a bush; eggs plain bluish-white (except in C. ciris, in which they have reddish spots).

B. Wing and tail about equal. The smallest of American Conirostres. Nest in bushes. Eggs white, spotted.

Spermophila. Bill very short and broad, scarcely longer than high, not compressed; culmen greatly curved. Color: chiefly black and white, or brown and gray.

Phonipara. Bill more triangular, decidedly longer than deep, much compressed; culmen only slightly curved, or perfectly straight. Colors: dull olive-green and blackish, with or without yellow about the head.

C. Wing much shorter than the tail.

a. Head crested. Prevailing color red. Bill red or whitish.

Pyrrhuloxia. Bill pyrrhuline, very short, and with the culmen greatly convex; shorter than high. Hind claw less than its digit; not much larger than the middle anterior one. Tarsus equal to the middle toe. Nest in bush or low tree; eggs white, spotted with lilac and olive.

Cardinalis. Bill coccothraustine, very large; culmen very slightly convex. Wings more rounded. Feet as in the last, except that the tarsus is longer than the middle toe. Nest in bush or low tree; eggs white, spotted with lilac and olive.

b. Head not crested. Colors black, brown, or olive, without red. Bill dusky, or bluish.

Pipilo. Bill moderate; culmen and commissure curved. Hind claw very large and strong; longer than its digit. Tarsus less than the middle toe. Nest on ground or in low bush; eggs white sprinkled with red, or pale blue with black dots and lines round larger end.

Calamospiza bicolor.

This genus is well characterized by the large swollen bill, with its curved culmen; the large strong feet and claws; the long wings, a little longer than the tail, and with the tertials as long as the primaries; the first four quills about equal, and abruptly longest; the tail short and graduated.

The only group of North American Spizellinæ, with the tertials equal to the primaries in the closed wing, is Passerculus. This, however, has a differently formed bill, weaker feet, the inner primaries longer and more regularly graduated, the tail-feathers more acute and shorter, and the plumage streaked brownish and white instead of black.

A broad fulvous white band across the ends of the greater wing-coverts; edge of wing white. Tail-feathers with a white spot at the end of the inner web.

Young. Similar to the female; a faint buff tinge prevalent beneath, where the streaks are narrower; dark streaks above broader, the feathers bordered with buffy-white.

Hab. High Central Plains to the Rocky Mountains; southwesterly to Valley of Mimbres and Sonora; San Antonio, Texas, winter (Dresser, Ibis, 1865, 490). Fort Whipple, Arizona (Coues, P. A. N. S. 1866, 84). Parley’s Park, Utah (Ridgway).

Habits. This peculiar species, known by some writers as the Lark Bunting, and by others as the White-winged Blackbird, was first described by Townsend in 1837. He met with it when, in company with Mr. Nuttall, he made his western tour across the continent, on the 24th of May, soon after crossing the north branch of the Platte River. The latter writer regarded it as closely allied to the Bobolink, and described it as a Dolichonyx. He describes the birds as gregarious, consorting with the Cowbirds, and, at the time he met with them, uttering most delightful songs. Towards evening they sometimes saw these birds in all directions around them, on the hilly grounds, rising at intervals to some height, hovering and flapping their wings, and, at the same time, giving forth a song which Mr. Nuttall describes as being something like weet-weet-wt-wt-wt, notes that were between the hurried warble of the Bobolink and the melody of a Skylark. It is, he says, one of the sweetest songsters of the prairies, is tame and unsuspicious, and the whole employment of the little band seemed to be an ardent emulation of song.

It feeds on the ground, and, as stated by Mr. Townsend, may be seen in flocks of from sixty to a hundred together. It was, so far as their observations went, found inhabiting exclusively the wide grassy plains of the Platte. They did not see it to the west of the Black Hills, or the first range of the Rocky Mountains.

To Mr. Nuttall’s account Mr. Townsend adds that this bird is strictly gregarious, that it feeds on the ground, around which it runs in the manner of the Grass Finch, to which, in its habits, it seems to be somewhat allied. Mr. Townsend adds that, as their caravan moved along, large flocks of these birds, sometimes to the number of sixty or a hundred individuals, were started from the ground, and the piebald appearance of the males and females promiscuously intermingled presented a very striking and by no means unpleasing effect. While the flock was engaged in feeding, some of the males were observed to rise suddenly to considerable height in the air, and, poising themselves over their companions with their wings in constant and rapid motion, continued nearly stationary. In this situation they poured forth a number of very lively and sweetly modulated notes, and, at the expiration of about a minute, descended to the ground and moved about as before. Mr. Townsend also states that he met with none of these birds west of the Black Hills.

Mr. Ridgway also mentions that though he found these birds very abundant on the plains east of the Black Hills, he met with only a single specimen to the westward of that range. This was at Parley’s Park, among the Wahsatch Mountains.

Dr. Gambel, in his paper on the Birds of California, states that he met with small flocks of this handsome species in the bushy plains, and along the margins of streams, during the winter months. And Dr. Heermann states that he also found this species numerous in California, New Mexico, and Texas. Arriving in the last-named State in May, he found this species there already mated, and about to commence the duties of incubation.

