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

A nest with eggs, procured at Fort Mohave by Dr. Cooper, is in the Smithsonian Collection (No. 7,276). The egg measures .93 by .70 of an inch, is obovate in shape, being much rounded at the smaller end. Its ground-color is a dull white, without any perceptible tinge of blue,—though possibly bluish when fresh,—with heavy dots and occasional delicate, hair-like, zigzag markings of black. These markings are wholly confined to the larger end. One of the eggs has these markings much finer, consisting of minute dots, more dense, and upon the apex of the larger end. The nest is loosely built and very bulky. Its external diameter is about six inches, and its depth three. The cavity is three inches wide and two deep. It is constructed almost entirely of strips of inner bark, the coarser, ribbon-like pieces being used on the outer portion, and the finer shreds composing the lining. Externally are also a few sticks about one quarter of an inch in diameter.

Sp. Char. Above dull grayish olive-green. Crown uniform chestnut. Forehead with superciliary stripe, and sides of the head and neck, the upper part of the breast and sides of the body, bluish-ash. Chin and upper part of throat abruptly defined white, the former margined by dusky, above which is a short white maxillary stripe. Under tail-coverts and sides of body behind brownish-yellow. Tail-feathers generally, and exterior of wings, bright olive-green, the edge and under surface of the wings bright greenish-yellow; edge of first primary white. First quill longer than eighth, fourth longest. Length, about 7 inches; wing, 3.20; tail, 3.65.

Hab. Whole of the Middle Province, including the Rocky Mountains and eastern slope of the Sierra Nevada; north to beyond the 40th parallel; south to Mexico.

In this species the wing is considerably rounded, the tertials considerably shorter than the primaries, and not exceeding the secondaries; the fourth quill longest, the first shorter than the sixth, the second and fifth quills considerably longer than the rest. The tail is long and considerably graduated, the outer feather half an inch shortest; the feathers broad and obtusely pointed, the corners rounded.

Pipilo chlorurus.

The extent of the chestnut of the crown varies somewhat; more extended probably in the males. The region on the side of the head, adjoining the nostrils, is whitish; the small feathers under the eye are spotted with the same. The posterior outline of the ash of the breast is much less sharply defined than the anterior.

Specimens vary in the brightness of the olive above, which is never as pure as that of the wings and tail. The olive of the tail, too, is darker than that of the wings.

Pipilo chlorurus.

A very young bird (1,896) has the whole under parts dull white, streaked and spotted on the sides of the throat and on the breast with dark brown. The crown and back are also thickly spotted. In 5,734 the ash of the breast has made its appearance; the middle of the belly is white, spotted; the chin white, encircled by spots. The spots above are restricted to near the head, and there is a small central patch of chestnut on the crown.

No. 1,896 is the original “Green-tailed Sparrow” killed July 12, 1834, by Townsend, and described in an extract of a letter to Mr. Audubon, published page 336 of Vol. V. of the Ornithological Biography.

Habits. Dr. Kennerly, who procured a specimen of this bird at San Elizario, Tex., December 16, states that it was obtained with some difficulty. For several successive days it was found in the same place, occupying a small clump of very thick weeds. When aroused, which was only accomplished with some effort, its flight was short, rapid, and decidedly irregular. Its motions on the ground were very awkward. This species was found by Mr. Ridgway very generally distributed throughout the fertile mountain portions of the interior. It was not seen by him in California, and was first met with in the ravines at the base of the eastern slope of the Sierra Nevada. On the high mountain-ranges it was a characteristic and the best-known singer, as well as one of the most abundant of the Fringillidæ, being found in all bushy places, from the bases to the summits of the mountains. It is exclusively a summer species, arriving at Carson City about the middle of April. He describes the usual note of this bird as very peculiar, and, as nearly as can be described, a sweet laughing utterance of the syllables keek-keek´, a little resembling the tweet of a Canary, but very musical. This curious note was generally uttered when anything unusual attracted its attention, such as the approach of an intruder. Then, with elevated tail and its very conspicuous red cap raised, it would hop familiarly and unsuspiciously about. He adds that it is a songster of high merit, in power and variety ranking very little below the song of the Chondestes grammaca. The song varies in the modulations greatly with the individual, but the same general style is preserved. At times it seemed to have a slight resemblance to the song of Bewick’s Wren, and at others to that of a Cyanospiza, and more rarely, to be the reproduction of a passage from the song of the Chondestes.