Mr. Dresser found these birds common near San Antonio during the winter. In December he noticed several flocks near Eagle Pass. They frequented the roads, seeking the horse-dung. They were quite shy, and when disturbed the whole flock would go off together, uttering a low and melodious whistle. In May and June several were still about near Howard’s Rancho, and on his return from Houston, in June, he succeeded in shooting one in its full summer plumage, when its specific name is peculiarly appropriate. He does not, however, think that, as a general thing, any of them remain about San Antonio to breed.

They breed in great numbers on the plains of Wyoming Territory, and probably also in Colorado, Montana, and Dakota. The Smithsonian collection embraces specimens obtained in July from the Yellowstone, from Platte River, Pole Creek, the Black Hills, and Bridger’s Pass, indicating that they breed in these localities; also specimens from Texas, New Mexico, Sonora, and Espia, in Mexico, but none from California.

Dr. Kennerly, who met with these birds both in Sonora and at Espia, on the Mexican Boundary Survey, states that he observed them in the valley of the river early in the morning, in very large flocks. During the greater part of the day they feed on the hills among the bushes. When on the wing they keep very close together, so that a single discharge of shot would sometimes bring down twenty or thirty. Mr. J. H. Clark, on the same survey, also states that he sometimes found them occurring in flocks of hundreds. The greatest numbers were seen near Presidio del Norte. Great varieties of plumage were observed in the same flock. The food seemed to be seeds almost exclusively. They were very simultaneous in all their movements. Stragglers were never observed remaining behind after the flock had started. They are, he states, the most absolutely gregarious birds he has ever met with.

Dr. Coues, who regarded this bird as one highly characteristic of the prairie fauna, writes me that he met with it in great numbers in Kansas, soon after leaving Fort Riley, and saw it every day until he reached the Raton Mountains in New Mexico. “For two or three days, in fact, from Fort Larned to the mountains,” he writes, “I scarcely saw anything else. This was the first week in June, and most of the birds seemed to be paired and nesting, though occasionally a dozen or more were seen together, flocking like the Blackbirds that they strongly recall. They were in full song, and proved delightful vocalists. Sometimes they warble from some spray or low bush offering a stand a little above the level flower-beds of the prairie, but oftener they mount straight up, hovering high in the air on tremulous wings, pouring forth their melodious strains until, seemingly exhausted, they sink back to the ground. At such times it is interesting to watch two rival males, each straining every nerve to mount higher than the other, and sing more acceptably to its mate hidden in the verdure below. This habit of rising on the wing to sing, so famed in the case of the Skylark, seems not confined to particular species, but to be a forced practice of a number of different birds residing in open level regions, that do not afford the elevated perches usually chosen by woodland songsters for their performances. The ordinary flight of this species is altogether of a different character, being a low gliding motion, overtopping the weeds and bushes. That the birds were nesting at this time is rendered still more probable by the fact that the males noticed as we passed along were out of all proportion, in numbers, to the females seen. They were very heedless of approach, and any number could have been readily destroyed. I never saw any at Fort Whipple, or elsewhere in Arizona, though Dr. Heermann says that they are abundant in the southern portions of the Territory, and specimens are recorded from Lower California.”

Mr. Allen found the Lark Bunting one of the few birds that seemed strictly confined to the arid plains near Fort Hays, in Kansas. He met with it in great abundance, but only on the high ridges and dry plateaus, where they seemed to live in colonies. He describes them as very wary, and very tenacious of life, often flying long distances, even after having been mortally wounded. They seemed to delight to fly in strong winds, when most other birds kept in shelter. They sing while on the wing, hovering in the wind and shaking the tail and legs after the well-known manner of the Yellow-breasted Chat. Its song seemed to him to strongly resemble that of the Chat, with which, at such times, its whole demeanor strikingly accorded.

Dr. Heermann, in his Report on the birds collected in the survey on the 32d parallel, states that he first observed these birds on approaching the Pimos villages. They were associated with large flocks of Sparrows, gleaning grain and grass-seed upon the ground. When started up they flew but a short distance before they resumed their occupation. After crossing the San Pedro he again found them in large flocks. At Fort Fillmore, in Mesilla Valley, it was also quite common and associated with the Cowbird and Blackbird, searching for grain among the stable offals. He again met with them in Texas, in the month of April, most of them still retaining their winter coat. He describes the tremulous fluttering motion of the wings with which the male accompanies its song while on the wing as very much after the manner of the Bobolink, and he speaks of their song as a disconnected but not an unmusical chant. He found their nests on the ground, made of fine grasses, lined with hair, and in one instance he found the eggs spotted with faint red dashes.

At Gilmer, in Wyoming Territory, their nests were found by Mr. Durkee built on the ground, and composed of dry grasses very loosely arranged. The eggs, four or five in number, are of a uniform and beautiful light shade of blue, similar to those of the Euspiza americana. They measure .90 by .70 of an inch, are of a rounded-oval shape, and, so far as I have observed, are entirely unspotted, although eggs with a few reddish blotches are said to have been met with.