In the early part of July, near Austin, in the cañons of the mountains, he found these birds breeding in the greatest abundance, and later in the same month a few of its nests were found on the East Humboldt Mountains. All of its nests, with hardly an exception, were placed from eighteen inches to two feet above the ground, among the thick bushes of a species of Symphoricarpus, or “snow-berry,” which grows in great abundance upon the sides of the cañons of those mountains. The maximum number of eggs was four. It was also quite a common bird in the Wahsatch Mountains, though less abundant than the P. megalonyx.

Mr. Allen found this Finch quite numerous in Colorado Territory, and speaks of its song as very peculiar and very pleasing. It is said to resemble in no respect the eastern Towhee Finch, with which it is classed, but much more closely the group of Sparrows, so familiarly represented at the east by the White-throated, being like them in habits, song, and general aspect. It was more common among the foot-hills than on the plains. In Utah, according to Mr. Allen, this Finch begins to appear in numbers about September 20, from its breeding-haunts in the mountains.

Dr. Coues met with this species in Arizona, but only as a spring and autumn migrant. None remained there in summer to breed, and none were found there in the winter. In its migrations it passed rapidly by Fort Whipple, being found there only during the latter part of April and the beginning of May, and during the month of September. At those seasons it appeared to him the most silent and retiring of all the Pipilos. He found it very difficult to either observe its habits or to capture it. It winters sparingly at Fort Mohave.

Specimens of this bird were taken near Lookout Mountain by C. S. McCarthy, and at Gilmer, in Wyoming Territory, by Mr. Durkee.

Dr. Heermann, in his Report on the birds observed on the 32d. parallel, under Lieutenant Parke, mentions first meeting with this species near Tucson. They were frequenting, in numbers, the thick undergrowth, and were seeking seeds and insects on the ground. They seemed inclined to shun observation, and always kept in the most retired situations. They were sociable among themselves, going about singly or in pairs, associated with the Poospiza bilineata and two or three other kinds of Finch. When started they fly low, diving into the bushes, and soon disappear from sight. Occasionally, until reaching El Paso, Texas, birds of this species were met with, mingling with the flocks of migrating Fringillidæ. He there procured a pair apparently just entering upon incubation.

Instead of being suited by color, like most of the other Pipilos, to inhabit dark thickets and among dry leaves, this species is clad in a gayer livery, and seems well adapted for concealment in its summer resorts, and also among the growing vegetation of the lower country during the rainy season. Dr. Heermann found a few wintering in the Colorado Valley, and yet more at San Diego, but they left both places in March. He found them silent and shy, hiding very closely in the bushes, and feeding altogether on the ground. The only note he heard, resembled the crowing note of the California Quail.

Among the memoranda of Mr. Xantus, made near Fort Tejon, are the two following: “4,839, nest and two eggs (of Pipilo chlorurus) found in a dry hedge in Mr. Ritchie’s garden; 5,083, nest and eggs found in a dark garden-hedge.”

The eggs of the chlorurus are like those of no other Pipilo that I have met with. They are peculiar in shape, being nearly of an exact oval, neither end being apparently much more rounded than the other. Their ground-color is white with a bluish tint, over which is profusely diffused a cloud of fine dottings of a pinkish-drab. These markings are occasionally so fine and so thickly distributed as to give to the egg the appearance of a uniform color, or as an unspotted pinkish drab-colored egg. Occasionally the dots are deeper and larger, and more sparsely diffused.

In considering the eggs of the Pipilos in general we find certain variations which deserve more than a passing notice. Those of erythrophthalmus, oregonus, arcticus, and megalonyx are all fringilline in their characters, and have a marked affinity to eggs of Melospiza, Zonotrichia, and many other genera of this order. The eggs of aberti, fuscus, mesoleucus, and albigula are also all closely alike, and exhibit a very close resemblance to those of the Agelaii, and even of the Icteri, while the eggs of P. chlorurus, though of a fringilline character, are unlike either style.

Family ALAUDIDÆ.—The Larks

Char. First primary very short or wanting. Tarsi scutellate anteriorly and posteriorly, with the plates nearly of corresponding position and number. Hind claw very long and nearly straight. Bill short, conical, frontal feathers extending along side of the bill; the nostrils concealed by a tuft of bristly feathers directed forward. Tertials greatly elongate beyond the secondaries.

Subfamilies and Genera

Alaudinæ. Bill stout, short, and conical; nasal fossæ transverse and completely filled by the thick tuft of bristly feathers, and perforated anteriorly by a circular nasal opening. (Old and New World.)

Crown with a depressed soft crest of feathers, of normal structure; a spurious primary; tail deeply emarginate … Alauda.

Crown without a crest, but occiput with an erectile tuft of narrow elongated feathers on each side. No spurious primary; tail square, or slightly rounded … Eremophila.

Calandritinæ. Bill broader, more depressed, and straighter at the base; nasal fossæ longitudinal, large, elongated, the nasal opening rather linear. (Old World.)

Of the Alaudidæ only the two genera diagnosed above belong to the American continent; and one of them is properly only a wanderer from the Old World, while the other is cosmopolitan.

The most characteristic feature of the Larks among other oscine families is seen in the scutellation of the tarsus. The anterior half of this is covered by divided scales lapping round on the sides, but instead of the two plates which go one on each side of the posterior half and unite ultimately behind as an acute ridge, there is but one which laps round on the sides, and is divided into scales like the anterior ones, but alternating with them. The posterior edge of the tarsus is as obtuse as the anterior, instead of being very acute. There is a deep separating groove on the inner side of the tarsus; and there may be really but one plate divided transversely, the edges meeting at this place.

In the elongated hind claw and lengthened tertials, general style of coloration, mode of life, and manner of nesting, there is a decided approximation in the Alaudidæ to the Anthinæ, of the family Motacillidæ; but in these the posterior edge of the tarsus is sharp and undivided transversely, the toes more deeply cleft, the bill more slender, etc.,—their relations being rather nearer to the Sylvicolidæ than to the present family.

Genus ALAUDA, Linn

Alauda, Linn. S. N. 1735

Gen. Char. Bill very small, less than half the length of the head, conical; nostrils exposed; rictal bristles quite strong; commissure without notch; tarsus much longer than middle toe; lateral toes equal; posterior toe about as long as the middle, its claw longer than the digit, and nearly straight; claws of anterior toe very small. Wing long, pointed, the third and fourth (apparently second and third) quills longest, the second and fifth successively, a little shorter; the first so small as to be almost concealed; tertials much elongated, reaching about half-way from end of secondaries to tip of primaries; their ends emarginated; tail rather deeply emarginated, and a little more than half the length of the wing.

Habits. The famed Skylark of the Old World can rest a twofold claim to be included in a complete list of North American birds. One of these is their occasional occurrence in the Bermudas, and in Greenland. The other is their probably successful introduction near New York.

A few years since an attempt was made to introduce these birds, for which purpose several individuals were set at liberty on Long Island. For a short time they did well, and succeeded in raising one or more broods, but, owing probably to the constant persecution of all small birds by the foreign population of the neighborhood, the experiment nearly failed, and none were noticed in that vicinity. Within the last year or two, however, several pairs of these birds have been observed in Westchester County, and also on Long Island, by parties competent to recognize them, and hopes are now entertained that these desirable birds have obtained a foothold in this country.

According to Messrs. Dresser and Sharpe, the Skylark is found throughout the polar Arctic regions, from the British Islands eastward to Siberia and Northern China. A smaller subspecies is met with in Southeastern Europe, which does not present any character by which it can be separated from it. In Eastern Europe the Lark has been found as far north as the Faroe Islands, but has not been observed in Iceland. It reaches Christiania in March, and leaves in October. It has been found breeding in Lapland as far north as latitude 65°, and is a common summer visitant in Finland. Pallas found it abundant throughout Russia and Siberia, and Steller found it not only in Kamtschatka, but equally in the Kurile Islands and in those between Asia and America, so that its occurrence in our Alaskan territories may be regarded as a not improbable event.

The same writers also state that the Skylark has been twice recorded as occurring in Greenland and in America; and in another place they state that “the Skylark occasionally visits Greenland, and has been met with in the Bermudas.” In the latter place a storm-tried waif was taken by Mr. J. M. Jones after an easterly gale.

The Lark is a universal favorite in the Old World, and as a vocalist enjoys a reputation hardly second even to the far-famed Nightingale. It is an inhabitant of all the countries of Europe, and is said to be most abundant in the cultivated districts.

We only know of its song from caged specimens and from the testimony of European writers. Yarrell speaks of its notes as cheerful and exhilarating, fresh as the season of spring, and the admiration of all hearers. Its voice is described as powerful to an extraordinary degree, and its song wild and joyous. They sing while they fly, rising, with quivering wings almost perpendicularly, until they gain so great an elevation that they can no longer be distinguished; yet, while thus no longer visible, their wild music continues to be heard as that of some unseen spirits of the air. It is said that one familiar with their song can readily determine, by their notes, whether the singer is ascending, stationary, or descending. Occasionally, when at this great elevation, the Lark will close its wings and drop to the earth with the rapidity of a stone. At times it will sing while on the ground, but its most lively strains are poured forth during these flights. And though this bird will sing while in confinement, and is a favorite cage-bird, yet in singing they are said to flutter their wings, as if this motion were almost a necessary accompaniment to their song.

In regard to the song and its peculiarities writers are not quite in agreement. The general opinion seems to be that, while in the quality of its tone it is surpassed by the song of the Nightingale, the Bulfinch, and the Black-cap, it is unequalled in quantity, sprightliness, variety, and power. The Lark is in song eight months of the year, and during the summer months it sings from two in the morning, with very little intermission, until after sunset.

Mr. Macgillivray gives an excellent and graphic description of the habits of this bird, from which we extract a portion descriptive of its song. “It has been alleged,” he writes, “that the Lark ascends in a spiral manner, but my observation does not corroborate the statement. In rising it often passes directly upward, but with the body always horizontal, or nearly so, then moves in a curve, and continues thus alternately, but without a continued spiral motion. At first, the motion of the wings is uniformly fluttering; but afterwards it shoots them out two or three times successively at intervals, and when at its greatest height exhibits this action more remarkably. When it descends, the song is not intermitted, but is continued until it approaches the ground, when it usually darts down headlong, and alights abruptly. Frequently it resumes its song after alighting, and continues it for a short time, but more commonly it stops when it has reached the ground. Often a Lark may be seen hovering over a field, in full song, for a considerable time, at a small height. On the 4th of May, 1837, I observed a Lark perched on a half-burnt whin branch, where it remained singing a long time. I have often seen it perch on a wall, and several times on a hawthorn bush in a hedge; but it never, I believe, alights on tall trees.

“The song of the Lark is certainly not musical, for its notes are not finely modulated, nor its tones mellow; but it is cheerful and cheering in the highest degree, and protracted beyond all comparison. In a sunny day in April or May, when the grass-fields have begun to resume their verdure, it is pleasant to listen to the merry songster that makes the welkin ring with its sprightly notes; in the sultry month of July, still more pleasant is it to hear its matin hymn while the dew is yet on the corn; and in winter, should you chance to hear the well-known voice on high, it reminds you of the bright days that have gone, and fills you with anticipation of those that are to come. No doubt much of the pleasure derived from the Lark’s song depends upon association, but independently of circumstances and associations the song of the Lark imparts an elasticity to the mind, elevates the spirits, and suspends for a time the gnawing of corroding care. The carol of the Lark, like the lively fife, excites pure cheerfulness. In confinement this bird sings every whit as well as when at large, and when rapidly perambulating the square bit of faded turf in its cage, it enacts its part with apparently as much delight as when mounting toward heaven’s gate.”

This bird succeeds well in cages, and lives to a great age, Yarrell mentioning one that lived nearly twenty years in confinement. Its natural food is grain, the seeds of grasses, worms, and various kinds of insects. They begin to mate in April, and have two broods in a season. Their nest is always placed on the ground, often sheltered by a tuft of grass, or some other protection. The nests are woven of coarse grasses and stems of plants, and are lined with finer materials of the same. The eggs are five in number, have a grayish-white ground, occasionally a greenish-white, very generally sprinkled and blotched with markings of dark-gray and an ashy-brown, so profusely as to conceal the ground. They are oval in shape, slightly more pointed at one end, and measure .93 of an inch in length by .70 in breadth.

According to Selby, the young of the first brood are fully fledged by the end of June, and the second in August. The Lark evinces a very strong attachment to its young, and many interesting accounts are given by European writers of its intelligent endeavors to conceal and to protect its nest,—in one instance constructing an artificial dome of dry grass, where the natural protection had been cut away by mowers, and in another attempting to remove the young to a place of greater safety.

The Lark has, in several instances, been successfully induced to mate and rear her young in an aviary; and Mr. W. P. Foster, of Hackney, is quoted by Mr. Yarrell as authority for the statement, that, during the period of producing the eggs, the female has been heard to sing with a power and a variety of tone equal to the voice of her mate.

While his mate is sitting on her eggs, the male Lark, apparently timid at all other times, is remarkably bold, and drives away other birds that venture too near their nest. He not only watches over her and seeks to protect her, but assiduously supplies her with food.

Genus EREMOPHILA, Boie

Eremophila, Boie, Isis, 1828, 322. (Type, Alauda alpestris. Sufficiently distinct from Eremophilus, Humboldt, [Fishes,] 1805.)

Phileremos, Brehm, Deutschl. Vögel, 1831.

Otocoris, Bonaparte, 1839. (Type, Alauda alpestris, Gray.) (We are unable to find where the genus is named.)

Gen. Char. First primary wanting; bill scarcely higher than broad; nostrils circular, concealed by a dense tuft of feathers; the nasal fossæ oblique. A pectoral crescent and cheek-patches of black.

♂ Eremophila alpestris.

This genus differs from Melanocorypha in having no spurious first primary, although the other characters are somewhat similar. Calandritis of Cabanis, with the same lack of first primary, has a much stouter bill. The spurious primary, more depressed bill, and differently constituted nostrils and nasal fossæ of Alauda are readily distinctive.

Eremophila alpestris.

The type of this genus is the Alauda alpestris, Linn., a well-known cosmopolitan species, though the birds of the New World have been distinguished under distinctive names, as cornuta, chrysolæma, peregrina, etc. The examination and critical comparison of more than a hundred specimens from all parts of North America, however, has convinced us of the identity with alpestris of the several forms mentioned above, though it may be advisable to retain one or more of them as geographical races.

Species and Varieties

E. alpestris. Adult. Above pinkish-gray, varying to cinnamon, the pinkish deepest on nape and lesser wing-coverts; tail black (except two middle feathers), the outer feather edged with white.

THE SHORE LARK

Sp. Char. Adult male; spring. A frontal crescent, curving backward in a broad, sharply defined, superciliary stripe to the occiput; chin, throat and foreneck, and a crescent across middle of ear-coverts, whitish, either more or less tinged with yellow, or pure white. Lower parts, except laterally, white. A broad crescentic patch behind the frontal whitish crescent, running back on each side of the crown and terminating in an erectile tuft of narrow elongated feathers on each side of occiput, a patch covering the lores, nasal tufts, passing beneath the eye, and forming a broad “mustache” on the cheeks, with a convex outline behind and concave anteriorly, and a broad crescentic patch across the jugulum, deep black. A crescentic spot of grayish-drab across the ends of the auriculars. Posterior portion of the crown enclosed laterally between the “ear-tufts,” occiput, nape, lateral lower parts, lesser and middle wing-coverts, and upper tail-coverts, pinkish-brown; the sides and flanks with obsolete dusky streaks. Back, scapulars, rump, wings, and two middle tail-feathers, ashy-drab, the feathers darker centrally, forming rather conspicuous broad streaks on lower part of back; middle and secondary coverts, secondaries and primaries bordered terminally, quite conspicuously, with white. Tail (except the intermediæ) black; outer web of lateral feather almost entirely white, that of the next edged with the same.

Adult female; spring. Similar, but markings rather less sharply defined; a tendency to streaking of nape and crown; these streaks often displacing the continuous black of the anterior portion of crown. The “ear-tufts” less developed.

Winter adult. Similar to the spring dress, but the black areas obscured, more or less, by whitish borders to the feathers; the frontal whitish band less sharply defined. Breast with numerous more or less distinct deltoid specks of plumbeous, and the pinkish of the sides much tinged with the same. The dusky streaks above are broader and more conspicuous.

Young. First plumage, entirely different from the adult. Above dusky, variegated with whitish dots, sprinkled over the whole surface; these specks terminal on each feather, and of a deltoid form, becoming more transverse and crescentic on the scapulars and rump; each feather of the wings broadly bordered with pale brownish, approaching white on the coverts. The blackish areas are but faintly indicated by a dusky suffusion, generally very indistinct, across the breast, and over the cheeks; and variegated with badly defined, more dusky spots; lower parts, including post-ocular stripe, dull white; sides spotted with dusky.

The E. alpestris, as restricted, is represented in the collection by three perfect specimens, in the several stages of plumage described; while there is also a fine specimen from Astrachan, representing a white-throated race (“var. bei” on MS. label) of Central Asia. The series of American specimens is all that could possibly be desired, there being numerous examples from nearly the whole northern continent, from the Arctic regions to as far south as Bogota, and from coast to coast.
